Testing kxlibssl prng for tls module
by Daniel-Constantin Mierla 09 Oct '19

09 Oct '19

Hello Marco, I am writing to see if you can test the kxlibssl prng that I just added for tls module. I want to see if exposes the same issue you reported in: * https://github.com/kamailio/kamailio/issues/2077 If you can't test with master branch, you need to backport two commits: * https://github.com/kamailio/kamailio/commit/99eafac2d92533ba93cd8244173aef0… * https://github.com/kamailio/kamailio/commit/a52f05087a211bfecd36300907d0bff… Then set: modparam("tls", "rand_engine", "kxlibssl") The latest branch 5.2 has the code for setting custom prng backported. The idea behind kxlibssl prng is to reuse the function of the default libssl v1.1.x prng, but guarded by a kamailio specific mutex.

Error parsing parameter value
by Duarte Rocha 08 Oct '19

08 Oct '19

Greetings, I'm testing some parameters actions and i found a weird behaviour This is my code for the test : $var(Parameter_List) = "blue=twelve;green=twe\"lve\";yellow=\"twelve\""; xerr("Parameter List = $var(Parameter_List)"); xerr("Value of Parameter blue = $(var(Parameter_List){param.value,blue})"); xerr("Value of Parameter green = $(var(Parameter_List){param.value,green})"); xerr("Value of Parameter yellow = $(var(Parameter_List){param.value,yellow})"); The printed logs are the following : ERROR: <script>: Parameter List = blue=twelve;green=twe"lve";yellow="twelve" ERROR: <script>: Value of Parameter blue = twelve ERROR: <script>: Value of Parameter green = twe"lve" ERROR: <script>: Value of Parameter yellow = twelve I have also tried setting the string as : $var(Parameter_List) = 'blue=twelve;green=twe"lve";yellow="twelve"'; But the results were similar The "" are not recognized in some scenarios. Is this intended behaviour or should i submit it as a bug? Best Regards, Duarte Rocha

Bad BYE request
by Duarte Rocha 08 Oct '19

08 Oct '19

Greetings, This is a repeated problem, but i have more info now. Please help understand if there is a problem on my code or if there is any kind of Kamailio bug. On the first INVITE of every call i apply uac_replace_from() and uac_replace_to() in order to normalize numeration. I have the restore_mode set as "auto". The original numeration is : To : 351250000000 From : 351211455000 The INVITE is sent to the client with To and From like this and with the Record-Route headers (Kamailio has 2 Ips and inserts 2 Record-Routes) containing vsf and vst parameters to help the future restores : To: <sip:+351250000000@111.111.111.111> From: <sip:+351211455000@111.111.111.111 >;tag=BD583030373631320511EAE6 Record-Route: <sip:111.111.111.111;r2=on;lr;ftag=BD583030373631320511EAE6;tbk_i=2_2_Y;tbk_o=128_11_Y;vsf=AAAAABgGBAMDAAUBBQAJCnNyAwMcHwIdHQsWHwUMOA--;vst=AAAAABgGBAMHDQgJDQECA3RyAwMcHwIdGgQeHAIFOQ--;did=18e.5d62> Record-Route: <sip:111.111.111.111;r2=on;lr;ftag=BD583030373631320511EAE6;tbk_i=2_2_Y;tbk_o=128_11_Y;vsf=AAAAABgGBAMDAAUBBQAJCnNyAwMcHwIdHQsWHwUMOA--;vst=AAAAABgGBAMHDQgJDQECA3RyAwMcHwIdGgQeHAIFOQ--;did=18e.5d62> My client, upon receiving the INVITE, also does some changes in the numeration and sends a 183 reply with the following headers : Record-Route: <sip:111.111.111.111;r2=on;lr;ftag=BD583030373631320511EAE6;tbk_i=2_2_Y;tbk_o=128_11_Y;vsf=AAAAABgGBAMDAAUBBQAJCnNyAwMcHwIdHQsWHwUMOA--;vst=AAAAABgGBAMHDQgJDQECA3RyAwMcHwIdGgQeHAIFOQ--;did=18e.5d62> Record-Route: <sip:111.111.111.111;r2=on;lr;ftag=BD583030373631320511EAE6;tbk_i=2_2_Y;tbk_o=128_11_Y;vsf=AAAAABgGBAMDAAUBBQAJCnNyAwMcHwIdHQsWHwUMOA--;vst=AAAAABgGBAMHDQgJDQECA3RyAwMcHwIdGgQeHAIFOQ--;did=18e.5d62> From: "+351211455000" <sip:I2116446I_500@111.111.111.111 >;tag=BD583030373631320511EAE6 To: <sip:+351250000000@111.111.111.111>;tag=as3e46f684 After Kamailio processes the reply, To and >From are restored to it's original values and the reply is relayed : From: <sip:351211455000@111.111.111.111 >;tag=BD583030373631320511EAE6 To: <sip:351250000000@111.111.111.111>;tag=as3e46f684 Here, the restore works perfectly. By the end of the call the client sends me a BYE request with Route, From and To like this : Route: <sip:111.111.111.111;r2=on;lr;ftag=BD583030373631320511EAE6;tbk_i=2_2_Y;tbk_o=128_11_Y;vsf=AAAAABgGBAMDAAUBBQAJCnNyAwMcHwIdHQsWHwUMOA--;vst=AAAAABgGBAMHDQgJDQECA3RyAwMcHwIdGgQeHAIFOQ--;did=18e.5d62>,<sip:212.13.40.205;r2=on;lr;ftag=BD583030373631320511EAE6;tbk_i=2_2_Y;tbk_o=128_11_Y;vsf=AAAAABgGBAMDAAUBBQAJCnNyAwMcHwIdHQsWHwUMOA--;vst=AAAAABgGBAMHDQgJDQECA3RyAwMcHwIdGgQeHAIFOQ--;did=18e.5d62> From: <sip:+351250000000@111.111.111.111 >;tag=as3e46f684 To: "+351211455000" <sip:I2116446I_500@111.111.111.111 >;tag=BD583030373631320511EAE6 Here, the difference between 183 and BYE seems to be only in the Route\Record-Route are built (2 Headers or one header with 2 uri). Now, there are a couple of problems relaying the BYE that seem to me to be related to auto replace. This BYE message isn't logged on the onsend-route and it logs a couple of errors : ERROR: <core> [core/parser/msg_parser.c:164]: get_hdr_field(): bad to header ERROR: <core> [core/parser/msg_parser.c:337]: parse_headers(): bad header field [To: "+351211455000" <sip:Q4525417L_<:C212.13.38.148>;tag=3DC130303736313205201F18#015#012Call-ID: 020FAAC7] ERROR: dialog [dlg_handlers.c:666]: pre_match_parse(): bad request or missing CALLID/TO hdr :-/ ERROR: <core> [core/parser/parse_addr_spec.c:719]: parse_addr_spec(): unexpected char [<] in status 6: ["+351211455000" <sip:Q4525417L_] . Despite not being logged on onsend_route and creating some errors, the BYE is still relayed like this : From: < sip:351250000000@111.111.111.111>;tag=as3e46f684 To: "+351211455000" <sip:Q4525417L_<:C111.111.111.111>;tag=BD583030373631320511EAE6 This, naturally, generates a "400 Bad Request" reply from the next equipment. I've also logged the $tU values along the code for BYE requests and it always logs the "I2116446I_500", so i don't know if my code can be the cause of this. A couple of questions and comments - What can i do to better debug this issue? I want to be sure if the problem comes from my code of if it is a Kamailio issue. Right now i'm not sure where to look. - Can a request be sent without passing on onsend_route ? I have used this code to "catch" the BYE, which works for other BYEs - if( $rm == "BYE") {xerr("On send : To User = $tU");}

SIP-links adjacency
by Oleg Belousov 07 Oct '19

07 Oct '19

Hello. In our setup kamailio perfoms some logic depending on call direction, inbound or outbound. Call direction is identified by 2 SBC IP (IP_inbound/IP_outbound), we currently use for that 2 dispatcher groups and that is working fine. Now number of peer nodes increased from one SBC till few tens, but we still need to keep SIP-links adjacency, meaning that call which arrived from SBC_N IP_inbound need to be submitted via same SBC_N IP_outbound and vice versa. There could be few approaches to implement that requirement, I'm wondering if can use existing dispatcher function/select destination logic to support SIP-links adjacency. -- obelousov.tel

q_malloc crash on Kamailio 5.2.3 with http_async_query function
by Michal Škuta 07 Oct '19

07 Oct '19

Hello everyone, I am adding some new features to our Kamailio server, one of them is sending HTTP POST request after calls end. We created simple route like this and we are calling it from event_route[dialog_end]: route[HTTP_TEST_CALL_END] { t_newtran(); $http_req(body) = "TEST"; http_async_query("http://192.168.6.23:2080/cdr_http", "HTTP_TEST_REPLY"); } Problem is that Kamailio is crashing on line *http_async_query*, the log from crash: Oct 3 16:13:37 sip_server /opt/ipgate/kamailio/sbin/kamailio[5331]: CRITICAL: <core> [core/mem/q_malloc.c:149]: qm_debug_check_frag(): BUG: qm: prev. fragm. tail overwritten(c0003032, abcdefed)[0x97a7ff3c:0x97a7ff58]! Memory allocator was called from http_async_client: hm_hash.c:82. Fragment marked by http_async_client: hm_hash.c:71. Exec from core/mem/q_malloc.c:384. In older Kamailio 4.4 I am using http_async_query with no problems. I opened issue on GitHub: https://github.com/kamailio/kamailio/issues/2091 I hope that is ok, more logs and core dump is in the issue. Any help or suggestion is welcomed. Sincerely Michal

using http_async_query
by David Villasmil 05 Oct '19

05 Oct '19

Hello guys, So, i'm using http_async_query to send out requests. It may happen that the request times out, in this case, i would like to try a new destination, i.e. with ds_select (NOT ds_delect_dest or ds_next, because i don't want the $du to be set, since in my case i don't actually have a SIP packet). Is is possible to get the original http request url in the http_async_query timeout route? Thanks! Regards, David Villasmil email: david.villasmil.work(a)gmail.com phone: +34669448337

storing vars in htable
by David Villasmil 05 Oct '19

05 Oct '19

Hello guys, I'm storing some data in an htable, like so: $var(http_query) = "/default/en_US/send.html?u=user&p=pass&l=$var(next_channel)&n=$var(to)&m=$var(message)"; then i need to store it: $sht(http_requests=>$http_req_id) = $var(http_query); But what's stored is the actual vars, not the the values, it's stored like: sh store: /default/en_US/send.html?u=user&p=pass&l=$var(next_channel)&n=$var(to)&m=$var(message) Why is that? shouldn't the vars be parsed?

Re: [SR-Users] Call limit through shared database
by Olli Attila 04 Oct '19

04 Oct '19

Hello Henning, I tried the dialog profile sharing with dmq&dialog modules and now the syncing works between the two kam nodes. Thank you! Is there a way to keep the dialog profiles persistent (load from db if kam restarts)? I was thinking a scenario where kam1 has already the call limit maxed out and kam2 suddenly reboots and after reboot, kam2 should be aware of dialogs on kam1 to be able to limit calls again correctly. Cheers, Olli

Re: [SR-Users] Call limit through shared database
by Olli Attila 04 Oct '19

04 Oct '19

Hello, I had the following enabled in db_mode param and now it is actually working: *1 - REALTIME* - any dialog information changes will be reflected into the database immediately. Restarting either of the kam1 or kam2 proxies "on the fly" will result in retrieving dialog profiles correctly from database. Cheers, Olli

Record-Route management
by Duarte Rocha 03 Oct '19

03 Oct '19

Greetings, I have multiple IPs in my Kamailio. In some scenarios, the caller and the called connect to different IPs and in others, they use the same IP. Currently i'm running with the RR's module "enable_double_rr" parameter set so i can have one Record-Route for each IP used on the call. However, in the scenario that both caller and called have the same IP, i would like to only have on Record-Route in order to save on the pactet's size. Is this possible to have those two scenarios on the same Kamailio ? Best Regards

Development is open for future release of v5.4.x series
by Daniel-Constantin Mierla 03 Oct '19

03 Oct '19

Hello, the branch 5.3 was created late last evening, therefore the master branch is open for adding new features, to be part of future release series v5.4.x. Any bug fix committed to master that applies to 5.3.x or older stable branches should be backported as usual with "git cherry-pick -x ..." to appropriate branches like 5.3 or 5.2. Expect that v5.3.0 will be released in a few weeks from now. Based on the workflow used during the past years, the next future release v5.4.0 should be out after another 8-10 months of development, plus 1-2 months of testing, so sometime in close to the end of spring 2020 or afterwards.

Branch 5.3 has been created
by Daniel-Constantin Mierla 03 Oct '19

03 Oct '19

Hello, the branch 5.3 has been created, to be used for releasing v5.3.x series. To check out this branch, the following commands can be used: git clone https://github.com/kamailio/kamailio kamailio-5.3 cd kamailio-5.3 git checkout -b 5.3 origin/5.3 Pushing commits in this branch: git push origin 5.3:5.3 Note that 5.3 is an official stable branch, so only bug fixes, missing kemi exports (discuss on sr-dev if not sure) or improvements to documentation or helper tools can be pushed to this branch. You may notice a bit of more activity on tls (some issue is under work) and siptrace (a bit of cleanup for coherence might be done) modules, but over all no new features will be pushed there. As usual, if there is a bug fixed, commit and push first to master branch and then cherry pick to 5.2 branch: git cherry-pick -x COMMITID In few weeks, the first release from branch 5.3 will be out, respectively Kamailio v5.3.0.

Call limit through shared database
by Olli Attila 01 Oct '19

01 Oct '19

Hello, I have 2 kam instances using one shared database and both kam servers running the same routing logic code. Kamailio servers are configured to use the same database as dialog backend. I am limiting the concurrent dialogs in the following way but it seems that kamailio is using its own memory to read profile size rather than the db. Second kam is not aware of the dialog profiles that the first kam wrote to the shared db. Is there a way to get multiple kam instances to read profile size from the same database when calling the get_profile_size function? modparam("dialog", "profiles_with_value", "concurrent_calls") modparam("dialog", "dlg_flag", 4) modparam("dialog", "db_url", DBURL) modparam("dialog", "db_mode", 1) route[LIMIT_CALLS] { if (!dlg_isflagset("1")) { # $td – gateways, $fu - user if (get_profile_size("concurrent_calls", "$fu", "$avp(calls)")) { if ($avp(calls) >= 3) { xlog("L_INFO", "Concurrent calls $fu at limit"); send_reply("503", "Calls limit reached"); exit; } else { dlg_manage(); dlg_setflag("1"); set_dlg_profile("concurrent_calls", "$fu"); } } } } Cheers, Olli

Kamailio Charging
by Jack R 01 Oct '19

01 Oct '19

Hi, Does Kamailio provide some charging functionality? If yes, then how do we go about setting it up? like what module/configuration? and Database tables to see/touch? I see these links: https://www.kamailio.org/docs/modules/4.2.x/modules/ims_charging.html https://www.kamailio.org/w/2013/07/documentation-on-charging-in-ims/ Or Do we need separate software like example cgrates for charging? (also a side question do we have any other open-source like cgrates) Any information would be helpful. Thanks and Regards, Jack.

Would you please keep "Users Mailing List" <sr-users(a)lists.kamailio.org> in tracking. :) That is straight froward. There is no change in sending the request from Kamailio to Asterisk.

tcp_accept_haproxy questions
by Grant Bagdasarian 27 Sep '19

27 Sep '19

Hello, The docs mention regular TCP connections not being accepted anymore once this is enabled. I assume UDP is unaffected and both proxyprotocol and udp may live side by side? Also, does this play nicely with WebSockets? Taking into account the Websocket connection being setup through a proxy protocol supporting proxy. Regards, Grant

ims_ipsec_pcscf: maybe core dump due to maximum count of connections
by Valentin Christoph 26 Sep '19

26 Sep '19

Hi, Doing some tests with the module ims_ipsec_pcscf, we encountered a core dump during startup of Kamailio and would like to understand the correct behavior. We assume the ipsec_max_connections parameter was the root cause --> how many max connections have been actually tested? Can it be that ipsec_client-port and ipsec_server_port were too close together (some overlapping)? Thx Christoph

Kamailio ARM support improved, tests
by Henning Westerholt 25 Sep '19

25 Sep '19

Hello, as part of the testing for 5.3.0 I looked into the ARM support in Kamailio. Previously the core used some deprecated assembler functions for atomic operations (locking etc..). There was also no native support for the ARM v7 architecture available. After several fixes and extensions both topics should be now much improved. I did today a lot of tests on Rasberry Pi and also some benchmarking (will send another e-mail when the report is ready). If you use Kamailio on another embedded ARM (>= v6) system it would be great if you also give it a try. Use git master revision ccc0eb6d12a1d (or newer) for your tests. Please report eventual issues to the sr-dev list.

Development for v5.3.x is frozen
by Daniel-Constantin Mierla 25 Sep '19

25 Sep '19

Hello, the formal notification that the development for the next major version 5.3.0 is now frozen. The focus has to be on testing the master branch. Also, the master branch should not get commits with new features till the branch 5.3 is created, expected to happen in 2-4 weeks, a matter of how testing goes on. Meanwhile, the commits with new features in the C code can be pushed to personal branches, pull requests can still be done, but they will be merged after branching 5.3. Can still be done commits with documentation improvements, enhancements to related tool (e.g., kamctl, kamcmd) and exporting missing KEMI functions to the modules already exporting most of the other functions (done for previous releases, because likely that was a fail to notice, all functions should be exported for a module at the same time). Once the branch 5.3 is created, new features can be pushed again to master branch as usual. From that moment, the v5.3.0 should be out very soon, time used for further testing but also preparing the release of packages. If someone is not sure if a commit brings a new feature, just make a pull request and it can be discussed there on github portal or via sr-dev mailing list. A summary of what is new in upcoming 5.3 is collected at: * https://www.kamailio.org/wiki/features/new-in-5.3.x Upgrade guidelines will be collected at: * https://www.kamailio.org/wiki/install/upgrade/5.1.x-to-5.3.0 Everyone is more than welcome to contribute to the above wiki pages, especially to the upgrade guidelines, to help everyone else during the migration process from v5.2.x to 5.3.x.

Extract user from AOR
by Grant Bagdasarian 25 Sep '19

25 Sep '19

Hello, I've been trying to extract the user part from an AoR using transformations in Python (KEMI), but without success. The reg_fetch_contacts function has been called successfully before trying to access the AoR. None of the below statements work for me. They all return None. user = _.pv.get("$(ulc(profile=>aor){uri.user})") user = _.pv.get("$(ulc(profile=>aor){tobody.user})") or _.pv.sets("$var(aor)", _.pv.get("$(ulc(profile=>aor))")) user = _.pv.get("$(var(aor){tobody.user})") user = _.pv.get("$(var(aor){uri.user})") I'm not sure what's causing the None result. Could it be the curly braces being used for string interpolation in Python? Or are these transformations not able to extract the value since the AoR has the following format: user@domain? If the same can be accomplished in another way, please let me know. Regards, Grant

Problem restoring To and From (uac_replace)
by Duarte Rocha 24 Sep '19

24 Sep '19

Greetings, I'm getting some errors with the auto restore of From and To from UAC Module. After the restore, the URI has lots garbage and it's not like the original. I think the problem lies on the way the client sends the Route Header to me, but i'm not sure. When Kamailio sends the INVITE Record-Route are like this : Record-Route: <sip:xxx.xxx.xxx.xxx;................> Record-Route: <sip:aaa.bbb.aaa.bbb;................> However, when my client sends a BYE to finish the call, the Route are on this mode : Route: <sip:aaa.bbb.aaa.bbb;................>,<sip:xxx.xxx.xxx.xxx;................> The module's documentation says this : "One uses the rr module and appends to the Record-Route header a parameter containing some strings from which the original and new URI can be computed. The problem with this mode is that it relies on the fact the parties will send the Route exactly as it was received. In case there is a change, the resulting URIs will not be correct." Can this change by the client be the cause of this issue? Is there anything i can do to avoid this? Best Regards, Duarte Rocha

qm_find_free() Free fragment not found, called from xcap_server, no more pkg
by Cody Herzog 23 Sep '19

23 Sep '19

Hello. Recently, for the first time, we experienced an apparent memory issue in our production environment. Here's an example of the relevant log messages: Sep 13 18:55:22 SIPCOMM /usr/local/sbin/kamailio[2302]: ERROR: <core> [core/mem/q_malloc.c:286]: qm_find_free(): qm_find_free(0x7fd8bbcfc010, 134648); Free fragment not found! Sep 13 18:55:22 SIPCOMM /usr/local/sbin/kamailio[2302]: ERROR: <core> [core/mem/q_malloc.c:419]: qm_malloc(): qm_malloc(0x7fd8bbcfc010, 134648) called from xcap_server: xcap_server.c: ki_xcaps_put(549), module: xcap_server; Free fragment not found! Sep 13 18:55:22 SIPCOMM /usr/local/sbin/kamailio[2302]: ERROR: xcap_server [xcap_server.c:552]: ki_xcaps_put(): no more pkg Sep 13 18:55:22 SIPCOMM /usr/local/sbin/kamailio[2252]: ERROR: app_perl [kamailioxs.xs:487]: XS_Kamailio_log(): 500 Server error The failed operation was the XCAP server module trying to generate a very large RLS contact list for a user. The issue only impacted users with very large lists, as though a large contiguous block of memory could not be found, whereas other smaller allocations continued to work fine. We believe the requested allocation was around 112 KB in size. The server had been up for 14 days. We were able to work around the issue temporarily by just restarting the Kamailio service. It's unusual, because our production server is often up for months, and we've never seen this issue before. The load on production is increasing slowly due to an increased concurrent user count, so that might be related. Before restarting the service on production, we captured the output of the following commands: kamctl stats shmem kamcmd mod.stats all shm kamcmd pkg.stats kamcmd mod.stats all pkg Here's the shared mem output: { "jsonrpc": "2.0", "result": [ "shmem:fragments = 27240", "shmem:free_size = 447203296", "shmem:max_used_size = 116175576", "shmem:real_used_size = 89667616", "shmem:total_size = 536870912", "shmem:used_size = 68824240" ], "id": 6934 } Here's the pkg output for the particular PID which was throwing the errors: { entry: 34 pid: 2302 rank: 14 used: 2415864 free: 4949688 real_used: 3438920 total_size: 8388608 total_frags: 1951 } We didn't see anything obvious in the stats output which explains the issue. We've been trying to reproduce the issue in a dev environment using simulated higher than production load running for many days, but so far we've had no luck. We've been monitoring memory stats over time, but we don't see any obvious leaks or issues. We've searched various past threads, but didn't find any obvious answers.

Using static entries with usrloc
by George Diamantopoulos 23 Sep '19

23 Sep '19

Hello, Normally I wouldn't be asking this but I was surprised to find no reference to anyone doing this online. I need to have a few AoRs with static entries in kami's location table, which will always be reachable at their contacts without ever having to register with Kamailio. Am I right in thinking that merely INSERTing respective rows in kamailio's location DB backend will do the trick? Is there anything I need to worry about, like contacts being periodically purged? If yes, how do I prevent that from happening? And will kamailio always query the DB when performing location lookup or do I need to restart upon inserting new records (to purge caches, for example)? Lastly, I'm not sure how to treat some fields present in usrloc tables like ruid, expires (can I set this to NULL?), callid and cseq (which is irrelevant since there's no REGISTER), flags, cflags and methods. Thanks, George

In preparation for the 5.3 release, I've been testing the following configuration change for TCP/TLS connections: https://github.com/kamailio/kamailio/commit/ 8bba208fe6ae7ccb4c92362b8c33f1530b9f56da route[REQINIT] { # no connect for sending replies set_reply_no_connect(); if(has_totag()) { # no connect for requests within dialog set_forward_no_connect(); } This change creates issues when a UAC TLS INVITE routes to an upstream gateway using TLS to port 5061 (via the LCR module). Kamailio sends the initial outbound TLS connection from a local ephemeral port. The TCPOPS tcp_keepalive_enable function issues keepalives from the local ephemeral port to the gateway port 5061: https://kamailio.org/docs/modules/stable/modules/ tcpops#tcpops.f.tcp_keepalive_enable Even so, the TLS connection eventually times out, after which in-dialog requests from the UAC are no longer able to reach the upstream gateway. ERROR: tm [../../core/forward.h:293]: msg_send_buffer(): tcp_send failed WARNING: tm [t_fwd.c:1570]: t_send_branch(): sending request on branch 0 failed ERROR: sl [sl_funcs.c:372]: sl_reply_error(): stateless error reply used: Unfortunately error on sending to next hop occurred (477/SL) I figure I must be doing something wrong with my TCPOPS here. Is a TLS connection to an upstream gateway supposed to be maintained throughout the duration of a call? -- Anthony - https://messinet.com F9B6 560E 68EA 037D 8C3D D1C9 FF31 3BDB D9D8 99B6

Info: initialization of libssl 1.1.+ with PTHREAD_PROCESS_SHARED attribute for pthread mutex and rwlock
by Daniel-Constantin Mierla 21 Sep '19

21 Sep '19

Hello, after couple of months waiting for feedback about the workaround with the preloaded shared library to set the PTHREAD_PROCESS_SHARED attribute for pthread mutex/rwlock in order to avoid deadlocks and as it seems to be the solution, I just pushed a few commits to move that code in the core of kamailio. It this way the initialization with the PTHREAD_PROCESS_SHARED attribute is done by default when libssl v1.1 is detected at compile time, without the need of using the approach with a preloaded library. The shared library is still kept in the tls module: * https://github.com/kamailio/kamailio/tree/master/src/modules/tls/utils/open… Probably is going to be removed in the near future. I am asking the community members that use Kamailio on systems with libssl v1.1+ to test the master branch and give feedback. The master branch is anyhow in testing phase for preparing the next major release v5.3.0, so it will help for that as well. If no issue is going to be reported soon, the commits will be backported to stable branches, to re-enable smooth use of Kamailio with libssl v1.1+. When libssl v1.1+ is detected, the core links with pthread, but that was already present in the Makefiles.defs for different compile options. The pthread more or less a default library on linuxes/unixes, so this should not introduce any major dependency to the Kamailio core.

Possible locking issue in usrloc module in file udomain.c
by Rupesh Kumar 18 Sep '19

18 Sep '19

Hi , Currently I am running kamailio 4.2 and now upgrading to kamailio 5.2 and was just going thru the changes. In the file modules/usrloc/udomain.c inside the function free_udomain( ) , it appears that we are not protecting via lock_ulslot and unlock_ulslot doing free. Could it cause some race condition ? May be its intentional but going thru the github history its there since day 1. I checked all branches in kamailio 4.x and we have the protection. In 4.x void free_udomain(udomain_t* _d) { int i; if (_d->table) { for(i = 0; i < _d->size; i++) { lock_ulslot(_d, i); deinit_slot(_d->table + i); unlock_ulslot(_d, i); } shm_free(_d->table); } shm_free(_d); } In 5.x void free_udomain(udomain_t* _d) { int i; if (_d->table) { for(i = 0; i < _d->size; i++) { deinit_slot(_d->table + i); } shm_free(_d->table); } shm_free(_d); }

NAT problem
by Arnout Van Den Kieboom 18 Sep '19

18 Sep '19

Hi, First of all, I'm really new to Kamailio. So sorry if I ask a stupid question, or perhaps a really weird one. I started using kamailio in a test environment about a week ago. for setup i have the situation for inbound calls: Carrier --> FW (NAT) --> Kamailio for outbound to an asterisk box i have: Kamailio --> FW (NAT) --> Asterisk for outbound to users i have: Kamailio --> FW (NAT) --> sip-phone (yealink) or grandstream During that time i was able to : Set up calls to users, Use the dispatcher module use the avpops module to do data lookups. Get calls from asterisk to kamailio user to work. Also calls between users (even though behind nat) are having good audio. I have installed rtpproxy and it works nicely. There is just one situation where it fails: Carrier --> FW (NAT) Kamailio --> asterisk There is only one way audio (from asterisk to carrier) but not from carrier to asterisk. I believe I need to do something with the rtp proxy module ... and tried different things (forcing the r flag, forcing the w flag) Any idea where I might need to start looking? It's been driving me crazy... Thanks Pemp

app_lua: invalid Lua environment attributes or parameters
by Yuriy Gorlichenko 18 Sep '19

18 Sep '19

Hi! Im using kamailio 5.1.8 with app_lua and getting this message during startup of kamailio. Looks like I forgot to add something at the module setup, but cant figure out what is wrong. My setup of app_lua is: modparam("app_lua", "load", "/etc/kamailio/extended/main.lua") modparam("app_lua","reload",1) modparam("app_lua","register","textops") app_lua [app_lua_sr.c:1599]: sr_kemi_lua_exec_func_ex(): invalid Lua environment attributes or parameters starting kamailio service with kamailio -f /etc/kamailio/extended/main.lua Also here is little bit confusing me that in case of use "KSR" everywhere I'm getting message about "sr"... Thx in advice

dedicated bearer - Kamailio settings
by Jack R 18 Sep '19

18 Sep '19

Hi, We have installed Kamailio as IMS setup pcscf icscf scscf - 3 instances running on Ubuntu. I have done the attached (image) settings to create dedicated bearer in nextepc as advised by this link: https://github.com/open5gs/nextepc/issues/180 Do I need to do some setting in Kamailio server side (maybe in pcscf cfg files etc.to take some information from PCRF) to make dedicated bearer work end to end or that is all (just configure the new apn in the phone) rest will be taken care itself? Thanks and Regards, Jack.

Once we truncated it, kamailio started working again. Is there a limit to how many records msilo can handle?

Kamailio+B2BUA on IPv4-only and NAT64 Apple app store tests
by Anthony Alba 17 Sep '19

17 Sep '19

Hi folks, I'm wondering what you do to pass Apple app store tests (IPv6-only NAT64/DNS64 scenario) with the iOS app likely to put IPv6 addresses in the SDP, when Kamailio and your B2BUA(Asterisk, FreeSWITCH,...) are IPv4-only endpoints. By "pass" I mean media flowing + SIP working - not sure the app store gatekeepers would actually test media, but it would be nice to have a robust solution. Strictly speaking, this is not a Kamailio's problem but a media SDP/<your-rtp-proxy-of-choice> problem. But since everything is so closely intertwined I'm wondering where you choose to the location the "solution". I have noticed that if Kamailio is IPv4-only and it "sees" IPv6-addresses(Contact, Via headers??) it will try to resolve the IPv6-address as a DNS name! The Wikipedia article on NAT64 mentions 464XLAT(RFC 6877) and Port Control Protocol (RFC 7225), but those seem to be deep rabbit-holes... Cheers Anthony Alba

Hi, After a month of fight with SIP signalling I made it but now I have problem with incoming audio from Asterisk. Kamailio and Asterisk are their own public IPs I dont use rtpproxy. When Asterisk sends rtp I'm able to see RTP on my router but it not going to my computer. Maybe somebody have idea why ?

Using $shv within current call only
by Zhan Bazarov 13 Sep '19

13 Sep '19

Hello, we ran into a trouble with sharing variable into reply route... We are going to match asterisk's uniqueid with rtpengine records like this: route[from_asterisk]{ $var(UniqueId)=$hdr(X-UniqueId); $var(rtp_flags) = $var(rtp_flags) + " label={uid:$var(UniqueId),stream:outgoing} record-call=on"; rtpengine_manage($var(rtp_flags)); } it nicely work for outgoing request, but doesn't for reply.... reply_route[from_pstn]{ rtpengine_manage("replace-origin replace-session-connection ICE=remove RTP/AVP rtcp-mux-demux label={uid:$var(UniqueId),stream:outgoing"); } and it doesn't work... The one possible way what we found its using $shv instead of $var/$avp... But its unsecure way, cuz it may confus our bussines logic... Do you have any idea how to implement this, how we can assign $shv within current call only? Many thanks!

Issue with <null> and 0 when comparing vars
by Joel Serrano 13 Sep '19

13 Sep '19

Hello, I'm running into what I believe a weird situation when comparing <null> to 0. I have the following lines: xlog("L_NOTICE", "DEBUG: sel(contact.expires)=$sel(contact.expires) - hdr(Expires)=$hdr(Expires)\n"); if ($hdr(Expires)==0 || $sel(contact.expires)==0) { xlog("L_NOTICE", "[end] removed user location\n"); } else { xlog("L_NOTICE", "[end] saved user location\n"); } I registered with 3 devices, one sends expires as header, another as contact param, and the last uses both header AND contact param. My surprise was this: 1- Both header and contact param: Sep 12 19:37:48 csbc01 csbc[8036]: NOTICE: {1 4 REGISTER 02c3ea6ee623916d37532188031017c9@0:0:0:0:0:0:0:0} <script>: DEBUG: sel(contact.expires)=600 - hdr(Expires)=600 Sep 12 19:37:48 csbc01 csbc[8036]: NOTICE: {1 4 REGISTER 02c3ea6ee623916d37532188031017c9@0:0:0:0:0:0:0:0} <script>: [end] saved user location 2- Only contact param: Sep 12 19:36:15 csbc01 csbc[8035]: NOTICE: {1 40629 REGISTER f2cbaa53-eabfd633(a)84.121.150.224} <script>: DEBUG: sel(contact.expires)=600 - hdr(Expires)=<null> Sep 12 19:36:15 csbc01 csbc[8035]: NOTICE: {1 40629 REGISTER f2cbaa53-eabfd633(a)84.121.150.224} <script>: [end] removed user location 2- Only header: Sep 12 19:29:33 csbc01 csbc[8033]: NOTICE: {1 402 REGISTER 2_1804628355(a)192.168.30.31} <script>: DEBUG: sel(contact.expires)=<null> - hdr(Expires)=3600 Sep 12 19:29:33 csbc01 csbc[8033]: NOTICE: {1 402 REGISTER 2_1804628355(a)192.168.30.31} <script>: [end] removed user location I can workaround the header by using is_present_hf() before comparing, I can also probably parse the $ct to see if it has some Expires in it, but I really want to know if my understanding is incorrect and I'm doing something wrong or if this is a bug? Thanks! Joel.

Testing server up with SIP OPTIONS/netcat
by Andrew White 13 Sep '19

13 Sep '19

Hi all, As part of a custom monitoring solution, I’m writing a simple script that sends an OPTIONS via netcat to a Kamailio server. However the server doesn’t appear to like it. Here’s the text - options.sip: OPTIONS sip:10.0.0.10 SIP/2.0 Via: SIP/2.0/UDP 10.0.0.20:5060 From: <sip:monitoring@10.0.0.20> To: sip:monitoring@10.0.0.10 Call-ID: monitoring(a)10.0.0.20 CSeq: 1 OPTIONS I’m running the following command from the 10.0.0.20 machine: nc -u 10.0.0.10 5060 < options.sip And I get the following error in the Kamailio logs: ERROR: <core> [core/parser/parse_cseq.c:56]: parse_cseq(): method terminated unexpectedly ERROR: <core> [core/parser/parse_cseq.c:92]: parse_cseq(): bad cseq ERROR: <core> [core/parser/msg_parser.c:144]: get_hdr_field(): bad cseq ERROR: <core> [core/parser/msg_parser.c:337]: parse_headers(): bad header field [CSeq: 1 OPTIONS] ERROR: <core> [core/parser/parse_cseq.c:56]: parse_cseq(): method terminated unexpectedly ERROR: <core> [core/parser/parse_cseq.c:92]: parse_cseq(): bad cseq ERROR: <core> [core/parser/msg_parser.c:144]: get_hdr_field(): bad cseq ERROR: <core> [core/parser/msg_parser.c:337]: parse_headers(): bad header field [CSeq: 1 OPTIONS] WARNING: <core> [core/receive.c:319]: receive_msg(): parsing relevant headers failed ERROR: <core> [core/parser/parse_cseq.c:56]: parse_cseq(): method terminated unexpectedly ERROR: <core> [core/parser/parse_cseq.c:92]: parse_cseq(): bad cseq ERROR: <core> [core/parser/msg_parser.c:144]: get_hdr_field(): bad cseq ERROR: <core> [core/parser/msg_parser.c:337]: parse_headers(): bad header field [CSeq: 1 OPTIONS] ERROR: pv [pv_core.c:1893]: pv_get_hdr(): error parsing headers ERROR: {1 <null> monitoring(a)13.236.91.139} <core> [core/parser/parse_cseq.c:56]: parse_cseq(): method terminated unexpectedly ERROR: {1 <null> monitoring(a)13.236.91.139} <core> [core/parser/parse_cseq.c:92]: parse_cseq(): bad cseq ERROR: {1 <null> monitoring(a)13.236.91.139} <core> [core/parser/msg_parser.c:144]: get_hdr_field(): bad cseq ERROR: {1 <null> monitoring(a)13.236.91.139} <core> [core/parser/msg_parser.c:337]: parse_headers(): bad header field [CSeq: 1 OPTIONS] ERROR: {1 <null> monitoring(a)13.236.91.139} <core> [core/parser/parse_cseq.c:56]: parse_cseq(): method terminated unexpectedly ERROR: {1 <null> monitoring(a)13.236.91.139} <core> [core/parser/parse_cseq.c:92]: parse_cseq(): bad cseq ERROR: {1 <null> monitoring(a)13.236.91.139} <core> [core/parser/msg_parser.c:144]: get_hdr_field(): bad cseq ERROR: {1 <null> monitoring(a)13.236.91.139} <core> [core/parser/msg_parser.c:337]: parse_headers(): bad header field [CSeq: 1 OPTIONS] ERROR: {1 <null> monitoring(a)13.236.91.139} maxfwd [mf_funcs.c:51]: is_maxfwd_present(): parsing MAX_FORWARD header failed!

It appears parse_cseq() is expecting a higher cseq, or more headers? I’ve looked at another OPTIONS message we get regularly from one of our upstream, and it’s almost identical to this one. Can anyone point me the right way here? Thanks! Andrew

Kamailio IMS setup - user online - unable to call
by Jack R 12 Sep '19

12 Sep '19

Hi All, We have installed Kamailio as IMS setup pcscf icscf scscf - 3 instances running on Ubuntu.. Users alice and bob are online however unable to call. When we check the logs the FHoSS is hunting for values in sh_subscription table for alice / bob user. Can you please share: 1. A sample database table values to be inserted across all tables in FHoSS helpful for the call and 2, Maybe, if possible, some description to understand table structures/ importance of fields of FHoSS. Thanks and Regards, Jack.

Can't connect to db

Hi all, I just installed kamailio 5.2.4 on two separate aws instances in two separate regions. Both regions uses the same configuration template and share the same db in AWS RDS. The issue I see is this: - SJO location was able to launch fine without any issues. - ASH location could not start up kamailio process due to db connection failure: Sep 10 21:24:13 ashmainkama51 /usr/sbin/kamailio[8043]: ERROR: db_mysql [km_my_con.c:139]: db_mysql_new_connection(): driver error: Too many connections Sep 10 21:24:13 ashmainkama51 /usr/sbin/kamailio[8043]: ERROR: <core> [db.c:319]: db_do_init2(): could not add connection to the pool Sep 10 21:24:13 ashmainkama51 /usr/sbin/kamailio[8045]: ERROR: db_mysql [km_my_con.c:139]: db_mysql_new_connection(): driver error: Too many connections Sep 10 21:24:13 ashmainkama51 /usr/sbin/kamailio[8045]: ERROR: <core> [db.c:319]: db_do_init2(): could not add connection to the pool Sep 10 21:24:13 ashmainkama51 /usr/sbin/kamailio[8045]: ERROR: carrierroute [db_carrierroute.c:141]: carrierroute_db_open(): can't connect to database.

LCR lcr_id short or int?
by Grant Bagdasarian 10 Sep '19

10 Sep '19

Hello, The database tables definition for 5.2.x mentions the lcr_id parameter being of unsigned short type, while in the code I only see definitions of type int. Is it safe to assume the parameter is of type int, so the database column can also be set to an integer type? Regards, Grant

Share variable into reply route.
by Zhan Bazarov 09 Sep '19

09 Sep '19

Hello, we ran into a trouble with sharing variable into reply route... We are going to match asterisk's uniqueid with rtpengine records like this: route[from_asterisk]{ $var(UniqueId)=$hdr(X-UniqueId); $var(rtp_flags) = $var(rtp_flags) + " label={uid:$var(UniqueId),stream:outgoing} record-call=on"; rtpengine_manage($var(rtp_flags)); } reply_route[from_pstn]{ rtpengine_manage("replace-origin replace-session-connection ICE=remove RTP/AVP rtcp-mux-demux label={uid:$var(UniqueId),stream:outgoing"); } and it doesn't work... The one possible way what we found its using $shv instead of $var... But its unsecure way, cuz it may confus our bussines logic... Do you have any idea how to implement this? Many thanks!

Error Users - 604 Does not exist anywhere - HSS User Unknown
by Jack R 08 Sep '19

08 Sep '19

Hi, We have installed Kamailio as IMS setup pcscf icscf scscf - 3 instances running on Ubuntu.. 1. 2 Sip client registers successfully (shows Online) as 'bob(a)net1.test' and 'alice(a)net1.test' 2. When we check server logs: Invite request shows 'bob@IP address' i.e. ' bob(a)10.0.0.10' 3. However, in HSS it is registered as 'bob(a)net1.test'. 4. When the request from SCSCF goes to ISCSF it gives Error: Users - 604 Does not exist anywhere - HSS User Unknown. As it compares 'bob(a)10.0.0.10' with 'bob(a)net1.test'. Please help and advise how everywhere (SCSCF, PCSCF) during query/comparisons it can take 'bob(a)net1.test' and not 'bob(a)10.0.0.10' Thanks and Regards, Jack.

Kamailio - PfSense Firewall - inbound/outbound rules
by Youssef Boujraf 06 Sep '19

06 Sep '19

Dear All, I am evaluating the kamailio proxy 5.2 server with rtpproxy on an internal network. Everything are ok. Now, I would like to evalute Kamailio proxy from outside (internet) but I have some difficulties to setup my PfSense firewall to enable inbound & outbound rules, network settings and kamailio.cfg. The issues are : Setup correctly Network files : * /etc/hostname 127.0.0.1 localhost ip_private codecsip.mydomain codecsip ip_public codecsip.mydomain codecsip * /etc/hosts file codesip * dns * /etc/resolv.conf nameserver 8.8.8.8Setup /etc/kamailio/kamailio.cfg :#!define WITH_MYSQL #!define WITH_AUTH #!define WITH_USRLOCDB #!define WITH_NAT #!define WITH_TLS /* uncomment the next line to disable the auto discovery of local aliases based on reverse DNS on IPs (default on) */ #auto_aliases=no /* add local domain aliases */ alias="codecsip.mydomain" #!ifdef WITH_NAT # ----- rtpproxy params ----- # modparam("rtpproxy", "rtpproxy_sock", "udp:127.0.0.1:7722") modparam("rtpproxy", "rtpproxy_sock", "unix:/var/run/rtpproxy/rtpproxy.sock") Setup etc/default/rtpproxy : CONTROL_SOCK=udp:127.0.0.1:7722 EXTRA_OPTS="-l <IP-address>" Where <IP-address> is the external IP address of your host. Regarding the firewall rules, it will be great to identify which rules I need to create : Inbound and outbound rules and NAT 1:1 ? If anyone have any information it could be great Best regards, Youssef

Kamailio HA
by Christian Attanasio 06 Sep '19

06 Sep '19

Hi everyone I use kamailio 5.1 with rtpengine and I would like to set up a simple warm standby or hot standby system for my sip server. on the web I found various discussions and posts that led me to deepen them the dispatcher, dmq, dmq_usrloc, db_cluster and p_usrloc modules. now, though, I'm a little confused: what approach do you recommend for this system? I thought of using two identical servers: Kam01 10.10.10.2 Kam02 10.10.10.3 Hostname cluster.mydomain.com each with its own mariadb and implementing data replication (with the dmq module? Or db_cluster and sqlops?). in this scenario is it necessary to also use the dispatcher module or implement a high available system with keepalives and floating ip? thanks, Christian

Kamalio & Asterisk integration erroneous behavior, setup issue
by Aristeidis Tsitras 05 Sep '19

05 Sep '19

new to the area and trying to setup Kamailio with Asterisk in a single machine. All users will register to Kamailio's port and in case of need for media, it will be forwarded to Asterisk, that is my intention. All of my work is based on the following link https://kb.asipto.com/asterisk:realtime:kamailio-4.0.x-asterisk-11.3.0-astdb. Here is what i have done: - Debian 8, 64 bit machine with mysql and odbc - *root@kamast: ~ $ lsb_release -a No LSB modules are available. Distributor ID: Debian Description: Debian GNU/Linux 8.11 (jessie) Release: 8.11 Codename: jessie root@kamast: ~ $ uname -a Linux kamast 3.16.0-10-amd64 #1 SMP Debian 3.16.72-1 (2019-08-13) x86_64 GNU/Linux root@kamast: ~ $ * - Kamailio 5.2 installed from Kamailio's deb repository - Asterisk 13LTS installed from source - Used the same passwords such as kamailiorw and asterisk_password, since this is a test system, for proof of concept. I did import to the mysql>asterisk database 3 users 2200, 2201 and 2202. Then created in sip.conf the same 3 users with the same credentials. Then on 3 PCs i used softphones (Jitsi, Zoiper) and registered each account to a softphone. Problems: - Cannot see the users in the Asterisk's cli, sip show peers - I can see users only in Kamailio with kamctl ul show - A call between the extensions goes to voicemail. It never reaches the other destination eg 2200 calls 2201 and in Asterisk's console i am getting a message that 2201 is absent and it goes to voicemail. The same with any other extension. Attached you can find: 1. Kamailio.cfg 2. Asterisk's sip.conf 3. Asterisk's extension.conf 4. The import that i have done to mysql for the user creation. I would appreciate if someone could point me to the error and help me fix it please?

$Au being set to $fu instead of $fU
by Joel Serrano 05 Sep '19

05 Sep '19

Hi, Testing on latest master deb nightly build from last night I've noticed that when $au is not available, $Au is being set to $fu (uri) instead of $fU (username). Docs: https://www.kamailio.org/wiki/cookbooks/devel/pseudovariables ... $Au - Acc username: username for accounting purposes. It's a selective pseudo variable (inherited from acc module). It returns auth username ($au) if exists or From username ($fU) otherwise. ... I have the following log in several places in a test box: xlog("L_NOTICE", "[DEBUG] Au=$Au au=$au aU=$aU fU=$fU fu=$fu - \n"); And when I run through them (on both request and reply routes) I get the following: Aug 8 14:37:43 csbc01 csbc[9478]: NOTICE: {1 21564 REGISTER d8df9be1-1702e20b(a)A.B.C.D} <script>: [DEBUG] Au=1002366(a)some.domain au=<null> aU=<null> fU=1002366 fu=sip:1002366@some.domain - Aug 8 14:37:43 csbc01 csbc[9479]: NOTICE: {1 21565 REGISTER d8df9be1-1702e20b(a)A.B.C.D} <script>: [DEBUG] Au=1002366(a)some.domain au=1002366 aU=1002366 fU=1002366 fu=sip:1002366@some.domain - Aug 8 14:37:43 csbc01 csbc[9484]: NOTICE: {2 21565 REGISTER d8df9be1-1702e20b(a)A.B.C.D} <script>: [DEBUG] Au=1002366(a)some.domain au=<null> aU=<null> fU=1002366 fu=sip:1002366@some.domain - Those 3 logs belong to the same flow from different places in the config script. I would expect $Au to never have a "@some.domain" in it, so I assume in some place the replacement is not being done with $fU but with $fu. @Devs: I'm happy to create a GH issue for tracking etc if required, please let me know! Cheers, Joel.

How to detect miss call and accomplished call
by Anuran Barman 05 Sep '19

05 Sep '19

Hi, I want to show call logs in my SIP app. How can I do this with Kamailio? I want to do it from the *kamailio.cfg *file. Is it possible to do it from where? I guess Dialog module should be used for this, but can not figure out how to do it. I want minimalist feature like who call whom with timestamp, thats all. How can I do this?

There are 6 new modules and many other enhancements to existing components in git master branch, also during the last irc devel meeting it was proposed to freeze after summer holidays. At this moment I would propose Wednesday, September 4, 2019 to freeze the development. Then the release should be about one month later, after testing interval. In case there are people willing a bit more time for development, we can freeze one week later, September 11, or another date -- your suggestions here.

Using Kamailio IMS for making a call
by supreeth herle 04 Sep '19

04 Sep '19

Hello Everyone, I have successfully setup a VM in OpenStack with Kamailio IMS, rtpengine and FoHSS using the instructions mentioned in the guide which i wrote (attached to this mail), all running in the machine. I am using the existing alice and bob IMPUs created in FoHSS. But, when I try to call each other the call doesnt go through and I observe in the wireshark traces that S-CSCF is replying to I-CSCF that "403, Forbidden - Domain not served". Can somebody please tell me do I need any additional components to make a call or am i missing some configuration? It would be great if someone can help me troubleshooting this issue. I have attached the pcap file for your reference. Many thanks in advance. Regards, Supreeth

Kamailio stops processing requests over UDP
by Juha Heinanen 04 Sep '19

04 Sep '19

I'm returning to an old issue, where Kamailio stops processing incoming requests. Now it turned out that only requests over UDP are not processed. Requests over TCP work fine. Debug log doesn't show anything about the requests over UDP, but wireshark sees them coming. core.ps shows that main process - attendant and all udp receiver processes are alive. Any ideas what could cause Kamailio (5.2 version) to stop processing requests over UDP? What additional info should I try to get? -- Juha

Hello Group - I have a "challenge"
by Kevin Greene 04 Sep '19

04 Sep '19

I recently did the upgrade from v4.4 to 5.2 (via Yum). When starting Kamailio, I get these three errors. Not sure if they are related or not but I do not think so. Have spent a lot of time searching on Google for the answer and have not found the solution. [root@ids kamailio]# kamctl restart INFO: Stopping Kamailio : INFO: stopped INFO: Starting Kamailio : INFO: started (pid: 44608) [root@ids kamailio]# tail -f /var/log/sipserver.log Sep 4 00:39:06 ids /usr/sbin/kamailio[44608]: ERROR: <core> [core/pvapi.c:1119]: pv_parse_spec2(): wrong char [t/116] in [$mt] at [2 (0)] Sep 4 00:39:06 ids /usr/sbin/kamailio[44608]: ERROR: <core> [core/dprint.c:451]: log_prefix_init(): wrong format[{$mt $hdr(CSeq) $ci} ] Sep 4 00:39:06 ids /usr/sbin/kamailio[44626]: ERROR: <core> [core/receive.c:319]: receive_msg(): no request_route {...} and no other config routing engine registered The last error is repeated many times (each time a remote user tries to connect I think). I can send any additional files if needed. Thanks. I am burning out on this upgrade. Kevin

Unexpected BYEs from dialog module
by Alex Balashov 03 Sep '19

03 Sep '19

Hi, I am running 4.3.5:1b0c0a, which I am aware is an EOL'd release train, and have a problem with the dialog module I am baffled by. On many calls - I can't find any correlation to particular kinds of endpoints - I see spoofed BYEs come out of Kamailio after a minute and a half, as if the call had hit a dialog timeout or the dialog module's dead peer detection (OPTIONS pinging) kicked it out. The thing is, neither of those explanations seem to be borne out by the parameters of the calls under investigation. The dialog timeout on these calls is set to 7200, and the dialog keepalives aren't enabled in either direction. If they were, it'd be logged. Calls that are terminated in this manner also see the following log message: WARNING: dialog [dlg_req_within.c:214]: bye_reply_cb(): inconsitent dlg timer data on dlg 0x7f9997317e48 [3390:9644] with clid '1996679936_133218050(a)x.x.x.x' and tags '2bb17663-co4006-INS001' 'as7925780d' But I don't think this is unusual for a dialog-spoofed BYE; presumably this is due to a 200 OK for the BYE from both ends. So anyway, I am trying to track down anything else that could inadvertently cause dialog to hang up calls relatively quickly in that release, or inadvertently set the dialog timeout parameter to something lower than is apparent from the logging and the config. If anyone has any pointers, that would not go unappreciated!

Issue with uac_replace
by David Costa 01 Sep '19

01 Sep '19

Greetings, I have a Kamailio proxy with uac_replace for To and From Headers. So far everything has worked correctly. However, I now have a client who encodes my Calling Number too and I'm getting some issues in the restore mechanics. I have the restore setup as "auto" and it's info is stored in "vsf" and "vst" parameters of Record-Route. On replies sent by my client I have the following Record-Route and From Header (Note : My Kamailio has two IPs which makes it insert two RR headers ): Record-Route: <sip:xxx.xxx.xxx.xxx;r2=on;lr;ftag=99A730303736313103579CC4;tbk_i=1_2_Y;tbk_ o=128_11_Y;vsf=AAAAABgGBAMDAAUBBQAJDndyAwMcHwIdHQsWHwUDNw--;vst=AAAAABgGBAMH DQgJDQECA3RyAwMcHwIdGgQeHAIFAnVzZXI9cGhvbmU-;did=f74.78e2> Record-Route: <sip:xxx.xxx.xxx.xxx;r2=on;lr;ftag=99A730303736313103579CC4;tbk_i=1_2_Y;tbk_ o=128_11_Y;vsf=AAAAABgGBAMDAAUBBQAJDndyAwMcHwIdHQsWHwUDNw--;vst=AAAAABgGBAMH DQgJDQECA3RyAwMcHwIdGgQeHAIFAnVzZXI9cGhvbmU-;did=f74.78e2> From: "+351411110097" <sip:I2116446I_500@xxx.xxx.xxx.xxx>;tag=99A730303736313103579CC4 In this case the restore is done correctly When the client sends me a BYE request I have the following Route Header and To Header Route : <sip:xxx.xxx.xxx.xxx;r2=on;lr;ftag=99A730303736313103579CC4;tbk_i=1_2_Y;tbk_ o=128_11_Y;vsf=AAAAABgGBAMDAAUBBQAJDndyAwMcHwIdHQsWHwUDNw--;vst=AAAAABgGBAMH DQgJDQECA3RyAwMcHwIdGgQeHAIFAnVzZXI9cGhvbmU-;did=f74.78e2>,<sip:xxx.xxx.xxx. xxx;r2=on;lr;ftag=99A730303736313103579CC4;tbk_i=1_2_Y;tbk_o=128_11_Y;vsf=AA AAABgGBAMDAAUBBQAJDndyAwMcHwIdHQsWHwUDNw--;vst=AAAAABgGBAMHDQgJDQECA3RyAwMcH wIdGgQeHAIFAnVzZXI9cGhvbmU-;did=f74.78e2> To : "+351411110097" <sip:I2116446I_500@xxx.xxx.xxx.xxx>;tag=99A730303736313103579CC4 In this scenario, the To after restore is : To :"+351411110097" <sip:Q4525417L_<>Gxxx.xxx.xxx.xxx>;tag=99A730303736313103579CC4, which throws an internal error on Kamailio about bad URI and also makes our MediaGateway reply with a "Bad Request". Can this error be caused by the restore of the uac_replace mechanics? Both Record Route URIs are on different headers while the both Route URIs are on the same Route header. Can this be the reason? If you need more information please let me know. Best Regards David Costa

Re: [SR-Users] controlling presence with new module `pua_json`
by Henning Westerholt 30 Aug '19

30 Aug '19

Hello Bill, (please keep the list in CC) yes, this seems to be the case. Just looked briefly to the code, it does an assignment in some cases. E.g. if no Presentity* data is given it will just use the From* information. And then it should later output an error from pua_json_update_presentity(..) if there is not the necessary data. Do you see any error message like this? Another idea - does it works if you add more "missing" data in the curl requests?

Info: Upgrading kamcli to work with Python3
by Daniel-Constantin Mierla 30 Aug '19

30 Aug '19

Hello, with the perspective that Python2 is going to be removed from the major Linux distributes starting with the beginning of next year, the work to upgrade kamcli to run with Python3 has been started. >From now on, master branch of kamcli is expected to work only with Python3: * https://github.com/kamailio/kamcli There is still work to be done to upgrade all the code, but any use of it should be done with Python3 and eventual issues to be filed on bug tracker. Of course, pull requests are welcome as always! Who wants to use the version for Python2 has to use the code from git branch v1.2-python2. That branch is probably not going to receive any new feature, it will be kept for use with older systems (as well as a running option during the upgrade period to Python3).

Kamailio 5.0.8 | authentification issue only with TCP/TLS
by Laurent Schweizer 29 Aug '19

29 Aug '19

Dear all, I have a kamailio running in version 5.0.8 and since fee weeks we have an issue with different users connected in TCP or TLS, sometimes authorization like for REGISTER are rejected and after a moment (can be few minute or hours) it work again and of course no change was done in the password .... We see this issue with different device, snom swyx, ... and on UDP we have no issue. I can see that when the Register is rejected it's with the error -2, so wrong password... # Authentication route route[AUTH] { if (is_method("REGISTER")) { # authenticate requests if (!auth_check("$fd", "subscriber", "1")) { switch($retcode) { case -1: sl_send_reply("503","Service not available"); exit; case -2: xlog("L_WARN", "auth error -2 username $au - src ip: $si \n"); auth_challenge("$fd", "0"); exit; I have attached an example of a trace where we can see a first REGISTER accepted and less than 2 minutes after a new one is rejected. ( in between they is a REGISTER without any Authorization header) Any idea ? BR Laurent

Hi, I have some issue and dont have enought knowledge to fix it. I have simple infrastructure.

Disable GW's on runtime
by Duarte Rocha 28 Aug '19

28 Aug '19

Greetings, I have two Kamailio's working on a HA scenario. Both Kamailio's have DB replication and each machine has one HA IP. In order to set this up, i have every GW on the DB duplicated, one with Socket IPA and another with socket IPB. I have both GWs in a active state configurated in the replicated DB. They also both have the same URI and the same group id Example : GW1 : Socket = IPA ; GroupID = 1 ; Uri = sip:1.1.1.1:5060 GW2 : Socket = IPB ; GroupID = 1 ; Uri = sip:1.1.1.1:5060 In order to avoid errors, i want to disable on runtime the GWs that have a socket that doesn't belong, at the moment, to that machine (GW with Socket IPB on machine with IPA). To do that i would use the dispatcher.set_state, however it works with group id and address, which in this case it is the same. Is there other method to disable the GWs on runtime using other arguments like duid or socket ? I thought about using probing for this, since it will disable automatically the GWs with non-existent socket, but not all my clients support probing, so it isn't feasible. Thanks in advance

UAC ha1 password
by Alexandru Covalschi 28 Aug '19

28 Aug '19

Hello, I'm trying to make Kamailio to SIP register on a remote server. However storing plaintext password looks very unsecure. Is there a possibility to store password for uac module using ha1 hash instead of the plaintext password? I see there's a row for it in the database, but in the source code it's not used and it seems i can't neither use it in db neither set up in-memory as avp. Maybe there's a workaround to directly access the in-memory uac registration htable? ________________________________ Regards, Alexandru Covalschi VoIP Engineer and System Administrator tel: +37367367850

[tm-local-request] usage
by Duarte Rocha 28 Aug '19

28 Aug '19

Greetings, Does "event_route[tm:local-request]" works like onsend route ? I'm having some problems and i'm using local-request to debug and i found this on the documentation : "Executed after the tm module has sent a local generated, transaction stateful request." I'm logging all the requests that go through this route. Is this really the last place before kamailio send the request? If the request is logged here, is there anything more in kamailio that can stop the request (pipelimit, etc) ? If a packet gets logged on this route does that mean that it was already sent? Best Regards, Duarte Rocha

Dispatcher - FQDN with multiple IPs
by Sergiu Pojoga 27 Aug '19

Hi ppl, The problem I'm facing is that function *ds_is_from_list* seems to return false when a gateway's address is a FQDN that resolves into multiple IP addresses (I'm talking about A records), consequently in-dialog requests like BYE and re-Invites get blocked since they don't pass the *ds_is_from_list* validation. Am I missing some parameter or something? Thanks, --Sergiu

RFC: about sl and tm local-response event routes
by Daniel-Constantin Mierla 27 Aug '19

27 Aug '19

Hello, just discovered what I consider to be an inconsistency in naming and behaviour for event_route blocks for local-request and local-response and starting a discussion here to see how to move on. The event_route[tm:local-request] is executed before sending there local generated request out (allowing also to change its content, drop, etc...). This event route is quite popular event route used when the local generated requests need to be checked or updates. The event_route[tm:local-response] is executed after the response is sent out, obviously no possibility to change anymore the content. I haven't checked the code for event_route[sl:local-response], but based on commit message should be the same. I haven't used the local-response so far at all, today after a discussion on sr-users I wanted to enable kemi callback for tm:local-response and I noticed that behaviour in the code, even I expected to be like local-request (before sending out). I am not sure how much used are the event routes for tm:local-response and sl:local-response, I haven't seen any questions about them so far on mailing lists, that's why I am asking here if would make sense to rename them like tm:local-response-sent and sl:local-response-sent to properly reflect when they are executed. I am expecting that they are very few used so far, so no big head ache with upgrades and bringing some consistency around (this change to be part of next major release). It can stay like now with proper documentation, however in the future if one want and event route for local responses before being sent out, there will be more confusion, imo ...

exit stop procesing or not after a conditional? based on "exit" core docs seems does not explain behaviour
by PICCORO McKAY Lenz 26 Aug '19

26 Aug '19

in my kamailio-asterisk integration i have a exit after the authentication logic, BUT; there's another conditional after the "exit" sentence, so my ask, if there's a exit in that piece of code .. that next conditional will not be executed? Docs seems said "stop execution of script" so all the rest of the logic in file will not be routed? The documentation seems does not explain in good behavior what happened or the kamailio-asterisk wiki page does not have good explanations for that! it's that an error? https://www.kamailio.org/wiki/cookbooks/4.3.x/core#exit - - ``` if (from_uri==myself) {#!ifdef WITH_ASTERISK if (!proxy_authorize("$fd", "sipusers")) {#!else if (!proxy_authorize("$fd", "subscriber")) {#!endif proxy_challenge("$fd", "0"); exit; } if (is_method("PUBLISH")) { if ($au!=$tU) { sl_send_reply("403","Forbidden auth ID"); exit; } } else { if ($au!=$fU) { sl_send_reply("403","Forbidden auth ID"); exit; } } consume_credentials(); # caller authenticated } else { # caller is not local subscriber, then check if it calls # a local destination, otherwise deny, not an open relay here if (!uri==myself) { sl_send_reply("403","Not relaying"); exit; } } } #!endif return; } ``` 8:52 am Lenz McKAY Gerardo (PICCORO) http://qgqlochekone.blogspot.com

reply cannot be forwarded - no 2nd via
by Ryan McEvoy 25 Aug '19

25 Aug '19

Hello, I have been having an issue using kamailio to load balance to a SIP/MRCP server. I believe that the issue actually lies with the reply being sent from the final recipient, but I wanted to be sure that I understood the problem and to see if there were any possible solutions within Kamailio. I am using the dispatcher module to dispatch SIP INVITES to media resources, in this case I am just using a single host in a single dispatcher group. The configuration that I have has worked just fine for other SIP/MRCP servers, which is why I think the issue is with this target in particular. The INVITE is routed correctly and contains the headers that it should. The invite comes originally from a Freeswitch, arrives at Kamailio, who should then dispatch to a host in the group. x.x.x.x:4901 is Kamailio x.x.x.x:8090 is Freeswitch y.y.y.y:8000 is the final target This is the invite, as received by the final target after dispatched via Kamailio INVITE sip: x.x.x.x:4901 SIP/2.0 Record-Route: <sip: x.x.x.x:4901;transport=tcp;lr> Via: SIP/2.0/TCP x.x.x.x:4901;branch=z9hG4bK3a9a.7f9a4b588cd75108cfea9a2bd9ffa829.0;i=3 Via: SIP/2.0/TCP x.x.x.x:8090;branch=z9hG4bKStXp06Sv7jU7S Max-Forwards: 69 From: <sip: x.x.x.x:8090>;tag=4gHgNcNUDjvFQ To: <sip: x.x.x.x:4901> Call-ID: 6f2a0e9c-3f9e-1238-2aa9-005056854777 CSeq: 8692231 INVITE User-Agent: tts Allow: INVITE, ACK, BYE, CANCEL, OPTIONS, PRACK, MESSAGE, SUBSCRIBE, NOTIFY, REFER, UPDATE Supported: timer, 100rel Content-Type: application/sdp Content-Disposition: session Content-Length: 281 v=0 o=IPSoft 3367790083977298880 2789991278648035021 IN IP4 x.x.x.x s=- c=IN IP4 x.x.x.x t=0 0 m=application 9 TCP/MRCPv2 1 a=setup:active a=connection:existing a=resource:speechsynth a=cmid:1 m=audio 32038 RTP/AVP 0 a=rtpmap:0 PCMU/8000 a=recvonly a=mid:1 The reply that the server sends back appears to be missing a second Via header, which is preventing Kamailio for routing it correctly (based on the error message from core/forward.c) This is the reply sent by the target destination SIP/2.0 200 OK Via: SIP/2.0/TCP x.x.x.x:8090;branch=z9hG4bKStXp06Sv7jU7S To: <sip: x.x.x.x:4901>;tag=ndszib3k From: <sip: x.x.x.x:8090>;tag=4gHgNcNUDjvFQ Call-ID: 6f2a0e9c-3f9e-1238-2aa9-005056854777 CSeq: 8692231 INVITE Contact: "Voiceware MRCP Server" <sip:vwmrcp@ y.y.y.y:8000;transport=tcp> Content-Type: application/sdp Content-Length: 324 v=0 o=- 1566492047 1566492047 IN IP4 y.y.y.y s=Voiceware MRCP Server 2.15.0.7.

If so, is there anything else that can be done in Kamailio to handle this, or is this mrcp server simply not complying properly with SIP? There’s no funky natting between these hosts or anything like that. Thanks in advance!

When set_rtpengine_set() is called with two parameters before rtpengine_offer(), e.g. set_rtpengine_set("1", "2"); rtpengine_offer(); it was not clear to me from rtpengine README, if the sets need to reversed when set_rtpengine_set() is called before rtpengine_answer(), i.e., set_rtpengine_set("2", "1"); rtpengine_answer(); or can the order of the sets be the same as it was in case of rtpengine_offer()? -- Juha

Dealing with optional SRTP
by Mark Boyce 24 Aug '19

24 Aug '19

Hi all (Using Kamailio + RTPEngine, both current stable versions) Just wondering what current best practice is for dealing with “optional SRTP” such as those generated by Yealink devices. (I know this breaks the RFC but lots of things seem to use this method.) Where the device SDP message looks like; m=audio 50004 RTP/AVP 8 97 101 a=crypto:1 AES_CM_128_HMAC_SHA1_80 inline:uhJOWOXPuzMeBmrbx2wAKohuveAvZeMEJTzfE7GT a=crypto:2 AES_CM_128_HMAC_SHA1_32 inline:yF+EhR3RtxSDCGtLCnEAl3Zrdut4b8cfFQP+hFqf An unencrypted RTP/AVP media line but with crypto lines showing that the device will support SRTP encryption but it is not mandatory. The system of offer SRTP and try and catch on not supported/acceptable here fail feels a little clumsy and relies on how gracefully the device sends “not acceptable here”. I’m wondering if I just short cut it and say that if a device offers a acceptable crypto line then Kamailio sends back a SAVP response. Naturally this question is then closely followed by how to do optional SRTP invites originating from Kamailio without just directly manipulating lines? Feels like there should be an RTPEngine setting for Optional? RTP/AVP+SAVP ? Thoughts? Mark

Kamailio as an Outbound Proxy - Strange Sip Flow
by Diogo Hartmann 23 Aug '19

23 Aug '19

Hello Kamailio experts, We have a Kamailio as outbound proxy in front of Asterisks PjSIP. There is a strange behavior after 200 OK: - ACK comes from Asterisk Public IP instead of coming from the internal IP address. - BYE can not be processed (404 not here) SNGREP print attached. Has anyone ever experienced this? I can provide more information if needed, just let me know what info. Thanks! Diogo Hartmann

Hi all, I am totally new with Kamailio but i have needs to build small cluster of Asterisk. Right now I could succesfully register to asterisk via kamailio and even make a call to hear tt-weasels but Asterisk cant close call My infrastructure diagram is here http://www.asciidraw.com/#Draw6816041626716434245/903175935 This is what probably I need is to know how to tell to Asterisk that send BYE to private IP of Kamailio instead public IP of Kamailio, am I right ?

TCP: Strange Device Behaviour
by Carsten Bock 23 Aug '19

23 Aug '19

Hi, I have a device here, which does some sort of strange things: I have SIP Message, e.g. with a length of 1100 Bytes and the devices adds "0" to the end to meet the MTU of the network (for a single TCP frame), some sort of TCP padding. The following TCP Frame contains only the next message. Looking at the trace in Wireshark, sngrep or similar, all of them try to re-assemble the next message in the TCP stream, but however don't decode them as SIP due to to first couple of zero's in the message. Looking at Kamailio, it seems not to have any issues with this and decodes/parses the message properly (they show up on Homer properly); however it also forwards the message INCLUDING the first couple of zero's even on UDP. To make it complitely irritating, the phone itself would ignore such packets, if we would forward them to the phone with starting zeros. Has anyone seen anything like this and is it standards-compliant? Any proper and easy way to get rid of the starting "zero's" from a message before forwarding these messages? I could always "hack" something into src/core/tcp_read.c, but I wonder if there is already a proper way? Any ideas anyone?

About STIR/SHAKEN - Caller Identity
by Daniel-Constantin Mierla 23 Aug '19

23 Aug '19

Hello, at couple of events I participated during the past few months, I was asked about support of STIR/SHAKEN (caller identity authentication/verification), which is a hot topic these days at least in USA, aiming to combat "fraudulent" robo-calling. Therefore I thought of share some details with everyone in the community about the state in Kamailio, writing to both devs and users, the information being relevant for everyone. We already have the (related) module named auth_identity, available since 2008 (iirc): - https://www.kamailio.org/docs/modules/stable/modules/auth_identity.html But it implements the previous iteration of the specs for caller identity, respectively RFC 4474: - https://tools.ietf.org/html/rfc4474 However, that RFC is obsoleted by 8224 (the latest core specs for STIR/SHAKEN): - https://tools.ietf.org/html/rfc8224 Then, there are also RFCs 8225 and 8226 to add to the core specs. Should anyone be interested to implement STIR/SHAKEN specs in a modules, I would suggest to start from auth_identity -- might not be much work to update it to become conform with latest specs (a new module can be created, of course, even when starting from auth_identity). However, these specs are about signing the SIP request (the INVITE) with special PKI certificate. It can be done easily with embedded scripts such as Lua or Python (inline execution in native kamailio.cfg or using kemi scripts). At Kamailio World 2019, one of the participants I discussed with told me they already implemented using Lua. That's it for a starting point, if anyone wants to discuss more, just reply to sr-users and add your comments or ask the questions. If someone wants to go ahead and work on a C module, announce yourself to avoid duplicate work of others, and use sr-dev if you need assistance on module development.

basic Kamailio frontend to Asterisk
by Travis Ryan 22 Aug '19

22 Aug '19

All, I would like to use Kamailio as a frontend/proxy for an asterisk machine/cluster. I'm very well versed in Asterisk, but VERY noob to Kamailio. I've watched so many Kamailio presentations and feel like I've scoured the web for any article that could help me. There is alot out there, but I'm not finding my exact situation. I believe I understand the dispatcher stuff that I'll need down the road, but I'm having issues understanding the setup of my SIP trunk and Kamailio. I used UAC to setup the trunk connection in Kamailio and it sort of worked. I'm not sure what I do for Asterisk. I'd suspect that in this situation Kamailio would handle the registration and trunk connection for me. What role is Kamailio to my Asterisk? Just an Outbound proxy? Do I need to still register the trunk from each Asterisk box "thru" the Kamailio proxy, etc? Also, I'm merely accepting outside calls and then validating the caller and bridging them back out to the PSTN, so I don't have any local SIP clients, etc., so no need to register the sip devices, etc. Thanks! Travis

Slowly increasing PKG memory usage
by Andrew White 20 Aug '19

20 Aug '19

Hi all, I had a Kamailio crash the other day, and some debugging showed I ran out of PKG memory. Since then I’ve run a simple bash script to compile the amount of memory used by all child processes, effective /usr/local/sbin/kamcmd pkg.stats | grep real_used summed together. I’ve graphed out the data, and there’s a clear growth of PKG memory going on, mostly increasing during our busier daytime hours. https://i.imgur.com/UTzx2k1.png Based on this, I suspect either a module loaded or something within my app_ruby conf is leaking memory. I’ve been reading through https://www.kamailio.org/wiki/tutorials/troubleshooting/memory <https://www.kamailio.org/wiki/tutorials/troubleshooting/memory>, but I’m a bit nervous, as I’m not really a C/deep memory type of guy. I can see a GDB script I can attach to Kamailio, but is that going to use significant resources to run or impact the running process? Is there a newer/better/alternative way to do this, and to help me break this down? Thanks! Andrew

Replacing Caller ID
by Pete Kay 18 Aug '19

18 Aug '19

Hi Could anyone tell me if there is a module for replacing the caller ID in the SIP messages? I need to replace the caller ID when the call comes in and leaves Kamailio. When the egress sends back any response, I need to revert the caller ID back to its normal form. I have a long list of numbers to be used as caller-ID, and I need to keep modifying them without having to restart Kamailio. Do I need to write my own modules for maintaining the list of numbers to be used as caller-id? I am running at 2000 CPS, so I think I need to implement some sort of hash table in order for the caller id to be retrieved in round roubin fashion very quickly. Is there any modules for this purpose or I need to write a cusom one? Pete

uac_replace_from() and multiple branches
by John Quick 16 Aug '19

16 Aug '19

v5.2.3 of Kamailio. Serial forking is used to route calls to a multiple destinations as described in documentation for the TM module. Also using the DIALOG module - my script calls dlg_manage() before loading the serialised branches. I need to be able to substitute the username part of the From header and have been trying this with calls to uac_replace_from(). modparam("uac", "restore_mode", "auto") modparam("uac", "restore_dlg", 1) There is no problem if all branches use one substituted From username, in which case my script calls uac_replace_from() in the main route. uac_replace_from("sip:" + $avp(route:src) + "@" + $fd); However, I may need to substitute a different value for each branch. Can this be done? I tried moving the call to uac_replace_from() into the branch route, but then I get an error when the final BYE is received: ERROR: uac [replace.c:281]: replace_uri(): decline FROM replacing in sequential request in auto mode (has TO tag) Is there a simple solution to this please? Hoping I can still use UAC auto restore mode because manual restore looks quite tedious/complex. Thanks. John Quick Smartvox Limited www.smartvox.co.uk

RFC 3860 support - Kamailio is sending SUBSCRIBE back with extra Via header
by Praveen Vatti 15 Aug '19

15 Aug '19

Hi Kamailio support, Basically, I am looking for RFC3860 support - i.e., accept SUBSCRIBE for reg event and send 200OK, NOTIFY to client. With some browsing on Internet I came across Kamailio, which is supporting RFC3860. I have installed and attached is my CFG file. I am sending a SUBSCRIBE request with reg event to Kamailio and it is sending back the same request with extra Via header. Via now contains Kamailio system IP and the source of SUBSCRIBE IP. Please help me in resolving this issue. I have loaded db_mysql, dialplan, tm, sl, presence, presence_reginfo modules. Thanks, Praveen

Question regarding Dispatcher + ds_default_socket() modparam + Call-ID generation
by Joel Serrano 14 Aug '19

14 Aug '19

Hello, Simple doubt regarding dispatcher module when you have the ds_default_socket() modparam set: Say you have 2 kamailio boxes, active + passive, one shared IP via keepalived.... On the actrive node, you have dispatcher.send_ping to 1, and the passive has it set to 0. So far OK, only the active box is sending out probing OPTIONS requests, and it's using as outbound socket the virtual IP out of all the available ones (as defined with ds_default_socket() modparam) I have seen in a capture that the outbound OPTIONS look like: OPTIONS sip:190.14.203.219:5060 SIP/2.0 Via: SIP/2.0/UDP A.B.C.180 ;branch=z9hG4bK7abb.6fbaccc1000000000000000000000000.0 To: <sip:190.14.203.219:5060> From: <sip:dspinger@my.domain>;tag=e2bdd495733c59fd91487a137fccad4e-8a73 CSeq: 10 OPTIONS Call-ID: 2019f8491329c382-31419(a)A.B.C.181 Max-Forwards: 70 Content-Length: 0 A.B.C.180 -> VRRP A.B.C.181 -> Physical IP of the box My doubt is, shouldn't ds_default_socket also update the IP used to generate the Call-ID used in the OPTIONS request? Currently, I believe it's using the first defined listen= IP from config script as I switched the order the listen= are defined and I get the desired result: OPTIONS sip:186.188.220.174:5060 SIP/2.0 Via: SIP/2.0/UDP A.B.C.180 ;branch=z9hG4bKc97e.a8d9e1c2000000000000000000000000.0 To: <sip:186.188.220.174:5060> From: <sip:dspinger@my.domain>;tag=5e2e1773f812f6a7e4085c5d036e29d8-d323 CSeq: 10 OPTIONS Call-ID: 7d9a92c218fc1ba0-32111(a)A.B.C.180 Max-Forwards: 70 Content-Length: 0 Is this expected?

Kamailio/Freeswitch auth user and UserID
by Petarr Jones 14 Aug '19

14 Aug '19

Hi I am new to Kamailio and would like some guidance on linking up with Freeswitch. I have an exiting hosted Asterisk PBX that uses a combination of extension and pbx username (eg 1001-126252581276) and I want to move it over to Kamailio/Freeswitch without re-configuring the SIP phones. I have tried Freeswitch "number-alias" but it does not seem like a good fit due to things like BLF not working and the added overhead etc. Is there a way to configure Kamailio to authenticate a user based on the above username and then send an extension to Freeswitch as the UserID instead, thereby separating the Kamailio authentication from the Freeswitch UserID? As I don't yet have a full understanding of the Kamailio/Freeswitch interaction, I don't know whether this will cause other issues? Thanks in advance Petarr

Re: [SR-Users] Dispatcher round-robin problems in 5.2
by JR Richardson 14 Aug '19

14 Aug '19

Hey Alex, After I recently upgraded, I had to include more response codes, 5.2 by default only 200 OK is accepted. I had some upstream carriers sending 405 and were taken off-line as a result until I added that code in modparm: modparam("dispatcher", "ds_ping_reply_codes", "class=2;code=405") Not sure if this applies to what you are doing, but my dispatcher round robin distribution acts as it did prior to upgrade to 5.2, pretty even, no anomalies with any nodes getting more calls than any other. JR JR Richardson Engineering for the Masses Chasing the Azeotrope Hi, I've got a proxy that does very basic round-robin distribution of calls to an elastic pool of servers, defined in a simple SQLite database with equal priorities. Nothing too complicated, just a vanilla `ds_select_domain("1", "4")`. The only complication is that seldom are most of the gateways enabled. Probing stuff was turned on, but didn't do quite what was desired, so it was replaced with a system that manages activation and deactivation of the gateways externally. Nevertheless, these are the left-over probing settings: modparam("dispatcher", "ds_ping_method", "OPTIONS") modparam("dispatcher", "ds_ping_from", "sip:pinger@domain") modparam("dispatcher", "ds_ping_interval", 15) modparam("dispatcher", "ds_probing_threshold", 256) modparam("dispatcher", "ds_inactive_threshold", 1) modparam("dispatcher", "ds_probing_mode", 0) After an upgrade from 5.1 to 5.2.3 (009f62), the round-robin has become extremely "sticky" and tendentious. That is to say, it directs _almost_ all calls to a single gateway -- the first gateway in the table -- though not 100%. There is also a marked tendency to send lots of consecutive calls to the same gateway, even if it's not the first one, though most of the time it is. Has anyone experienced similar upon upgrading to 5.2? Thanks much! -- Alex

Wrong Record-Route and Via header fields when TCP is used
by Leonid Fainshtein 14 Aug '19

14 Aug '19

Hi, Kamailio server has two legs that are connected to different networks. I'm using Kamailio v.5.2.3 and the "enable_double_rr" is implicitly set to "1". The leg "A" IP address is 10.159.65.1 The leg "B" IP address is 192.168.0.31 The call is initiated from 10.159.65.18 According to the "rr" module documentation, function record_route() should insert two "Record_Route" header fields when a request is accepted on one leg is should go out via the second leg. This works as expected in case of UDP protocol: INVITE sip:2000@192.168.6.106:5460;transport=UDP SIP/2.0 Record-Route: <sip:192.168.0.31;r2=on;lr;did=e2c.a191> Record-Route: <sip:10.159.65.1;r2=on;lr;did=e2c.a191> Via: SIP/2.0/UDP 192.168.0.31;branch=z9hG4bKcfa5.d64ecbd87d5315b5993c4ccf16f86537.0 Via: SIP/2.0/UDP 10.159.65.18:5060;rport=5060;branch=z9hG4bK3a9e9a4d But when the TCP protocol is used then the outbound message looks like this: INVITE sip:2005@192.168.0.178:35058;transport=tcp SIP/2.0 Record-Route: <sip:10.159.65.1;transport=tcp;lr;did=bb6.7dc1> Via: SIP/2.0/TCP 10.159.65.1;branch=z9hG4bKc85a.14afc3867dd3220826f9b9940f78168f.0;i=3 Via: SIP/2.0/TCP 10.159.65.18:5060;rport=58616;branch=z9hG4bK1469331f There are two problems there: a) only one Record-Route with leg is inserted b) the added "Via" header field contains the leg "A" IP address instead of expected leg "B" IP address (192.168.0.31). In the LAN trace I see that in reality the message was sent from leg "B". Is it a bug? Best regards, Leonid Fainshtein

I needed it in REPLY_ROUTE, and before reading the docs I tried it and got this error: Aug 12 15:52:44 csbc01 kamailio: CRITICAL: <core> [core/cfg.y:3526]: yyerror_at(): parse error in config file /etc/kamailio/csbc/reply_routes.cfg, line 27, column 71: Command cannot be used in the block#012 Aug 12 15:52:44 csbc01 kamailio[12737]: ERROR: bad config file (1 errors) But, I have this working on another setup, I compared, and my difference is that I'm running unregister() inside a route, and calling that route from reply_route, and that works (and by works, I mean it also does what it is supposed to do, which is unregister the AoR). So this doesn't work: ... onreply_route[MANAGE_REG_REPLY] { if(status=~"2[0-9][0-9]") { if(($sel(contact.expires)==0) || ($hdr(Expires)==0)){ if (unregister("location", "$sht(sipserver=>$fU::contact)")) { xlog("L_NOTICE", "[usrloc] removed user location\n"); } route(DEL_SIPSERVER); } ... But this works: ... onreply_route[MANAGE_REG_REPLY] { if(status=~"2[0-9][0-9]") { if(($sel(contact.expires)==0) || ($hdr(Expires)==0)){ route(UNREG_CUSTOMER); route(DEL_SIPSERVER); } ... ... route[UNREG_CUSTOMER] { if (unregister("location", "$sht(sipserver=>$fU::contact)")) { xlog("L_NOTICE", "[usrloc] removed user location\n"); } } ... So I'm in no-mans-land right now, docs say it's not allowed in REPLY_ROUTE, and if I try it it will fail, but if I try it inside a route, it woks (hack?). What is the correct approach here? Should unregister() be valid in reply_route (like other similar functions, for example: save()) and therefor docs should be updated and the error in the logs should also be updated, or if it's really not supported, shouldn't Kamailio not let me use it anywhere that a ends up being called from reply_route? I hope I have explained myself correctly. As always, please let me know if this should be a GH issue instead and I'll happily create it. Thanks, Joel.

Dispatcher round-robin problems in 5.2
by Alex Balashov 12 Aug '19

12 Aug '19

Hi, I've got a proxy that does very basic round-robin distribution of calls to an elastic pool of servers, defined in a simple SQLite database with equal priorities. Nothing too complicated, just a vanilla `ds_select_domain("1", "4")`. The only complication is that seldom are most of the gateways enabled. Probing stuff was turned on, but didn't do quite what was desired, so it was replaced with a system that manages activation and deactivation of the gateways externally. Nevertheless, these are the left-over probing settings: modparam("dispatcher", "ds_ping_method", "OPTIONS") modparam("dispatcher", "ds_ping_from", "sip:pinger@domain") modparam("dispatcher", "ds_ping_interval", 15) modparam("dispatcher", "ds_probing_threshold", 256) modparam("dispatcher", "ds_inactive_threshold", 1) modparam("dispatcher", "ds_probing_mode", 0) After an upgrade from 5.1 to 5.2.3 (009f62), the round-robin has become extremely "sticky" and tendentious. That is to say, it directs _almost_ all calls to a single gateway -- the first gateway in the table -- though not 100%. There is also a marked tendency to send lots of consecutive calls to the same gateway, even if it's not the first one, though most of the time it is. Has anyone experienced similar upon upgrading to 5.2?

Kamailio DRA - Unable to get diameter_request() function to send
by Nick Jones 10 Aug '19

10 Aug '19

Hi Kamailio users, I'm trying to setup Kamailio as a Diameter Routing Agent, but I just can't seem to get the diameter_request() function to actually send a diameter request, I just get a warning about no JSON Response: *WARNING: ims_diameter_server [avp_helper.c:341]: addAVPsfromJSON(): No JSON Response* Inside my event route I've got one line to send the data to the peer "ims-hss.localdomain": *event_route[diameter:request]{ diameter_request("ims-hss.localdomain", $diameter_application, $diameter_command, $diameter_request); xlog("Forwarded Diameter Request");}* Hard as I try I can't seem to get this request forwarded to this peer and see that next xlog() line. In the config file I've included the cdp_check_peer & cdp_has_app checks to confirm the peer is up, and able to accept the request, (full config in pastebin below) I've defined the peers in the diametercfg.xml config file, and they're all showing as online when I do a "kamcmd cdp.list_peers": * FQDN: ims-hss.localdomain Details: { State: I_Open Disabled: False Last used: 0 Applications: { appid:vendorid: 16777216:10415 appid:vendorid: 16777216:4491 appid:vendorid: 16777216:13019 appid:vendorid: 16777216:0 appid:vendorid: 16777217:10415 appid:vendorid: 16777221:10415 } }* The source of avp_helper.c shows the warning is called if the length of the JSON is <= 0, but as I'm feeding back out what I've received it's not 0, an no recent major changes to the source, so I'm stumped as to why it's catching this. I'm running Kamailio 5.1.2 on Ubuntu 18.04 installed from Repos. Full Kamailio Config: https://pastebin.com/afgqUfWr Diameter CDP Config XML: https://pastebin.com/bVrBG8mG Relevant Syslog: https://pastebin.com/ZY8z2kd4 Kamcmd cdp.list_peers: https://pastebin.com/cKi4JAHC Any ideas as to what am I missing? Thanks in advance! Nick

kamailio as UAC and NAPTR / sendsocket question
by Karsten Horsmann 09 Aug '19

09 Aug '19

Hi List, I try to register to Deutsche Telekom and there product Deutschland Lan siptrunk. Thats works find but i see an intressting behaviour on selecting the right outgoing interface. Kamailio is sending out with tcp the REQUEST via first private ip configured on that server (172.20.120.53). There is no listen directive for that. I forced NAPTR to use tcp or udp and i assume that kamailio got the right dns answers. On the list i read also that i can use force_send_socket to force the outgoing request. Now my idea - hey i use the $rP for the outgoing to select the right outgoing listen directive. $rP - reference to transport protocol of R-URI But to my surprise the logfile told me thats "UDP" - it sends out via TCP (thats okay). Whats an good transport selector variable from kamailio that works? event_route[tm:local-request] { if(!is_method("OPTIONS")) { xlog("L_INFO", "[tm:local-request] request [$rm] from [$fu] to [$ru] [$rP]\n"); } } INFO: <script>: [tm:local-request] request [REGISTER] from [ sip:+49XXXXXXXX@sip-trunk.telekom.de] to [sip:sip-trunk.telekom.de] [UDP] listen=tcp:2xx.xx.xx.xx:5060 listen=udp:2xx.xx.xx.xx:5060 listen=tls:2xx.xx.xx.xx:5061 advertise CFG_EXT_NAME:5061 listen=udp:172.20.120.55:5060 listen=udp:172.20.120.56:5060 listen=udp:172.20.120.57:5060 listen=udp:172.20.120.58:5060 listen=tcp:172.20.120.58:5060 use_dns_cache=on # use internal DNS cache use_dns_failover=on # depends on internal DNS cache dns_srv_loadbalancing=on dns_try_naptr=on dns_retr_time=1 # seconds before retrying a DNS request dns_retr_no=3 # number of DNS retransmissions dns_naptr_ignore_rfc=yes # ignore target NAPTR priority dns_tcp_pref=30 # TCP has second-highest priority dns_udp_pref=10 # use UDP with least priority tcp_connection_lifetime=3605 # set higher than registration expires #dont' restore modparam("uac","restore_mode","none") modparam("uac","restore_dlg",0) ## UAC REGISTER #!ifdef WITH_UAC_REGISTER modparam("uac", "reg_contact_addr", "CFG_PROD_IP") modparam("uac", "reg_timer_interval", 10) modparam("uac", "reg_retry_interval", 10) modparam("uac", "reg_db_url", DBURL) modparam("uac", "restore_mode", "none") modparam("uac", "auth_username_avp", "$avp(AVP_AUTH_USERNAME)") modparam("uac", "auth_password_avp", "$avp(AVP_AUTH_PASSWORD)") modparam("uac", "auth_realm_avp", "$avp(AVP_AUTH_REALM)") #!endif ip a l 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000 link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo valid_lft forever preferred_lft forever inet6 ::1/128 scope host valid_lft forever preferred_lft forever 2: ens192: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000 link/ether 00:50:56:b5:c1:48 brd ff:ff:ff:ff:ff:ff inet 172.20.120.53/24 brd 172.20.120.255 scope global ens192 valid_lft forever preferred_lft forever inet 2xx.xx.xx.xx/29 scope global ens192 valid_lft forever preferred_lft forever inet 172.20.120.56/24 scope global secondary ens192 valid_lft forever preferred_lft forever inet 172.20.120.57/24 scope global secondary ens192 valid_lft forever preferred_lft forever inet 172.20.120.58/24 scope global secondary ens192 valid_lft forever preferred_lft forever inet 172.20.120.55/24 brd 172.20.120.255 scope global secondary ens192 valid_lft forever preferred_lft forever inet6 fe80::250:56ff:feb5:c148/64 scope link valid_lft forever preferred_lft forever default via 172.20.120.253 dev ens192 172.20.120.0/24 dev ens192 proto kernel scope link src 172.20.120.53 2xx.xx.xx.xx/29 dev ens192 proto kernel scope link src 2xx.xx.xx.xx -- Kind Regards Mit freundlichen Grüßen *Karsten Horsmann*

Breaking HTABLE changes from v5.2 to v5.3? Function renamed
by Joel Serrano 08 Aug '19

08 Aug '19

Hi all, Just noticed that when updating from 5.2 to 5.3 I saw some errors in Kam logfile regarding HTABLE module commands failing, the reason is the function 'sht_has_name' has been renamed to 'sht_match_name': https://www.kamailio.org/docs/modules/stable/modules/htable.html#htable.f.s… https://www.kamailio.org/docs/modules/devel/modules/htable.html#htable.f.sh… Not sure if updating this doc is automatic or manual but I think it's definitely worth mentioning: https://www.kamailio.org/wiki/install/upgrade/stable-to-devel Just FYI! Cheers, Joel.

Reload geoip2 database without restart
by Joel Serrano 07 Aug '19

07 Aug '19

Hi guys, Is there a way to instruct the geoip2 module to reload its database without a full restart of kamailio? Maybe some rpc command or something? I haven't found anything in the docs other than the comment about "Database is loaded at startup in cache." which makes me assume that just overwriting the db file wouldn't be enough. Any suggestions? Thanks!! Joel.

Sipt redirection number retrieves old values
by Duarte Rocha 07 Aug '19

07 Aug '19

Greetings, I'm doing VoiceMail detection using $sipt(redirection_number) from SIPT module and i've been having some false positives on the detection. I inspected further and noticed that in some cases $sipt(redirection_number) returns old values from previous messages, which makes me think that it's value is not being correctly refreshed. I'm using this variable on a on_reply_route. As far as i know, $sipt(redirection_number) is read only and can't be refreshed by me in the code. Here is an example : Aug 7 16:51:49 dev_sbc_a_vts01 /usr/local/kamailio-5.2/sbin/kamailio[4746]: ERROR: <script>: VMD2 : Reply Code : 180 ; Sipt Redir = 9610050000 and Call ID = 00158FED-98B7-E911-8B3B-4DA50AE2ED72(a)192.168.24.86 and Cseq = 83 Here is the JSON from the 180 message : https://pastebin.com/zFHKxyav As you can see, there isn't any 9610050000 in the message. What can be causing this issue ? Best Regards, Duarte Rocha

app_ruby - invalid ruby environment attributes or parameters

Hey all, I’m setting up a dev-7 (bd477f) server to test as per the other thread, however I’m getting the following loading my config: ERROR: app_ruby [app_ruby_api.c:465]: sr_kemi_ruby_exec_func_ex(): invalid ruby environment attributes or parameters I’m unsure what this error means - are there expected environment variables or other values that must be set? I didn’t see this issue in dev-4. I thought it might be not able to find the library, but I ran with debug=4 and saw: DEBUG: app_ruby [app_ruby_api.c:193]: ruby_sr_init_child(): test execution without error ERROR: app_ruby [app_ruby_api.c:107]: app_ruby_print_last_exception(): exception: undefined method `>' for false:FalseClass I changed kamailio.cfg to load my generic routing script, and during the onreply_manage it runs: scode = KSR::PV.get("$rs”) This now returns false (which appears to be the second error above, I check if scode is > 599). Has anything changed in the way ruby is loaded in dev-7? I’m using the same ruby/ruby-devel library versions on the same OS. I did this deploy the same with devel-4 a few weeks ago and this didn’t happen. Thanks! Andrew

Hello! We have in configuration : c <sr-users(a)lists.kamailio.org>hildren=3 tcp_children=30 But in 90-95% connections kamailio use one worker (one process) by statitistics netstat -anp. Why not using more other workers (processes) ?

The domain module in 5.1.8 has a memory leak
by Mack Hendricks 06 Aug '19

06 Aug '19

Based on my tests, the memory leak is only exposed when you are using domain attributes, which are stored in the domain_attrs table. I wanted to see if anymore else is running into this issue. *Reproducible use case:* 1) Insert the following into the database insert into domain values (null,"aprilco.com","aprilco.com",now()); insert into domain_attrs values (null,"aprilco.com","pbx_type",0,"0",now()); insert into domain_attrs values (null,"aprilco.com","pbx_id",0,"65",now()); 2) Open a new terminal window and execute: watch "kamcmd core.shmmem" 3) Open up another terminal windows and execute: while true; do kamcmd domain.reload; done *Expected Results:* You will see the shared memory being allocated, but never freed. The more entries you have in the domain_attrs table, the faster it will run out of memory.

Error Registering the user and finding the AVP
by jespinosa 06 Aug '19

06 Aug '19

Hello, My name is Javier, I must first apologize for my little knowledge about the tool and my poor English. I am trying to connect a functional core network LTE with Kamailio and I have used the Polaris Networks Solution that brings an iso with both functionalities. The EPC is correctly configured and working because I can have data connection in my UE, I have also activated all the IMS options in the EPC: I have created the APN with ims identifier, the default carrier QCI assigned is 5 (for SIP signaling), the MME has activated the option to support IMS Voice over the PS session and the HSS and PCRF nodes are configured with the interfaces at the addresses and ports Cx-HSS 127.0.0.1:3868 and Cx-PCRF 10.11.0.35:3868 . There are several parameters that I do not know if it is necessary to activate, for example, in the PCRF the customization of the QCI for the media type, if I must include the OCS and OFCS as nodes, or if in the profile of my APN I must include authentication by PDN AAA. The configuration I use for the IMS is as follows: imsrealm = net1.test imsport = 5060 pcscfgmip = 10.77.0.35 pcscfgmipintf = eth6 pcscfrxip = 10.102.81.111 pcscfrxipintf = eth1 icscfmwip = 127.0.0.21 icscfmwipintf = lo:21 icscfcxip = 127.0.0.20 icscfcxipintf = lo:20 scscfmwip = 127.0.0.23 scscfmwipintf = lo:23 scscfcxip = 127.0.0.22 scscfcxipintf = lo:22 audiobandwidth = 64 videobandwidth = 128 epcrealm = epc.mnc001.mcc001.3gppnetwork.org pcrfhost = pcrf2.morsecore pcrfrxip = 10.11.0.35 pcrfrxport = 3868 hsshost = hss6.morsecore hsscxdxip = 127.0.0.1 hsscxdxport = 3868 Both cores are running on the same machine but I have disabled the option of PCRF Co-located with IMS to be able to edit the pcrf host name since if I enable it it does not reach the peer pcrf.localhost even if the DNS is well configured. My UE is not able to launch the REGISTER by itself when it is going to make a call, so I am using the Google IMSDroid application to be able to launch the SIP requests and check the operation of the IMS. In the application of the UE the configuration is as follows: Identity: Alice Public Identity: sip:<MSISDN>@net1.test (MSISDN=8800000451 configurado previamente en el EPC) Private Identity: sip:<IMSI>@net1.test (IMSI incluyendo MCC y MNC) Password: alice Realm: net1.test (Aunque no sé si debo poner aquí epc.mnc001.mcc001.3gppnetwork.org, pero entonces la petición da error) Network: Proxy-CSCF Host: 10.77.0.35:5060 Transport UDP and NO Proxy-CSCF discovery.

Hi Team, Facing 100% Kamilio CPU issue, here are the details, any pointers/hints would help. Thanks *Scenario:* Random Kamailio CPU shoot, restart fixes it. Happens once or twice in a day.

(no subject)
by jay binks 02 Aug '19

Hey all, looking for a little help. I've been tracking an issue, where a number of SIP Messages ( typically INVITE ) are sent, but Kamailio only see one of them ( the last one). I have verified that the messages are definitely received on the host, as verified with TCPDUMP, but the INVITES never hit the request route block. ( the very first thing is to log the message ) What i've managed to find is, that if I increase worker children, the problem goes away. So I've got a problem, I think I've found the solution, but what I'm struggling with is how to monitor better, so I can be alerted to this in the future. I started by looking at "kamctl stats | grep drop" "core:drop_replies = 14", "core:drop_requests = 10577" however drop_requests seems to include explicit drops in my config. which I do for many reasons, but mainly bad UA or blocked IP's, so this dosnt seem to be what im after. I then went digging in the code ( often the best way to find things ). in receive.c receive_msg() we find some conditions, where we drop the packet ( before calling request route ). right now im looking around line 251 at LM_DBG("dropping the received message\n"); goto error00; Following error00 I see it calls STATS_RX_DROPS which increments stats->received_drops. This is where it gets fun, I cant find where received_drops is ever returned in the stats output. I can see where -SIGUSR1 will trigger this to be dumped, if Kamailio is compiled with that option ( dosnt seem the debian packages are ). however, what im seeking clarification on is, does this get reported in "kamctl stats" Am I just going crazy or is something not quite right here? TLDNR; how do I monitor for Kamailio not having enough worker threads to process incoming messages. FYI I'm seeing about 50Mbps of incoming SIP on this box, and I do perform a decent amount of work on some message types. -- Sincerely Jay

Deleting extra location attribute(location_attrs table) when contact is expired
by Pintu Lohar 31 Jul '19

31 Jul '19

Hi All, Regarding modparam("tm|usrloc", "xavp_contact", "ulattrs") #ref : https://www.kamailio.org/docs/modules/devel/modules/usrloc.html#usrloc.p.xa… . There is some requirement where we need to save some extra location attributes to location_attrs <https://kamailio.org/docs/db-tables/kamailio-db-4.3.x.html#gen-db-location-…> tables $xavp(ulattrs=>deviceIdentify)= "Some str values" and calling save(“location”) , It works well and saved location attribute table but But when contact expired callback is received, udomain_contact_expired_db() does not it delete the extra location attribute from database but deleting the record from location table only ? If not, is there any recommended approach to delete the extra location attributes from the database? or am I missing something to set? Alternate I was thinking could be running timer from Kamailio config and check last_modified time and delete those(based on our UAC expiry setting), is it the right approach. Kamailio Version: 5.2.0. Thanks for your valuable suggestion in advance. Regards Pintu Lohar

Dialog missing when BYE is received from trunk
by Andrew White 28 Jul '19

28 Jul '19

Hi all, I’ve got a call flow where PBX makes a call via Kamailio, which uses the UAC modules to make the call to the trunk. This works great, however I’ve noticed recently that when the BYE comes from the trunk, Kamailio doesn’t recognise the dialog and throws back a 404. Due to this, the PBX never knows the session has ended, and keeps its session open. Here’s the flow from Wireshark: https://i.imgur.com/BxPRrXP.png <https://i.imgur.com/BxPRrXP.png> As you can see, the BYE is received from the trunk, and Kamailio throws a 404. I checked with an rpc dlg.list and at this point the dialog had gone. 30 seconds later, I threw a BYE from the PBX, and because the dialog no longer existed, it got a 481 back. The INVITE to the trunk has the following Record-Route header: Record-Route: <sip:kamailio.public-ip;lr;ftag=mjKtcKaBteQ4Q;vst=AAAAAAYFBQUHAwYHBgRzMwIRGRMcAgJBWBEVCwAbBhtADxBjdGVkLmNvbS5hdQ--;did=624.b2e1> When the first BYE comes in, it still has same did in the Route header. Below I’ve put the output from the dialog list rpc call (before the first BYE) and the relevant log lines. { h_entry: 1062 h_id: 7723 ref: 2 call-id: a9d32620-2b68-1238-048a-0cc47a18705a from_uri: sip:61400123123@pbx.local:5060 to_uri: sip:61400123123@10.0.0.2 state: 4 start_ts: 1564269942 init_ts: 1564269929 end_ts: 0 timeout: 1564313142 lifetime: 43200 dflags: 643 sflags: 0 iflags: 16 caller: { tag: mjKtcKaBteQ4Q contact: sip:pbx.local cseq: 7581172 route_set: socket: udp:10.0.0.2:5060 } callee: { tag: SD5ptp899-1177933201-1564269931305 contact: sip:SDd3mt8-nn9jnirnmqcrvfmvkpm0hmhvgggjgv2io788of70s84u9@trunk.remote:5060;transport=udp cseq: 0 route_set: socket: udp:10.0.0.2:5060 } profiles: { } variables: { { cseq_diff: 1 } } } Jul 28 09:27:30 ip-10-0-0-2 /usr/local/sbin/kamailio[11061]: NOTICE: {2 450917085 BYE a9d32620-2b68-1238-048a-0cc47a18705a} acc [acc.c:279]: acc_log_request(): ACC: transaction answered: timestamp=1564270050;method=BYE;from_tag=SD5ptp899-1177933201-1564269931305;to_tag=mjKtcKaBteQ4Q;call_id=a9d32620-2b68-1238-048a-0cc47a18705a;code=404;reason=Not here;src_user=0400123123;src_domain=trunk.remote;src_ip=trunk.remote;dst_ouser=0400123123;dst_user=0400123123;dst_domain=kamailio.public-ip I’m assuming the 404 is because the Contact header I sent from Kamailio -> Trunk is rewritten, that Contact is Kamailio’s public contact IP. However the dialog has the caller contact within it referencing back to the local PBX, so I would think when Kamailio gets this dialog ID back with a BYE it would relay it back to the original contact, wouldn’t it? Thanks! Andrew

Malformed Route Header
by Duarte Rocha 25 Jul '19

25 Jul '19

Greetings, When a in-dialog request has Route headers, Kamailio will remove the Route Header with it's address when routing the packet. This works perfectly for me in every situation. However, in one of the calls I found a weird behaviour in the removal. So, this is the scenario : Kamailio has two IP's 1.1.1.209 and 1.1.1.205. This is BYE request received in the on 1.1.1.209 The header Route looks like this when it arrives at 1.1.1.209 : Route : <sip:1.1.1.209;r2=on;lr;ftag=5AE0303037363132017D0E65;tbk_i=2_2_Y;tbk_o=128_11_Y;vsf=AAAAABgGBAMDAAUBBQECA3ByAwMcHwIdHQsWHwUMOA--;vst=AAAAABgHDQgBAwsIBQECdnIDAxwfAh0aBB4cAgU5;did=8f5.67c2>,<sip:1.1.1.205;r2=on;lr;ftag=5AE0303037363132017D0E65;tbk_i=2_2_Y;tbk_o=128_11_Y;vsf=AAAAABgGBAMDAAUBBQECA3ByAwMcHwIdHQsWHwUMOA--;vst=AAAAABgHDQgBAwsIBQECdnIDAxwfAh0aBB4cAgU5;did=8f5.67c2> It reaches 1.1.1.205 like this : Route : As you can see, the header is empty and it should contain the 1.1.1.205 URI. Is the header Router malformatted and creating this error ? Best Regards, Duarte Rocha

Re: [SR-Users] [EXT] Re: P-CSCF and I-CSCF ports -RESOLVED
by Woscek, Martin W. 24 Jul '19

24 Jul '19

Hi Ali, Looking through the source code, its not that the port for I-CSCF is hard coded to 5060, its just that it defaults to 5060 if the following is set in the Kamailio.cfg file: dns_try_naptr=no which we had left it disabled. Well I assumed I had all the DNS worked out, I had NAPTR records set for the P,I and S-CSCF. Looking though the pcscf.cfg there is a setting for NETWORKNAME which is set to ims522.ims.org, and is a separate FQDN from the P,I,S-cscf FQDN’s. I always kept the NAPTR rec for ims522 as the same port of the P-CSCF (pcscf522) in DNS. Two things I needed to fix: 1. Enable the DNS NAPTR lookups: dns_try_naptr=yes 2. Modify the NAPR for ims522 to be that of 4060 Thanks to you and Amar for the pointing to DNS. _Martin From: sr-users <sr-users-bounces(a)lists.kamailio.org> On Behalf Of Ali Shirvani Sent: Tuesday, July 23, 2019 1:40 PM To: Kamailio (SER) - Users Mailing List <sr-users(a)lists.kamailio.org> Subject: [EXT] Re: [SR-Users] P-CSCF and I-CSCF ports Hi Martin, As Amar pointed out it may some DNS configuration.

kamailio 4.4.4 fills IPv6 contact address when sending packet over IPv4
by Pali Rohár 24 Jul '19

24 Jul '19

Hi! I detected strange problem that sip.linphone.org refuse to accept presence information re-transmitted by kamailio 4.4.4 server. I debug this problem with tcpdump and I found out that problem is in kamailio which fills IPv6 address into UDP datagram and that datagram is sent via IPv4 socket to IPv4 address, to sip.linphone.org server. And sip.linphone.org server does not have IPv6 connectivity, so correctly return over IPv4 to sender just "400 Bad Contact Header" error. On my server is running kamailio 4.4.4 from Debian Stretch and I can 100% reproduce this problem against public sip.linphone.org server. My server has both IPv4 and IPv6 connectivity and kamailio is listening for both IPv4 and IPv6 connections. So why is kamailio sending IPv6 address over IPv4 and therefore makes it impossible to communicate with non-IPv6 enabled servers? Looks like a problem with choosing default/correct socket for Contact header. And how to fix this problem? Can you help me? I would like to have working interconnection with linphone servers. Just to note I'm seeing this problem only for presence information packets. Other requests, like INVITE or MESSAGE seems to work. Below is relevant tcpdump output. Some parts were replaced by {VAR}. PS: I'm not subscribed to list, so please CC my address when sending reply.

How to hook to Register And Unregister event in Kamailio
by Anuran Barman 24 Jul '19

24 Jul '19

Hi, I am integrating Kamailio into my application. I want to hook to the successful REGISTER and unregister event into Kamailio into my application. For now, I am able to hook into INVITE event and can hit my server to send a email to the callee user that user X is calling you. The way I am doing is by this if (is_method("INVITE")) { xlog("LOG_LOCAL3","L_INFO","invite came ($fU) ($tU)"); $var(res) = http_connect("sipnodejsserver", "/","text/plain","src_user:$fU,dst_user:$tU" ,"$avp(route)"); xlog("LOG_LOCAL3","L_INFO","request sent $avp(route) $var(res)"); setflag(FLT_ACC); # do accounting } I need to show into my application that their SIP phone is online or not. How can I hook into this?

Debugging kamailio module
by Ali Shirvani 23 Jul '19

Hi all, I want to trace function calls in a kamailio module, e.g. ims_isc module. I installed kamailio-dbg package and started the kamailio with gdb: `gdb kamailio` I also set break point on target function, but it seems gdb doesn't stop on that break point. How should I start gdb and set break points? it seems gdb couldn't handle kamailio child processes that forked in start. Regards, Ali

Two GWs with the same IP
by Duarte Rocha 22 Jul '19

22 Jul '19

Greetings, I'm building some testing procedures for my Kamailio proxy. In order to do that i have a SipTester (Acting as Calling Number) from where i want to originate calls to Kamailio. After Kamailio processes the call, i want it to route it to SipTester again so it can act as Called Number. This should work with only one SipTester in one machine, so i created two SipTester GW's on Kamailio, belonging to different users and GW groups. Also, the two GWs use different Kamailio addresses to communicate with the proxy. However, in this combination, when routing i get this error " ERROR: dialog [dlg_handlers.c:666]: pre_match_parse(): bad request or missing CALLID/TO hdr :-/". If i change the destination or the origin of the INVITE the calls work without a problem. Does this happen because both GW's have the same address? Best Regards

Reading presence state
by Gertjan Wolzak 19 Jul '19

19 Jul '19

Hello Kamailions, I have been able to get the presence configured, subscribers see the status of their subscriptions, this is working fine, for internal, incoming external and external calls. This was solved by enabling use_pubruri_avps in the pua_dialoginfo module. Now I want to be able to route calls based on the presence state. Using the presentity table could be used by doing a query based on the userpart of the ruri, which works fine when the call is still active, but it can take a while for the record to be removed from the presentity table, as that is dependend on the expires value. So when a query is made after a call is finished, a record would still be present in the presentity table till clean_period timer has hit again and the expires value is expired. So I should get the status from memory, but I have not been able to find the information on how to do that. Can someone enlighten me on where to find that information? Rgds, Gertjan

Kamailio IMS to IP PBX - how?
by David Dean 16 Jul '19

16 Jul '19

I'm trying to connect a VoLTE smartphone to an IP PBX using Kamailio IMS. I've managed to get the smartphone to connect to Kamailio IMS and make calls with our devices registered with Kamailio. The problem is that I need the smartphones to register with the IP PBX which is a VigorBX 2000n. This is so they can use an internal extension number and make calls to other local extensions with hard wired desk phones. Should I be using Kamailio IMS to "proxy" the smartphone SIP connection to the VigorBX PBX? Or would it be better to connect the smartphone directly to the VigorBX using SIP? If so, how? I've read absolutely every how-to document I could lay my hands on but none of them describe integrating IMS with a PBX. Thanks for any help / advice you can offer. Dave

How to get total number of dialogs in profile with value
by Nathan Angelacos 15 Jul '19

15 Jul '19

In kamailio < 5.1.x it used to be possible to get total number of items in a dialog_with_profile by skipping the "value" paramter, such as: modparam ( "dialog", "profiles_with_value", "outbound" ) . . . get_profile_size ( "outbound", "$var(myvar)" ); However, 5.1.x and 5.2.x report: ERROR: dialog [dialog.c:912]: w_get_profile_size_helper(): invalid value parameter The documentation ( https://kamailio.org/docs/modules/5.2.x/modules/dialog.html#dialog.f.get_pr… ) Indicates the "value" paramter is still optional. I'm sure I must be missing something obvious... Any ideas? Thanks!

UDP fragmentation issues
by Gerry | x164 15 Jul '19

15 Jul '19

Hi, I have setup Kamailio on Centos 7 as a proxy in front of Asterisk in the same datacenter, using the dispatcher module. I have noted that large INVITEs sent by Kamailio do not arrive at the Asterisk box. It seems the network is dropping fragmented UDP traffic. This does not happen however when I contact the Asterisk box directly from outside the datacenter. Then large INVITES are arriving are Asterisk. So the problem is either in Kamailio or in the datacenter. I have analysed the problem with ngrep and tcpdump/wireshark. In normal mode (udp4_raw=no setting) Kamailio is producing UDP packets above 1500 bytes and leaves all fragmentation to the operating system. Enabling raw udp in Kamailio and lowering the MTU in the server didnt help. I even disabled offloading of UDP fragmentation to the NIC to get to the bottom of this. However nothing helps. Only forcing TCP in the dispatcher works when having large INVITES going to Asterisk. In any case, it appears that there is no guarantee that fragmented UDP arrives at all. As far as I am aware, the recommendation is to use TCP if messages are bigger than 1400 bytes. If so, how can I force Kamailio to send messages over 1400 bytes only in TCP mode? Or is there some other way how to deal with this? Thanks for any hints. Gerry

Kamailio Asterisk integration with docker DNS Problem
by Amir 15 Jul '19

15 Jul '19

Hi I have created a kamailio container with docker and two asterisk container And this is my dispatcher list: *1 sip:asterisk:50601 sip:asterisk2:5060* and this is my both asterisk SIP.conf *[Kamailio]host=kamailioport=5060insecure=invitetype=friendcontext=from-internal* The problem is that I use User-defined networks which has its own DNS when a container starts a dns record would be set If I start a kamailio first then start two asterisks the asterisk works fine because the name "kamailio" has been set in docker dns but I should restart the kamailio because at startup It could not resolve astersik dns records after the everything works fine but if the any of the asterisk instances crash/stop kamailio can not detect that because a dns record would not be available: *17(22) ERROR: <core> [core/resolve.c:1684]: sip_hostport2su(): could not resolve hostname: "asterisk2"17(22) ERROR: tm [ut.h:309]: uri2dst2(): failed to resolve "asterisk2"17(22) ERROR: tm [uac.c:452]: t_uac_prepare(): no socket found17(22) ERROR: dispatcher [dispatch.c:3110]: ds_ping_set(): unable to ping [sip:asterisk2:5060]* It is kind of loop , I think maybe I can fix asterisk problem with asterisk realtime and set the sip.conf in database. anyone has any suggestion for this problem?

Wrong $rm value

Hello list, I use kamailio 5.2.3 from repo's on stretch in docker. I use python KEMI + async and encountered weird behaviour: after t_continue $rm shows OPTIONS instead of REGISTER/INVITE. I wonder if that's correct behaviour, because for me it looks like a bug. Repeating is easy - just check $rm after t_continue. ________________________________ Regards, Alexandru Covalschi VoIP Engineer and System Administrator tel: +37367367850

Now, we would like to validate inbound calls coming from this registered provider, sending them to a specific dispatcher group. I tried reading the uac module docs, found *uac_reg_lookup* function, but i'm not sure if that's we need. Could someone please help me to understand if UAC has a function to do that, or if we need to make some? Thanks!!

Long distance rtpengine communication

Hi all, We have kamailio servers which communicate with the geographically distributed rtpengine servers. Sometimes udp packets are lost or delayed between kamailio and rtpengine.

Are there any suggestions to overcome this problem? Thanks, Koray

SIP URI Evaluation and Forwarding
by Ronald Hartmann 12 Jul '19

12 Jul '19

Good Day List, I am very new to Kamailio and trying to understand at 10,000 feet how it may be able to be used. I was wondering if the following Scenario would be possible and if so what modules would accomplish this aspect. (Any URLs for further reading would be appreciated) Scenario: Given 1) SoftPhones will register as follows sip uri, user(a)subdomain.myvoipserver.com 2) The following users are authorized to connect (this would be stored in a config file etc): 1001,1003,1007 are valid users for apples.myvoipserver.com 1001,2213,5817 are valid users for oranges.myvoipserver.com Is it possible for Kamailio to perform the following evaluation and then take the appropriate steps: If [domain is apples.myvoipserver.com AND user portion is 1001] then Forward/Proxy the SIP/RTP packets to Asterisk server responsible for registration and audio for the domain apples.myvoipserver.com Else if [domain is oranges.myvoipserver.com AND user portion is 2213] then Forward/Proxy the SIP/RTP packets to Asterisk server responsible for registration and audio for the domain oranges.myvoipserver.com Else Silently Drop packets etc. given the above evaluation rules, a user who tries to register as 1001(a)apples.myvoipserver.com would be granted access and their SIP Packets and subsequent RTP would be forwarded to the asterisk server at apples.myvoipserver.com, where said server would take care of the Registration, and any subsequent calls, subscriptions, Options etc. 1004@ apples.myvoipserver.com Would not match the authorized list for apples.myvoipserver.com (1001,1003,1007), therefore this registration attempt would be silently dropped 2213(a)apples.myvoipserver.com would be granted access and their SIP Packets and subsequent RTP would be forwarded to the asterisk server at oranges.myvoipserver.com, where said server would take care of the Registration, and any subsequent calls, subscriptions, Options etc. Thanks for any information to assist me in understanding how this would work. ~ron

Re: [SR-Users] kamailio warning
by Henning Westerholt 10 Jul '19

10 Jul '19

Hello Ali, (please keep the sr-users list in CC, that other people can also participate) Remove the “-D” from your Kamailio command line – then the warning will disappear. This is also necessary because you want to have Kamailio listen on several addresses. If you want to test it more in a production like setting, you should also remove the “-E” from the command line. You will find the logging in your system log then.

Hello, Could someone help me to set a variable as a string in Kamailio? At the moment i'm using the following statement: *$var(account)=$(au{s.substr,0,8}); * *xlogl("L_INFO", "[1234] Account: $var(* *account* *)\n");* which is working fine, but i need to change it into: *$var(account)=$(au{s.select,0,-}{s.toupper})-$(au{s.select,1,-});* By doing this I'm getting the error: *[core/rvalue.c:1007]: rval_get_int(): automatic string to int conversion for "AT" failed[core/rvalue.c:1912]: rval_expr_eval_int(): rval expression conversion to int failed (729,30-729,59)* I tried also: *$var(account)="" + "$(au{s.select,0,-}{s.toupper})-$(au{s.select,1,-})";* But, then I'm getting: *Account = $(au{s.select,0,-}{s.toupper})-$(au{s.select,1,-})* instead of the value. What is the correct way to set it? Thank you.

by Albert Petit 09 Jul '19

09 Jul '19

hi i would need to replicate behaviour of refresh watchers command at mi_datagram module in an ipv6 system. but in such system i am not able to bind this module in an iov6 address desoite its doc claims is possible https://kamailio.org/docs/modules/4.4.x/modules/presence.html#idp21723212 hence not sure i will be able to use mi_datagram using ipv6 address unless some user tells me he/shr could do succesfully as module is quite old question is: h¥w could i force kamailio to notify watchers of a subscriber in some other way from an external application? any hints? thanks
