Re: [SR-Users] LCR routing, and finaly route to media gateway if not found
by Loic Chabert 23 Sep '16

23 Sep '16

In fact, kamailio is out from lcr at this point, no more gateway to try (all gateways are down). I just want to send call to a static server for playing sound. To be more specific, if no gateways are not set on database, a sound must be played. Should i change $du and $ru to make it work ?

Kamailio ims nat issue: PRACK/ACK ruri changing in p-cscf
by Owais 23 Sep '16

23 Sep '16

Hi all, My scenario is as follows: I have All the CSCFs on the same IP using different ports. P-CSCF advertises a public IP. Rest of the nodes including I-CSCF and S-CSCF listen local only. Behavior: When an ACK or PRACK goes from P-CSCF to S-CSCF, the RURI changes such that alias parameter is removed. Hence, P-CSCF ends up sending PRACK and ACK on private IP of UE. Here's what the config looks like: #!define WITH_NAT Any hints? -- View this message in context: http://sip-router.1086192.n5.nabble.com/Kamailio-ims-nat-issue-PRACK-ACK-ru… Sent from the Users mailing list archive at Nabble.com.

Problem reseting TMX statistics
by Átila de Moura Tavano Moretto 23 Sep '16

23 Sep '16

I'm currently using version 4.4.2 and am having trouble trying to reset the statistics in the TMX module. According to its documentation, all statistics except "inuse_transactions" can be reset. Checking the tmx_mod.c files for the statistics definition, I saw that the STAT_NO_RESET flag wasn't used for any statistic listed there (which seems odd because I think it should have been set for the inuse_transactions statistic): static stat_export_t mod_stats[] = { {"UAS_transactions", STAT_IS_FUNC, (stat_var**)tmx_stats_uas_trans }, {"UAC_transactions", STAT_IS_FUNC, (stat_var**)tmx_stats_uac_trans }, {"2xx_transactions", STAT_IS_FUNC, (stat_var**)tmx_stats_trans_2xx }, {"3xx_transactions", STAT_IS_FUNC, (stat_var**)tmx_stats_trans_3xx }, {"4xx_transactions", STAT_IS_FUNC, (stat_var**)tmx_stats_trans_4xx }, {"5xx_transactions", STAT_IS_FUNC, (stat_var**)tmx_stats_trans_5xx }, {"6xx_transactions", STAT_IS_FUNC, (stat_var**)tmx_stats_trans_6xx }, {"inuse_transactions", STAT_IS_FUNC, (stat_var**)tmx_stats_trans_inuse }, {"active_transactions", STAT_IS_FUNC, (stat_var**)tmx_stats_trans_active}, {"rpl_received", STAT_IS_FUNC, (stat_var**)tmx_stats_rcv_rpls }, {"rpl_absorbed", STAT_IS_FUNC, (stat_var**)tmx_stats_abs_rpls }, {"rpl_generated", STAT_IS_FUNC, (stat_var**)tmx_stats_rld_loc_rpls}, {"rpl_relayed", STAT_IS_FUNC, (stat_var**)tmx_stats_rld_rcv_rpls}, {"rpl_sent", STAT_IS_FUNC, (stat_var**)tmx_stats_rld_tot_rpls}, {0, 0, 0} }; All seems ok, but when I try to reset the stats, the command simply doesn't work. The values remain unaltered. The clear command doesn't work either, it just returns the current values. Can anyone help me trying to debug this problem, I'm very new to Kamailio and its code, and don't have a good understanding of how it the statistics gathering/reset works. Thanks. Atila Moretto

Location Table In db_mode 3
by Gholamreza Sabery 23 Sep '16

23 Sep '16

I have multiple Kamailio servers in an Active/Active scenario (the database is a MySQL server) using db_mode 3. But when the number of clients goes up writes on the location table become too much and it causes database problems. I even put my location table on a separate SSD disk on the server to separate it's IO but still at times I have problems. How can I move location table into memory? Is this a good solution? What other options do I have?

Dimension number of child
by Igor Potjevlesch 23 Sep '16

23 Sep '16

Hello, I'm wondering if there's a best practise to dimension the number of child to setup? I see, very often, Kamailio that stops to reply to SIP traffic for couple a seconds. This cause some calls drop if RE-INVITE are not processed for example. So, I'm wondering if the issue is not due to a lack of child for processing the SIP traffic. Thank you for your inputs. Regards, Igor.

failed to find command http_async_query - Even though module loaded
by Jonathan Hunter 23 Sep '16

23 Sep '16

Hi guys, I am using the http_async_client module to POST some requests to a Web Interface, and on server 1 it all works well. I have done a fresh install from github, version 4.4 on Centos 6.8 on server 2, and kamailio wont start. Its the same configuration file, however it states; failed to find command http_async_query (params 3) However the module is loaded, and when installing no errors were written when creating the module, and in terms of its links they are below and look ok to me.

Selective rport behaviour
by Alex Balashov 23 Sep '16

23 Sep '16

Hi, In some scenarios, it happens that a request is received with the following characteristics: IP xxx.xxx.xxx.xxx:14000 -> server:5060 Via: SIP/2.0/xxx.xxx.xxx.xxx:5060;branch=9hG4bKblah;rport Normally, we just force_rport() on all incoming requests so that we reply to the real source port of the request, since most endpoints on this installation are NAT'd. However, occasionally we run into a scenario where an ALG or misconfigured client incorrectly inserts an rport attribute into its topmost Via, and really expects to receive a response at the address/port indicated in the Via (i.e. 5060). Does Kamailio offer a means of dealing with these on a selective basis? Would refraining from calling force_rport() be enough? Or would it be necessary to set reply_to_via=1 as well, thus breaking symmetrical behaviour for the vast majority of the NAT'd endpoints? In other words, I'm not 100% clear on the following: 1) What impact does force_rport() have if an 'rport' attribute is sent by the client? In this case, there should be nothing to "force"; I assume that if the 'rport' attribute is placed by the client, then the proxy will return replies to the source port of the request even if force_rport() is not called, because that's the RFC 3581-compatible thing to do. Right? 2) Does reply_to_via=1 override the behaviour hypothesised in #1? 3) Does reply_to_via=1 override force_rport()?

Killing dialog using kamcmd
by Laura 22 Sep '16

22 Sep '16

Dear list, i have developed a tool that automatically stop the call after some trigger i use.. For do that i use the kamcmd dlg.end_dlg command. It work perfectly but i have noticed a problem over the kamailio acc table. When i kill a specific call using this command.. the acc table don't write the BYE record for the dialog.. Is that correct ? how can i fix.. I'm using ngrep for verify the SIP dialog and i see the BYE command correctly on the A and B leg of the call.. Thanks for any idea. Laura

ndb_mongodb -Sending Query to Mongo
by Jonathan Hunter 22 Sep '16

22 Sep '16

Hi Guys, I am using the ndb_mongodb module, and Im just trying to return values from the dispatcher table, in particular the setid of a particular entry depending on its attrs value. If I query using mongodb shell command it works fine, here I enter test.com and it returns only the setid value, or 2; db.dispatcher.find( { attrs: "test.com" }, { setid: 1, _id: 0 } ){ "setid" : 2 } However I have been having issues getting this to work using mongodb_find_one, as I would of thought the following route return the same; if(mongodb_find_one("ml-mongodb", "kamailiosbc", "dispatcher", "{ \"attrs\" : \"test.com\" },{ \"setid\": \"1\", \"_id\": \"0\" }", "mgr1")) However it returns all the entries relating to that attrs columm from dispatcher table, instead of just setid. Is it possible to do this? I am stuggling to find the json format to acheive the same thing. Also in terms of the mgr1 response, I see its contained within the $mongodb(key), can I drill down to get specific fields from it or would I need to use transformations or jansson to do this? Many thanks Jon

STUN server - stun_allow_stun
by Hermann Norpois 22 Sep '16

22 Sep '16

Hello, I have some STUN questions. My plan is to build a P2P connection with ICE (psua2 or libnice). 1) According to the cookbook ( http://www.kamailio.org/wiki/cookbooks/4.0.x/core) one can activate an internal STUN server: stun_allow_stun = 0 | 1 (off | on); default 1 This is followed by: "Note: STUN support is only available if sip-router/Kamailio was compiled with STUN support (“make STUN=1 cfg”)" I did an installation with sudo apt-get ... Is STUN support availbable? How do I check for STUN support? 2) I ICE it seems to be usual that the body of the SIP request contains an SDP message that includes the IP addresses and ports to be used. So the results of the STUN request (and TURN request possibily) are already included. How does the kamailio STUN server work? Is it an independent STUN server (caller asks the kamailio STUN server - gets an answer - encodes an SDP with the external IP adress an port information - starts the SIP INVITE) ? Or does Kamailio change SDP lines after contacting the internal STUN server? 3) Is the kanailio STUN server prefered to other STUN servers, for instance stun.stunprotocol.org? Thanks Hermann

Problem using ds_is_from_list in failure_route
by Joel Serrano | VOZELIA 21 Sep '16

21 Sep '16

Hi all, I'm facing a strange problem using ds_is_from_list in the failure_route block. I have 4 servers in a dispatcher group 8201. Scenario: A call comes in, gets routed to a backend server from 8201 dispatcher group, the backend replies with a 480. Then we have: onreply_route[MANAGE_REPLY] { [...] if (ds_is_from_list("8201")) && t_check_status("480") { <<<<<< This gets executed, because the node is in 8201 and the reply was a 480 if (is_present_hf("X-UserID")) { $var(UserId) = $hdr(X-UserID); } } [...] } So far so good, next is: failure_route[MANAGE_FAILURE] { [...] if (ds_is_from_list("8201")) && (t_check_status("480")) { <<<<<< This does NOT get executed. append_hf("X-UserID: $var(UserId)\r\n"); if (!ds_select_domain("8205","4")) { xlog("L_ERR", "[$ci] - No additional gateways\n"); t_reply("502","Bad Gateway"); exit; } t_set_fr(0,2000); route(RELAY); } [...] } To find the problem, I added some logging in the failure_route before entering the IF statement: if (ds_is_from_list("8201")) xlog("L_NOTICE", "DS is in group 8201"); <<<<< No log, so did NOT match. if (t_check_status("480")) xlog("L_NOTICE", "Status is 480"); <<<<< Yes log, so DID match. According to the docs, ds_is_from_list can be used in any route block, so I think I am definitely doing something wrong... or maybe it's a bug?? The idea is to achieve this: Call comes in from softphone into proxy, proxy sends it to backend, if backend replies with a 480, send it to another dispatcher set (8205). If the 480 comes from somewhere that is not the backend (8201), then do nothing. Any suggestions? Thanks in advanced. Best regards, Joel.

parameter not found in module dialog
by Michael Jepson 21 Sep '16

21 Sep '16

Hi all, I am trying to limit concurrent calls, using dialog, or rather, I want to try it. I have now only added loadmodule "dialog.so" and a series of modparam commands to my config file and already I am running into problems: ERROR: <core> [modparam.c:139]: set_mod_param_regex(): parameter <toroute_column> of type <1> not found in module <dialog> It fails on the last modparam line, but if I remove it (by commenting it), it fails on whatever the latest modparam line is after that. I have tried removing multiple calls, but every time it fails on whatever is the last line. I have the required modules already loaded (tm.so, rr.so and pv.so), so that's not it I guess. Any idea what might be causing this issue? Also, I noticed (when calling locate dialog.so on the Linux machine) that there is also an ims_dialog.so, if I replace dialog with ims_dialog, I run into the exact same issues. Any help is greatly appreciated! Best regards, Michael Jepson CM Telecom

OOM Errors
by Phil Lavin 20 Sep '16

20 Sep '16

Hi all, Kamailio stopped performing some functions earlier today, citing OOM errors. An excerpt from the log is below. SHM usage, at the time, looked fine. Also see below for that output. A restart of Kamailio resolved the issue.

Presence: Empty reginfo NOTIFY bodies
by Stefan Kohlhauser 19 Sep '16

19 Sep '16

Hey everyone! Problem: At startup the presence module for reginfos can get into a state where it is not adding bodies to reginfo NOTIFYs. Setup: We are using the pua_reginfo to let the Kamailio (4.2.6) PUBLISH the current registration state to itself. The body is correctly added to the presentity-table in the Postgres. Analysis: However, we have identified two cases where after startup the Kamailio can reach a state where he won't add bodies to the NOTIFYs. And this does not fix itself over time. We are pretty confident that the problem lies in an inconsistency between the presentity table in the DB and the hashtable of the presence module. Case 1: The entry for a URI in the DB is expired. On startup of the Kamailio the hashtable remains empty for that URI. Maybe due to another bug the pua_reginfo occasionally sends PUBLISHes with an expired "SIP-If-Match"-header. In module/presence/presentity.c::update_presentity() the DB is updated. However, the hashtable is only updated if it is a new request (i.e. no "SIP-If-Match"-header and thus new_t not set). The hash table is not filled on startup, not on the first PUBLISH as it contains a (wrong) "SIP-If-Match"-header, and not on any subsequent PUBLISH as they contain correct "SIP-If-Match"-headers. Case 2: The presentity table contains at least one expired and one non-expired reginfo entry for a URI. The Kamailio seems to send a NOTIFY with a body within about a minute (probably the default clean period of 100 secs?). But after that short interval only NOTIFYs with empty bodies are sent. To us it looks like the cleanup function (module/presence/publish.c::msg_presentity_clean()) is cleaning up the expired DB entries correctly. But despite one still valid entry in the DB the entry in the hash table gets removed as well. And it wont get filled again (see case 1). This only seems to apply to the "reg" event, the "presence" event does not seem to be affected. We are aware aware of the publ_cach parameter, but we don't know if this has any performance impact on our system. If needed we can try to provide more insight on this problem. Some help on this or a fix would be much appreciated! BR, Stefan

Kamailio P-CSCF error on INVITE
by Owais 19 Sep '16

19 Sep '16

Hi guys, Kamailio P-CSCF is unable to return true for: pcscf_is_registered("location") on INVITE and responds to the INVITE with: 403 Forbidden - You must register first with a S-CSCF Registration completes fine and I can see database with valid location entries though... Any ideas? Regards, Owais -- View this message in context: http://sip-router.1086192.n5.nabble.com/Kamailio-P-CSCF-error-on-INVITE-tp1… Sent from the Users mailing list archive at Nabble.com.

how to access reply headers
by mjbemail2000-seti＠yahoo.co.uk 19 Sep '16

19 Sep '16

Hi, I have a registered handset which replies to an INVITE message from Kamailio with a "302 Moved Temporarily" message. The reason for this is because the user has set their handset to forward the call to another telephone number. In a wireshark trace I can see the forwarded telephone number in the Contact header of the SIP message but I can't find a way to access this header via any variables. In the config file I have tried this: # Manage incoming repliesonreply_route[MANAGE_REPLY] { ... if(t_check_status("3[0-9][0-9]")) { xlog("L_INFO", "test1: $hdr(Contact)"); xlog("L_INFO", "test2: $ct"); } ... } , but in both cases the value returned is the Contact header of the original INVITE message and not the Contact shown in the "302 Moved Temporarily" reply message. How do I access the Contact header in the reply message? Regards, Mark.

Hi, I've installed Kamailio on CentOS using yum but it's not installed the geoip2 module, amongst others. I'm I correct in saying that to install this module I'd need to install Kamailio from the source code? Regards, Mark.

Extract param from RPID header
by Grant Bagdasarian 19 Sep '16

Hello, I'm trying to extract the privacy param from the RPID header, but without success. Could someone point me in the right direction? Remote-Party-ID: "Cullen Jennings" <sip:+3123456789@1.1.1.1>;party=calling;privacy=off;screen=no. I've tried the following ways: 1) TEXTOPSX: $var(rpid_privacy_value) = @hf_value.remote_party_id.privacy; 2) Param Transformations: a. $(hdr(Remote-Party-ID){param.value,privacy}) b. $(re{param.value,privacy}) c. 4re{param.value,privacy} I can't seem to extract the value of privacy from the RPID header.

Self challenged packets
by Torsten Hantzsche 19 Sep '16

19 Sep '16

Hi, while playing with the script from http://kb.asipto.com/kamailio:presence:k43-blf and "kamailio 4.4.3 (x86_64/freebsd) 5a2195" I could not see any NOTIFY packet going out to the subscribed watcher. "tcpdump -i lo0" shows self injected PUBLISH packets challenged with "407 Proxy Authentication Required" and there they got stuck. The PUBLISH packets are sent on lo0 from my network address to the same network address (here 10.0.0.106 to 10.0.0.106). The proxy challenge is also sent from 10.0.0.106 to 10.0.0.106. An xlog entry with the variable "$Ri" in route REQUEST shows 10.0.0.106 too. Since these packets are only seen on lo0, should "$Ri" not show 127.0.0.1? After disabling the WITH_AUTH variable, the watcher is getting its NOTIFY's. Now I wonder under which circumstances this script is supposed to function correctly without changes in the AUTH route? By the way, I had the same problem with the provided script of the msilo module (http://kamailio.org/docs/modules/4.4.x/modules/msilo.html#idp42867388) which too only works if there is no "auth_challenge" in the way. Could somebody with more insight in Kamailio internals give some hints on this, please? How can it get solved in an elegant way? Thanks, Torsten

Replacing Asterisk with Kamailio
by Valter Nogueira 17 Sep '16

17 Sep '16

I use Asterisk for SIP and Media Proxy. Despite the fact that Asterisk is not a SIP Proxy at all. Customer registers in a SIP account, sends the invite and thru de context Asterisk dials out thru a SIP Trunk. Asterisk does the media proxy, since customer can't route directly to the SIP Trunk (altough it has a valida address, it don't have a public route allowed to it). I need limit customer concurrent calls, mangle some dial-in/dial-out numbers, keep track of ongoing call, control SIP dialog, retransmit correct hang-up causes and do media proxy (no transconding at all) After reading about Kamailio and Opensips, and due to the Kamailio Admin Book, I decided to go with Kamailio. Well, I understand that I have to use some kamailio modules, like auth, dialplan, rtpproxy and db_mysql. What make me stuck is how does everything fit together in kamailio.cfg and how do I get ongoing calls and CDR's? Can anyone point me a direction? Thanks

Commercial SBC or Kamailio
by Linux Vince 16 Sep '16

16 Sep '16

We are trying to setup VOIP infrastructure, mainly wholesale and retail. What is best option if money is not the problem? Developing our own infrastructure using Kamailio and other open source packages to act as SBC and switch or buy a commercial solution like GenBand/Sonus/Sansay. We are looking for high performance with scalability to handle thousands of call setups per second over the period of few years. I have no idea on how/if can kamailio outperform commercial solutions or not. Advantage of using kamailio is flexibility and possibility of customization as per requirement, I am new to this list so please advise if this is not a valid question to be asked here.

Kamailio fails to start when MySQL down
by Daniel Pocock 16 Sep '16

16 Sep '16

I recently set up a Kamailio instance using the default configuration for HOMER with MySQL[1] The database was not running and Kamailio refused to start. Would it be better for Kamailio to start anyway and go into a loop trying to connect to the database, just as if auto_reconnect was set? This is useful for people who start Kamailio from their init script and can't be sure if their database host is up before their Kamailio host boots 1. https://github.com/sipcapture/homer-api/blob/master/examples/sipcapture/sip…

Integration with Broadsoft and Config Question
by Daryn Johnson 16 Sep '16

16 Sep '16

I’m looking to briefly check the sanity of my configuration. I have been working w/Kamailio the last few months, and have read the SIP router ebook. Thank you for your efforts and the documentation. It has been a GREAT HELP! We are attempting to replace an Acme Packet SBC, and our setup is as follows: |ACCESSUSERS| ⇔ |KAMAILIO/SEMS| ⇔ |BROADSOFT| ⇔ |GENBAND| ⇔ |PSTN| Kamailio & SEMS are (currently) on the same box, and communicate using localhost via different ports. They also listen on the same private (core) IPs, using different ports. Since Broadsoft doesn’t support the PATH header, I manipulate the contact header w/the SEMS privateIP & port in the contact header. This causes it to be stored in the Broadsoft Registration string, and calls from PSTN route directly to SEMs to start calls etc… Registraton code looks like this: route[REGISTRATION] { remove_hf("Route"); add_path_received(); $avp(contact) = $ct; xlog("L_INFO", "found contact header $avp(contact)"); setflag(FLAG_REGISTRATION); if (nat_uac_test("20")){ xlog("L_INFO", "[REGISTRATION_ATTEMPT] [FROM_NAT] R=$ru ID=$ci UA='$ua'\n"); force_rport(); remove_hf("Contact"); append_hf("Contact: <sip:$fU" + "@" + "!SEMSPRIVATEIP!:5060;" + "alias=$si~$sp~1>\n"); setflag(FLT_NATS); } else { xlog("L_INFO", "[REGISTRATION_ATTEMPT] [PUBLIC_IP] \r\n[REGISTRATION_INFO] R=$ru UA='$ua'\r\n"); remove_hf("Contact"); append_hf("Contact: <sip:$fU@" + "!SEMSPRIVATEIP!:5060;" + "alias=$si~$sp~1>\n"); } $du = "sip:R_IP:REGISTRAR_PORT"; t_on_reply("REG"); route(RELAY); exit; } Then in the relay route, I force the registration out of the private interface & port of Kamailio if (isflagset(FLAG_REGISTRATION)){ $fs = "LISTEN_UDP_PRIVATE"; } Finally, if a registration is successful from BROADSOFT, I store it in the location table, to allow me to screen calls from access to ensure they are ‘registered’ onreply_route[REG]{ if(status=="200") { xlog("L_INFO", "REGISTRATION BE GOOD FOR $fu"); save("location", "0x04"); } } Calls from ACCESS, I check USRLOC for screening, then pass the call to SEMS via the localhost:port. From there, sems enacts the B2BUA/SBC module and routes the call to BROADSOFT, and along to our GENBAND Gateway… I could never get calls to work properly without SEMS, just using RTP PROXY/ENGINE, possibly because the RTP for the GENBAND & KAMAILIO/SEMS are on different private subnets. Our setup is fairly legacy ‘heavy’ and many things can’t be changed. Calls from PSTN route to GENBAND, then BROADSOFT, then SEMS, then KAMAILIO. Since I have manipulated the contact header, BROADSOFT maintains that in the INVITE and I can use the ‘handle_ruri_alias’ to route the call properly. SEMS sets the PUBLIC IP of the KAMAILIO/SEMS box in the SDP, and facilitates rtp relaying. if (isflagset(FLAG_TOUSER)){ xlogl("L_INFO", "TOUSERFLAGSET"); if(is_method("INVITE|BYE")){ handle_ruri_alias(); } /*if(has_body("application/sdp") && nat_uac_test("8")) { fix_nated_sdp("10"); xlog("L_INFO", "SDP CONTAINS NAT"); }*/ $fs = "LISTEN_UDP_PUBLIC"; } I’ve gone headlong into this setup, and it works! But, I wanted to get a ‘Sanity Check’ to determine if there is a better way to do this. We are at the point where I’m doing load testing and attempting to validate this for a ‘production’ ready state. If possible, I’d just like to ask the community if they have encountered a similar setup, and how they solved it? Thanks in advance!!!

Kamailio Authentication failing
by Eric Koome 16 Sep '16

16 Sep '16

Hi all - my Kamailio - 4.1.6 is receiving this particular structured INVITES from multiple IPs, and for some reason it is not requesting authentication. I have AUTH & IPAUTH modules in use for two years now, but this is bypassing that and actually forwarding the invite to asterisk servers behind Kamailio. I notice from the invite that the contact (c=IN IP4 10.10.10.10) is unusual and in the private range. Is this what is bypassing Authentication? Any Pointers on how to stop this. This is flooding my boxes! ========================================== 2016/09/16 06:45:16.824768 83.48.28.27:63029 -> MYPUBLICIP:5060 INVITE sip:9441134018000@MYPUBLICIPSIP/2.0 Via: SIP/2.0/UDP 83.48.28.27:5060;branch=z9hG4bK898408493 Max-Forwards: 70 From: "442030930112" <sip:442030930112@83.48.28.27>;tag=5044916148 To: <sip:9441134018000@MYPUBLICIP> Contact: <sip:442030930112@83.48.28.27> Call-ID: 9xCjfQkrmDwT7D6AqM0BTYAgmWjG84nq CSeq: 102 INVITE User-Agent: SIP Call Date: Fri, 16 Sep 2016 05:45:48 +0000 Allow: INVITE, ACK, CANCEL, OPTIONS, BYE, REFER, NOTIFY, INFO, MESSAGE Supported: replaces, timer Content-Type: application/sdp Content-Length: 308 v=0 o=442030930112 8982 1536 IN IP4 10.10.10.10 s=SIP c=IN IP4 10.10.10.10 t=0 0 m=audio 14806 RTP/AVP 0 3 8 4 18 101 a=rtpmap:0 PCMA/8000 a=rtpmap:3 GSM/8000 a=rtpmap:8 PCMU/8000 a=rtpmap:4 G723/8000 a=rtpmap:18 G729/8000 a=rtpmap:101 telephone-event/8000 a=fmtp:101 0-16 a=ptime:20 a=sendrecv Regards Eric

http_async_query - How to Allow SIP transaction to continue
by Jonathan Hunter 16 Sep '16

16 Sep '16

Hi Guys, I am just testing with jansson and http_async_query. Essentially I sent an INVITE into kamailio ,it hits CALL_START_REQUEST (see below) and the query allows the http site I send to, to provide routing details for kamailio. Logging the $rm that hits CALL_START_ REQUEST, it shows as INVITE, however when CALL_START_REQUEST_REPLY is hit, the message type is OPTIONS, is this expected behaviour? Essentially I want it to continue in the script with the same $ci,$rm so I can onwards route it for termination, but all I get are options messages being sent, any hints please? As Ideally I want the transaction to continue to a route where I can forward on modified request for termination. Thanks Jon Routes; # Send to FreeSWITCHroute[CALL_START_REQUEST]{xlog("L_INFO","route[CALL_START_REQUEST] Call received $ci,$rm,$ru,$du\n"); ###Build JSON request to send to MAP$var(params) = $null;jansson_set("string", "username", "xxx", "$var(params)");jansson_set("string", "password", "xxx", "$var(params)");jansson_set("string", "source", "$fU", "$var(params)");jansson_set("string", "route", "$var(carriername)", "$var(params)");jansson_set("string", "destination", "$rU", "$var(params)");/// other fields set herehttp_set_timeout(5000);http_set_method("POST");http_append_header("Content-Type: application/json");http_async_query("http://test.com", "$var(params)", "CALL_START_REQUEST_REPLY");xlog("L_INFO", "Checking here we have status=$var(status)\n");xlog("L_INFO", "Current Destination is $du\n");#return;#exit;}#########################route[CALL_START_REQUEST_REPLY]{xlog("L_INFO", "route[CALL_START_REQUEST_REPLY]: $ci,$rm,$ru,$du\n"); Logs show; route[CALL_START_REQUEST] Call received b087fa53-f5fc-1234-94ac-f68eb8da94f7,INVITE,sip:441624891676@8.8.8.8:5060;user=phone,<null> route[CALL_START_REQUEST_REPLY]: 123,OPTIONS,sip:G711A-282951200@kamailio.org,sip:G711A-282951200@8.8.8.8:5080

Branch variables in branch_failure_route
by Paul Smith 14 Sep '16

14 Sep '16

Hi, I am struggling to figure out variable scope in branches and branch_failure_routes. Is there a way to store a variable in a branch route so that I can then read it from the branch failure route if that branch fails? Also does writing $ru in branch_failure_route append a branch? For example I have multiple SIP devices registered to Kamailio on the same account credentials. The devices are behind same NAT, so same public IP. Some devices have SRTP required and some cannot use SRTP at all, Kamailio does not know in advance of the call whether the call will use SRTP or RTP. When I send a call to that user Kamailio correctly parallel forks to all the registered devices. I use rtpengine offer to send SDP with RTP/SAVP in the initial invites. If one of the devices sends a 488 due to not being able to handle the RTP/SAVP I then want to run rtpengine_offer with RTP/AVP and send another invite to the same device. In the branch failure route I seem to have to read the current $ru and then write it back into $ru before calling t_relay() or I get Sep 14 14:56:06 registrar-secure /usr/sbin/kamailio[10168]: ERROR: tm [t_fwd.c:1771]: t_forward_nonack(): ERROR: t_forward_nonack: no branches for forwarding This code seems to work, but it feels like I’m doing something very wrong…. in particular $avp(triedrtpout) is set for the transaction, I should be setting it separately for each branch. event_route[tm:branch-failure:SRTP] { # Handle failure response xlog("L_INFO", "Handling $T_reply_code response to $rm to ru: <$ru> and du: $du\n"); if(t_check_status("488") && is_method("INVITE")) { if ($avp(triedsrtpout)==1) { # set $ru seems to create a new branch ... even when we set it to its current value. # we want to generate a new SIP INVITE to the same AOR but with different SDP $avp(buffer)=$ru; $ru=$avp(buffer); xlog("L_INFO","488 caught. Resending to $ru"); # try with unencrypted RTP/AVP rtpengine_delete(); rtpengine_offer("to-tag trust-address replace-origin replace-session-connection ICE=force RTP/AVP"); if (!t_relay()) { sl_reply_error(); } } } } I am using kamailio 4.2 debian package for this registrar. Sorry for the rambling question … I don’t understand enough to write the short version! Paul

jansson_get path to access a JSON reponse containing an array
by Jonathan Hunter 14 Sep '16

14 Sep '16

Hi guys, Sorry for the question but Its not clear to me using json_path and the jansson module how to get the contents of a response containing an array. Please see the returned response below that I am getting on kamailio; {"status":"success","destination"[{"msisdn":"4412345566","route":"Carrier1"}],"maxduration":"60","source":"447777777","message_id":"c41c1823aafb80f44620f4cdc6802c0d"} I can access any of the fields status,destination,maxduration,source,message_id fine, however you will notice with destination it has an array (as multiple destinations with other queries could return more than one choice). So currently when I do jansson_get_field("$http_rb", "destination", "$var(mapdestination)"); I get; [{"msisdn":"447107110194","route":"carrier1"}] How do I get into the contents of the array in the first place so I can return the msisdn value itself, and the route? This is not a problem if its not an array, however if the result is contained within [] how do I indicate the path? I have tried destination[0], destination.msisdn with no luck, and Im sure I am missing something so any advice would be great. Thanks Jon

Planning the release of Kamailio v4.4.3
by Daniel-Constantin Mierla 14 Sep '16

14 Sep '16

Hello, now that the summer in the northern hemisphere is gone and many of us returned at the work, I am considering to release a new version of Kamailio out of the latest stable branch 4.4. The plan is to have it out next week, either on Wednesday Sep 14 or Thursday, the following day. If the are issues not reported on the bug tracker from github project, it is better to open one item. Do it also if you reported something on sr-users or sr-dev in the past two months and it is not actual discussion about it, likely it was forgotten or not noticed during the holidays and digesting the archive is going to take a while.

Kamailio as Proxy with public and private interface
by gmele 13 Sep '16

13 Sep '16

Hello, we are building a new SIP service composed by a 2 SIP Proxies and 2 SIP Registrars. There is only one proxy active (controlled by keepalived). To secure our SIP infra, we have decided to publish a TLS public interface on the proxy side. The SIP registrar will not be reachable from the outside, so we have added a provate interface on the SIP proxy and another one on the SIP registrar (192.168.1.x). In brief: SIP Proxy, 2 I/F, 213.xxx.xxx.xxx (TLS public) and 192.168.1.x (UDP private) SIP Registrar, 1 I/F, 192.168.1.x (UDP private). Is this architecture possible with kamailio? We tried to implement this, but it seems that all requests incoming from the public IP address are correctly routed to the SIP registrar, but with the public IP instead of the private one, resulting in the impossibility to send the SIP requests to the registrar. Should we add a VIA toute in the SIP message before forwarding it to the SIP registrar? How can this be done? Thx for your help Giovanni -- View this message in context: http://sip-router.1086192.n5.nabble.com/Kamailio-as-Proxy-with-public-and-p… Sent from the Users mailing list archive at Nabble.com.

Dump running config out of Kamailio into a file

Hi, I currently have a situation with my Kamailio servers sitting in production, the folder containing all configuration files at /etc/kamailio was deleted from the server and there is not backup. Is there a possibility to show or dump the current running configuration into a file so I could restore the configuration file from it. If it happens these servers get restarted then we are going to be in real trouble. Thanks for your help Kind regards, Albert T.

pua_dialoginfo: Tags only in "early" state PUBLISH
by Stefan Kohlhauser 12 Sep '16

12 Sep '16

Hello everyone! I've been playing around with the pua_dialoginfo. I noticed that the From- and To-Tags are only included in the PUBLISH's dialog-info of the "early" state. This is also true if include_tags of pua_dialoginfo is explicitly set to '1'. The reason for this behaviour is probably that in pua_dialoginfo.c in the function __dialog_sendpublish() the call to dialog_publish_multi() only happens with the tag parameters set for the "early" state. For all other dialog states the tag parameters are statically set to '0'. Even though the local- and from-tags are optional I tend to regard this as a bug. I would have expected for the tags to be included in the dialog-info for all states when include_tags is set. Or is there a reason for this behaviour? Best regards Stefan

The best way to see what is happening is to capture some packets on the Kamailio system on which calls happen and see if any IP address or port number issues exist in body of SIP messages or not.

Kamailio - Multiple NAT
by Marino Mileti 12 Sep '16

12 Sep '16

Hi guys, i'm going in trouble with multinat scenario and Kamailio J I've this scenario... Two kamailio boxes with the same configuration (KAM_A and KAM_B). Each box has a WIFI in AP_MODE with the same address (but different SSID obviously) 192.168.254.1. Finally there are 2 clients...CLIENT_1 connected to wifi with KAM_A, and CLIENT_2 connected using wifi with KAM_B. Each box has an instance of RTPEngine configured. KAM_A & KAM_B are also connected using wired connection with other clients in order to allow that a calls to KAM_B (or KAM_A) generate a forking scenario and all clients connected starts to RINGS (wired & wireless client) The mobile client connected on KAM_A makes a call to KAM_B... the forking scenario starts and all clients on KAM_B starts to ring. If any wired client pick up the call everything works fine. If a wireless client pick up the call...no media L Is it possible? Should I've to instruct RTPENGINE in any particular mode?

Advice for routing and sbc functions
by Oliver Roth 12 Sep '16

12 Sep '16

Hi all I am using kamailio for several years now and I am really happy with it! Now an new scenario to solve: Sip-carrier A --> Kamailio loadbalancer --> multiple kamailio routing gateways --> freeswitch/sbc/media-gw/whatever --> sip - carriers B,C & D Kamailio gateways: They are doing different checks, manipulate the numbers (national /international format) and they use the carrierroute module freeswitch/sbc/media-gw/whatever: how can I use these services with the routing information from the carrierroute module? These media-gws will do the connection and maybe transcoding to the carriers. Can you please help me with the interaction within the systems "routing gateways" and the "media/sbc gateways"? Do I have to add all the carriers in the carrierroute as "routes" with the ip of the media gw/freeswitch and then splitting it up on the freeswitch again? Thanks for helping Oli

4.4 topos ignoring Record-Route?
by Daniel Tryba 09 Sep '16

09 Sep '16

Looking into the topos module of 4.4.2 I see something unexpected, ACK and BYE are routed directly to the Contact in the 200 OK on an INVITE where the 200 OK has a Record-Route. Without the topos module the message flow is as expected: 109.235.32.57<->185.61.68.106<->109.235.32.55 With topos the ACK and BYE take a different route: 109.235.32.57<->185.61.68.106<->109.235.32.55 <->109.235.32.48 109.235.32.5x are proxies. 185.61.68.106 is the registrar To my understanding, in the callflow below the ACK should be send via the proxy that inserted Record-Route: <sip:109.235.32.55;lr> in the 200 OK. Am I wrong to conclude this or the topos module ignoring the routing? Also note the To/From are passed untouched in the ACK/BYE and the BYE to the called endpoint hasn't had its Via headers stripped. Call scenario: tryba/+31407110xxx calls 0880100XXX. Both are registered to 185.61.68.106 via proxies (resp. 109.235.32.57 and 109.235.32.55) >From 109.235.32.57 -> 185.61.68.106: INVITE sip:0880100XXX@sip.itco.nl SIP/2.0 Record-Route: <sip:109.235.32.57;r2=on;lr> Record-Route: <sip:109.235.32.57;transport=tcp;r2=on;lr> Via: SIP/2.0/UDP 109.235.32.57;branch=z9hG4bK7dd7.e15a4ffb2c3a7f882117b80c85f75223.0;i=60c Via: SIP/2.0/TCP 10.0.3.169:5067;rport=5067;received=109.235.34.226;branch=z9hG4bKb5004b60de287221 Route: <sip:109.235.32.57;transport=tcp;lr> From: <sip:tryba@sip.itco.nl>;tag=576aff337d33fbe5 To: <sip:0880100XXX@sip.itco.nl> Contact: <sip:tryba@10.0.3.169:5067;transport=tcp;alias=109.235.34.226~5067~2> >From 185.61.68.106 -> 109.235.32.55: INVITE sip:+31880100XXX@109.235.32.48 SIP/2.0 Via: SIP/2.0/UDP 185.61.68.106;branch=z9hG4bK7dd7.d4cdfe8014e0d5d806b4dc4a7422c8e0.1 Route: <sip:loadbalancer@109.235.32.55;lr;received=sip:109.235.32.48:5060> From: <sip:+31407110XXX@sip.itco.nl>;tag=576aff337d33fbe5 To: <sip:+31880100XXX@sip.itco.nl> Contact: <sip:btpsh-57b6cc75-f42d-1@185.61.68.106> >From 109.235.32.55 -> 185.61.68.106: SIP/2.0 200 OK Via: SIP/2.0/UDP 185.61.68.106;rport=5060;branch=z9hG4bK7dd7.d4cdfe8014e0d5d806b4dc4a7422c8e0.1 Record-Route: <sip:109.235.32.55;lr> From: <sip:+31407110XXX@sip.itco.nl>;tag=576aff337d33fbe5 To: <sip:+31880100XXX@sip.itco.nl>;tag=as61fc6a47 Contact: <sip:%2b31880100XXX@109.235.32.48> >From 185.61.68.106 -> 109.235.32.57 SIP/2.0 200 OK From: <sip:tryba@sip.itco.nl>;tag=576aff337d33fbe5 To: <sip:0880100XXX@sip.itco.nl>;tag=as61fc6a47 Via: SIP/2.0/UDP 109.235.32.57;branch=z9hG4bK7dd7.e15a4ffb2c3a7f882117b80c85f75223.0;i=60c,SIP/2.0/TCP 10.0.3.169:5067;rport=5067;received=109.235.34.226;branch=z9hG4bKb5004b60de287221 Contact: <sip:atpsh-57b6cc75-f42d-2@185.61.68.106> Record-Route: <sip:109.235.32.57;r2=on;lr>,<sip:109.235.32.57;transport=tcp;r2=on;lr> >From 109.235.32.57 -> 185.61.68.106: ACK sip:atpsh-57b6cc75-f42d-2@185.61.68.106 SIP/2.0 Via: SIP/2.0/UDP 109.235.32.57;branch=z9hG4bK7dd7.a49ec0c055166a1935ff84cfca4d1a5c.0;i=60c Via: SIP/2.0/TCP 10.0.3.169:5067;rport=5067;received=109.235.34.226;branch=z9hG4bK24aff2df2ee7b43f From: <sip:tryba@sip.itco.nl>;tag=576aff337d33fbe5 To: <sip:0880100XXX@sip.itco.nl>;tag=as61fc6a47 Contact: <sip:tryba@10.0.3.169:5067;transport=tcp;alias=109.235.34.226~5067~2> >From 185.61.68.106 -> 109.235.32.48 ACK sip:%2b31880100XXX@109.235.32.48 SIP/2.0 Via: SIP/2.0/UDP 185.61.68.106;branch=z9hG4bK7dd7.ac1b9a45042f9c26277afb9ec32bebe0.0 From: <sip:tryba@sip.itco.nl>;tag=576aff337d33fbe5 To: <sip:0880100XXX@sip.itco.nl>;tag=as61fc6a47 Contact: <sip:btpsh-57b6cc75-f42d-1@185.61.68.106> >From 109.235.32.57 -> 185.61.68.106 BYE sip:atpsh-57b6cc75-f42d-2@185.61.68.106 SIP/2.0 Via: SIP/2.0/UDP 109.235.32.57;branch=z9hG4bK4dd7.24da86af0a970ee399c9504933d8d751.0;i=60c Via: SIP/2.0/TCP 10.0.3.169:5067;rport=5067;received=109.235.34.226;branch=z9hG4bK0d8db1380c5011b6 From: <sip:tryba@sip.itco.nl>;tag=576aff337d33fbe5 To: <sip:0880100XXX@sip.itco.nl>;tag=as61fc6a47 >From 185.61.68.106 -> 109.235.32.48 BYE sip:%2b31880100XXX@109.235.32.48 SIP/2.0 Via: SIP/2.0/UDP 185.61.68.106;branch=z9hG4bK4dd7.4916bf7bcaa3b0346e43c3785a9be782.0 Via: SIP/2.0/UDP 109.235.32.57;branch=z9hG4bK4dd7.24da86af0a970ee399c9504933d8d751.0;i=60c Via: SIP/2.0/TCP 10.0.3.169:5067;rport=5067;received=109.235.34.226;branch=z9hG4bK0d8db1380c5011b6 From: <sip:tryba@sip.itco.nl>;tag=576aff337d33fbe5 To: <sip:0880100XXX@sip.itco.nl>;tag=as61fc6a47

Video calls with delay on one side
by Yuriy Gorlichenko 09 Sep '16

09 Sep '16

Hi. I usein kamailio 4.4 +rtpengine 4.5 for making videocalls though Web And have issue with it: I have one way audio and video till video not started. For example i calling form A point to B point B point accept call and have Audio and Video flow from the point A but point A have no any media flow. For now i using scheme when kamailio runs together with asterisk but also i had this issue with calls without asterisk. There is a link on issue i discribed before https://github.com/sipwise/rtpengine/issues/260 I use settings at the kamailio rtpengine_manage("force trust-address replace-origin replace-session-connection RTP/SAVPF") for making UDP call to WS And rtpengine_manage("trust-address replace-origin replace-session-connection ICE=remove DTLS=passive RTP/AVP media-address=MY_IP_ADDR"); For converting to back I use folloving scheme (Call from A to B) WSphone(A)->(1-st leg)-> kamailio+rtpeinge->(2-nd leg->)asterisk asterisk ->(3-st leg)-> kamailio+rtpeinge->(4-th leg)->WSphone(B) At the example below rtpengine (with kamailio) an asteirsk uses same server But connection made thoufh external interface. not local (it is made because in a production scheme asteirsk will be in a different server, but actuaaly it is does not have any matter, just for understanding topology) So at the logs after call i see next things First call from point A to asterisk (first leg and second leg) [1473403379.000108] INFO: [ga5c8qb2uaasr42j63h4]: ------ Media #1 <https://github.com/sipwise/rtpengine/issues/1> (audio over RTP/SAVPF) using

my.ser.ver.ip:30156 (type 111, len 000071) Sent RTP P2P packet to my.ser.ver.ip:30238 (type 107, len 000079) when packets sended from asterisk to rtpengine they have no response So it looks like that asterisk have no response from rtpengine when sending him any IP. Also i checked at the webphone side but it sending pakents. So at this side no trouble... Thanks for advices!

Call forking with delay
by Igor Potjevlesch 08 Sep '16

08 Sep '16

Hello list, I have a proxy that manage fix calls and a proxy that manage mobile calls. I want to implement call forking so when I call to a fix phone the call goes to the fix proxy and it forks to the mobile proxy who manage the call and viceversa. I want the fix to ring 2 or 3 times before the mobile. In order to do so in my fix proxy I added a diversion field with the reason "forking" and in my mobile proxy I check if the reason is "forking" to wait with the fonction "async_route" from the ASYNC module. When I call the fix I can fork to the mobile with delay without any problem because in that case my fix proxy manage one call and my mobile proxy the other one. But when I call the mobile the call doesn't even get to my fix proxy because my mobile proxy has to make the original call to wait while he is forking the fix call to my other proxy. And i think that calling the async_route fonction makes both calls to wait. My code is: Fix proxy: if($tU==123456789){ add_diversion("forking"); append_branch("sip:987654321@proxy_mobile"); } Mobile proxy: if($tU==987654321){ $var(z) = "1"; append_branch("sip:123456789@proxy_fix"); } route[INVITE]{ if($dir == "forking"){ async_route("RELAY", "7"); }else if($var(z) == "1"){ async_route("RELAY", "7"); }else{ route(RELAY); exit; } } How can I differentiate in the second scenario when I call the mobile phone to fork to the fix phone? Thank you for your help. Igor.

Hi. I try to make working kamailio on TCP infront of asterisk Before to send to asteisk any packet i added $fs=ip.add.re.ss:port Also discribed listen=tcp:ip.add.re.ss:port But kamailio send outgoing packets from random prot throug TCP Presume i configured 5060 port but it send from 35410 port. googling on a core functions didn gives me any answer. May be i forget something to set at the config?

UAC reg_contact_addr with rinstance
by DanB 08 Sep '16

08 Sep '16

Hey Guys, Have hit an issue when using uacreg. When working with Broadsoft (I know, life is not perfect), it appears that their SBC sitting in front of registration server is caching REGISTRATION requests and it will not be able to re-REGISTER in case of credential changes for example. This will break the registration process in registrar since that one flushes the registrations on password change. Their "standard" workaround it is using "rinstance" uri parameter in contact (each contact should be unique in order to be cached by their SBC). Checking it appears that I can only add rinstance statically in reg_contact_addr configuration parameter. Is there any chance to provide things like $avp or selects which I can later modify via mi maybe? Thanks in advance for any kind of tip! DanB

Query - REST API calls in async
by Agalya RAMACHANDRAN 08 Sep '16

08 Sep '16

Hi team, I am Agalya and I work for Comcast. We are trying to use kamailio as proxy server for our project. I have a query regarding the same. We are trying to use REST API calls asynchronously from the config file. I see that there is a module "http_async_client" which is used to handle REST services asynchronously. Found that libcurl is used to perform these operations. My question is: 1) How much time kamailio is taking to send the HTTP request out after TCP port is opened? Is there any time dependency we need to wait on libcurl to send HTTP request out? B'coz in opensips I see a delay time and libcurl is used in-turn. I found kamailio doing similar to opensips and hence am posting this question. 2) We can also use PUT service by using http_set_method(PUT)? Should we add code to support PUT service? Thanks in advance. Regards, Agalya

Mitigating DDOS attacks from carrier based on ani or dnis by limitating cps or blocking when detecting
by anfecora 08 Sep '16

08 Sep '16

Hi is there any way to use pike and htable to mitigate ddos or flood attack from trusted trunks. I need help to build it the same way kamailio control registrations. Case a carrier trunk star calling several users from the system to more than 50 CPS(calls per second), it will affect the system but cannot block the trunk since it is pstn traffic coming from a sip provider, therefore we need to find a way to identify this traffic based on ANI or DNIS or any other header and then blocked for a time just like pike does with registrations, then start the cycle all over. in less words make kamailio be aware of invite request rate, then verify that is from the same source means ani or dnis then tagged as bad traffic them star dropping it for a specified time, while normal traffic still flowing unaffected. any recommendations will be highly appreciated. thank you

Resume suspended invite transation after x seconds
by José Seabra 06 Sep '16

06 Sep '16

Hello, I have the following scenario: Kamailio is suspending an INVITE then generates a SUBSCRIBE msg to an external server with UAC module, and only resume the suspended INVITE when receives an NOTIFY(this NOTIFY "belongs" to the SUBSCRIBE dialog) from the external server. The issue is that sometimes kamailio doesn't receive a NOTIFY and the transaction is not resumed, any one have an idea how can i implement a solution to resume the suspended invite after x seconds without receiving NOTIFY msg? Best Regards -- José Seabra

detect failed socket
by Péter Barabás 05 Sep '16

05 Sep '16

Hello, I want to refine the instant message handling in our application. It works really fine in most cases. I use the msilo module to store offline messages if the user is not registered with sending PUSH notification. But, there is a situation when I have problems: When I send a message to a user whose phone is in airplane mode. In this case his location record exists but the communication on the socket is not possible and the client timed out the request. Is it possible to check the socket towards the receiver user at the moment when the message arrives at Kamailio? I think if I would check that if the socket is not fine, I could send the message to the msilo directly and the client would not have wait for timeout to resend. Thanks. Peter

Just dont know what i need to change. I will be very grateful if someone heps me to resolve this issue. Thanks

Kamailio - passing registration to another sip server
by Mike Patterson 05 Sep '16

05 Sep '16

I have configured Kamailio to pass a registration request to another VoIP provider. The reason I am doing this is to provide a sip port for users where the ISP is blocking SIP. I am able to pass the registrations to the VoIP provider but I'd like to have inbound calls working as well. I see the inbound invites coming into the Kamailio server but it appears that the server does not 'know' about the UA that is registered 'through' the server to the VoIP provider. Can anyone tell me how to fix this problem? Below is my config. Thank you, Mike #!KAMAILIO # # Edge proxy configuration # #!subst "/REGISTRAR_IP/xxxxxxxxxx/" #IP address of voip provider #!subst "/REGISTRAR_PORT/5060/" #!substdef "/FLOW_TIMER/20/" debug=2 log_stderror=no log_facility=LOG_LOCAL0 fork=yes children=4 alias="example.com" #mpath="/usr/lib64/kamailio/modules" mpath="/usr/lib/x86_64-linux-gnu/kamailio/modules" tcp_connection_lifetime=30 # FLOW_TIMER + 10 auto_aliases=no mhomed=0 listen=udp:X.X.X.X:531 advertise X.X.X.X:531 alias="X.X.X.X:531" alias=X.X.X.X:531 alias="X.X.X.X:531" alias=X.X.X.X:531 port=531 ####### Modules Section ######## loadmodule "tm.so" loadmodule "sl.so" #loadmodule "outbound.so" loadmodule "rr.so" loadmodule "path.so" loadmodule "pv.so" loadmodule "maxfwd.so" loadmodule "xlog.so" loadmodule "sanity.so" loadmodule "ctl.so" loadmodule "mi_rpc.so" loadmodule "mi_fifo.so" loadmodule "textops.so" loadmodule "siputils.so" loadmodule "rtimer.so" loadmodule "sqlops.so" # ----------------- setting module-specific parameters --------------- # ----- mi_fifo params ----- modparam("mi_fifo", "fifo_name", "/tmp/kamailio_fifo") # ----- tm params ----- modparam("tm", "failure_reply_mode", 3) # ----- rr params ----- modparam("rr", "append_fromtag", 0) ####### Routing Logic ######## request_route { route(REQINIT); if (is_method("CANCEL")) { if (t_check_trans()) { route(RELAY); } exit; } route(WITHINDLG); t_check_trans(); if (is_method("REGISTER")) { remove_hf("Route"); add_path(); $du = "sip:REGISTRAR_IP:REGISTRAR_PORT"; } else { if (is_method("INVITE|SUBSCRIBE")) record_route(); if ($si == "REGISTRAR_IP" && $sp == "REGISTRAR_PORT") { if (!loose_route()) { switch($rc) { case -2: sl_send_reply("403", "Forbidden"); exit; default: sl_reply_error(); exit; } } t_on_failure("FAIL_OUTBOUND"); } else { if ($rU == $null) { sl_send_reply("484", "Address Incomplete"); exit; } remove_hf("Route"); $du = "sip:REGISTRAR_IP:REGISTRAR_PORT"; } } route(RELAY); } route[RELAY] { if (!t_relay()) { sl_reply_error(); } exit; } route[REQINIT] { if (!mf_process_maxfwd_header("10")) { sl_send_reply("483","Too Many Hops"); exit; } if(!sanity_check("1511", "7")) { xlog("Malformed SIP message from $si:$sp\n"); exit; } } route[WITHINDLG] { if (has_totag()) { if (!loose_route()) { switch($rc) { case -2: sl_send_reply("403", "Forbidden"); exit; default: if (is_method("ACK")) { if ( t_check_trans() ) { route(RELAY); exit; } else { exit; } } sl_send_reply("404","Not Found"); } } else { if (is_method("NOTIFY")) { record_route(); } route(RELAY); } exit; } } onreply_route { if (!t_check_trans()) { drop; } if ($rm == "REGISTER" && $rs >= 200 && $rs <= 299) { remove_hf("Flow-Timer"); if ($(hdr(Require)[*])=~"outbound") insert_hf("Flow-Timer: FLOW_TIMER\r\n", "Call-ID"); } } failure_route[FAIL_OUTBOUND]{ if (t_branch_timeout() || !t_branch_replied()) { send_reply("430", "Flow Failed"); } }

VUC - SER-Kamailio At 15 Years - On Friday, Sep 2, 2016
by Daniel-Constantin Mierla 02 Sep '16

02 Sep '16

Hello, on September 3, 2001, the first line of code was committed to SIP Express Router (SER) project, since 2008 turning into Kamailio project. >From pioneering large scale deployments of using SIP for Voice over IP in early 2000s, the project impacted the evolution of real time communications, disrupted the telecom vendors with its open source model and enabled many businesses to grow and innovate. Let's get together to a VUC session later this week, on Friday, Sep2, 2016, to share the good or bad stories while using SER or Kamailio during the past 15 years. If it made your life easy or a nightmare, it's time to tell it. If you have a funny photo or video, no matter is old or recent, join us and show it. More details about VUC and how one can join or watch the session are available at: - https://vuc.me If you want to actively participate during the session, email me shortly to coordinate a bit. If you cannot participate but you have something interesting to share (story, media files, etc...) email me as well and I will present it. Cheers, Daniel -- Daniel-Constantin Mierla http://www.asipto.com - http://www.kamailio.org http://twitter.com/#!/miconda - http://www.linkedin.com/in/miconda

Kamailio with Dispacher
by Rodrigo Moreira 02 Sep '16

02 Sep '16

Hello, I would like to clarify a question. Can you help me? I'm deploying a solution based on Kamailio, but I need incorporate the load balancer funcionality in the environment. See the cenario: I have five VMs. PCSCF, ICSCF, SCSCF, HSS, DNS. Each VM runs the especific funcionality of the IMS. Therefore, which machines should receive the config provided by dispacher module? Is the PCSCF? Another question: The DNS server should be updated, I may do this previously? The HSS, should be updated too, I may do this previously? Do you known about approaches of the LB available? Best Regards. Thanks. -- Rodrigo M. (37) 9132-4539 (34) 9889-3069 rodrigo.moreira2007

issue with memcached module
by jay binks 02 Sep '16

02 Sep '16

if I use the memached module in kamailio to set STRING data in memcache, this is not readable from PHP. This is because kamailio uses the "val_flag" to distinguish the type of data ( int or string ). There does not appear to be a standard for how data type is indicated ( in fact the protocol doc for memcache says "<flags> is an arbitrary 16-bit unsigned integer" ) I think the memcache module really needs a way to let the user specify the value of the flag. something like a modparam to override the flag value on every set. has anyone else run in to this ? Sincerely Jay Binks

Domain limits and domain.reload
by Bruno Emer 01 Sep '16

01 Sep '16

Hello all. I am currently working in a company that built an online platform that allows companies talk to their customer using different medias, such as video, voice and chat. To this, we are using Kamailio to provide SIP services such as WebSockets, Registrar and proxy, and ir works really well. The point is that today we are creating a new domain for each company that uses our system, and for now we have more than 3k companies using it, so my first question is: is there a limit about how many domains we can create in a Kamailio environment? I tried to find this on the documentation but I haven't found anything. Second: every time that we create a new domain, we perform a domain.reload using the XMLRPC module. We are just using the python script to do this, but sometimes it is returning the error: Fault 400: 'Reload of domain tables failed' and we don't know why. The strange thing is that if we access the server and execute a 'kamctl domain reload' just after the error, everything works fine. The problem appears to be in the RPC module. So the question is: does someone knows what can be the cause of this problem? Thanks. *Bruno Emer* Mobile: +55 11 96540-0044 email: brunoemer(a)gmail.com <https://www.facebook.com/bruno.emer.5> <https://www.linkedin.com/profile/view?id=86461237&trk=spm_pic> <https://twitter.com/brunoemer_> <https://www.flickr.com/photos/122070309@N03/> <http://google.com/+BrunoEmer> <http://instagram.com/brunoemer_>

Htable keys and key::size inconsistencies
by Fabian Borot 01 Sep '16

01 Sep '16

Hi, I am using htable module with version 4.4 storing multiple values in the same key (I set the key_type = 1 for each entry, array key). I have found an issue with the htable module. Some keys show up when using: "./kamcmd htable.get my_table key[0]" but when asking for the "key::size" I says that the key does not exist. Also some entries have the "key::size" entry but the actual "key[0]" for example is reported as non existent: See these 2 examples: Ex:1 "key[0]" is shown but "key::size" is not: [root@ar-mia-proxy-01 sbin]# ./kamcmd htable.get htable_lcrgwA 8[0] { item: { name: 8[0] value: 555|5875|1.1.1.1|5060|0|4|1|1|Broadvox2010IN flags: 2 expire: NEVER } } [root@ar-mia-proxy-01 sbin]# ./kamcmd htable.get htable_lcrgwA 8::size error: 500 - Key name doesn't exist in htable. Ex2: "key::size" is shown but "key[0]" is not: [root@ar-mia-proxy-01 sbin]# ./kamcmd htable.get htable_lcrgwA 9[0] error: 500 - Key name doesn't exist in htable. [root@ar-mia-proxy-01 sbin]# ./kamcmd htable.get htable_lcrgwA 9::size { item: { name: 9::size value: 6 flags: 0 expire: NEVER } } Also, for this case "9::size", supposedly there are 6 entries and in reality there are only 4 in the tables where I am loading them from For the case "8::size" that returns 2 the count it is right , the prob is that I can not get the "8[0]" and "8[1]" keys Any ideas are very appreciated, thank you

kamailio outgoing gateway
by Andrzej Kaczmarczyk 31 Aug '16

31 Aug '16

I have common, cheap TL-WR1043ND V1 router. For private purposes I've set kamailio voip on my own server INSIDE my LAN. Is it possible to connect to that server from outside, through openWRT router? Many tries, no success - too many jumps or something similar. I guess router should be fully transparent for sip protocol. How to manage it? is it possible at all? I don't ask how to do it in details on my router/openwrt (but if someone knows, it will be nice), but - is this possible to setup at all? should I try or search for resolution, or just give up with that idea? -- Pozdrawiam Andrzej Kaczmarczyk

Looking for network version of ds_reload
by Chad McElligott 30 Aug '16

30 Aug '16

Hello all, I'm in the process of converting an on-host install of Kamailio to be run inside a docker container. A part of this Kamailio install is a small node.js application that modifies the sqlite database Kamailio uses, then runs `kamctl fifo ds_reload` to tell Kamailio to reload its knowledge from that database. I'm trying to split these two processes (the node app and the Kamailio server) into separate docker containers, in an effort to follow the one-process-per-container philosophy, but having trouble figure out exactly how I should perform the ds_reload step without access to the kamctl in the Kamailio container. The obvious direction that I'm looking is to perform some sort of network request, since I can configure the two docker containers to have network access to each other. Is there some way to perform a ds_reload over the network? Thanks for all you do. Kamailio is a great SIP server and we use it to great effect. -Chad McElligott

uac_auth and (serial) forking
by Daniel Tryba 30 Aug '16

30 Aug '16

Trying to implement a way to authenticate outgoing INVITEs to endpoints that need/want to. uac_auth in the initial failure route works fine when there is only 1 registered user to send the INVITE to. But with at least 2 locations are available and 1 accepts the INVITE without authentication, the 401 of the location that wants authentication isn't processed in the failure route until a timeout is triggered (t_set_fr). At that point the 401 is processed and a response generated with Authentication header. But since t_set_fr invite timeout was exceeded it is immediatly destroyed due to a CANCEL having been generated to the location(s). t=0: t_set_fr(10000); INVITE to A anb B A responds 100 Trying,180 Ringing B responds 401 Unauthorized t=10s: T_code=180, new_code=408 failure route status: 401 uac_auth() INVITE with Authorization is build to B CANCEL to A INVITE to B is never send Is this expected behaviour? Obviously I didn't expect this.

Configuration Issue on Kamailio.
by Laura 30 Aug '16

30 Aug '16

Dear list, i'm asking here a question about Kamailio config. We are testing a wide area configuration of Kamailio over separates countries and we are still facing with an issue. We configured Kamailio 4.3.5 with dialog support over the TM modules and we use LCR module for menage ours LCRs rule set profiles. For some technicals reasons we use tech prefix for our customer so for exaples customer1 send traffic to us with 1111 prefix, customer2 send traffic to us with 2222 and something similar.. Our supplier, of course, are using tech prefix too so for examples if i want to send the call to supplier1 i need to use tech prefix 1789 or something similar.. The point is.. When customer1 is sending an invite to us.. it send us something like (Bangladesh mobile 8801xxx) INVITE sip:11118801xxxxxxx@aaa.bbb.ccc.ddd Our Kamailio will reply with the Trying and then it goes to LCR module and match our supplier1 so it make a new invite like this INVITE sip:17898801xxxxxx@supplier.ip The problem come when supplier1 reply to us and we replies back to customer1.. Customer1 view the From: field with the 17898801xxxxxx numbers.. and some of our customers don't like it. We don't use anymore the topoh module becuase we found some troubles using it.. so.. Is there a way that we can use for fix this situation ? Best regards.

Kamailio and user registration and a question on STUN servers
by Kevin Greene 29 Aug '16

29 Aug '16

Hello Group: I am looking for a way to allow any SIP client to register to my (development) network without having to be already registered in the database. Is there a way for the user client to register and create a valid user subscription in the database? The SIP clients I am using have hard coded passwords and I can not change them. I think once loaded into the database, I can delete the ones I do not want later after I close automatic registration feature... The second question is on STUN servers. Is there a good way to test to see if one is working from outside your network? I was looking for some sort of web based tool I could access to see if my public STUN server is really working. I am using the "reTurnServer" software on Linux. I am only allowing TCP based STUN requests. Thank you. Sample log entry for a external user trying to access the development network. I would like to give this person access to place calls on the system. 199.58.xxx.xxx.nebraskalink.com - - [25/Aug/2016:18:02:49 +0000] "GET /download/?ojo-mac=00:02:54:00:a5:eb&ojo-id=2000-0005-2F52&ojo-rev=rev02.01.15&ojo-config-id=e712e6cb088ab9b4ef246488b979cbf6&ojo-stun-type=Blocked&ojo-sn=15190252560146703100&ojo-key-id=e0142f126a5197845a24f33deedc358645e67e5f HTTP/1.0" 200 1812 "-" "Wget/1.9.1"

Monitor diameter state and number of current calls
by Ramiro Romero Arjona 23 Aug '16

23 Aug '16

Hi, We would like to know if there is some way to check the state of a diameter connection (to see is it's in state 6: connected), inside the kamailio configuration script. Also we would like to know if there is a way to see the number of current calls in a kamailio through kamcmd, kamctl or something like that. We have searched for a solution but we don't find anything. Many thanks.

Howto timeout INVITEs over TCP to something < 30s?
by Daniel Tryba 22 Aug '16

22 Aug '16

If an enduser INVITEted over TCP t_set_fr(t) with t < 30s have no effect, the INVITE will always timeout after 30s. What is controlling this 30s? The only default at 30s is the fr_timer, which should have no part in the timeout between an 1xx and a final answer for an INVITE.

Evapi module is not broadcasting any data

Hi folks, I came into a problem with evapi module, while I was trying to make the CGRateS tutorial work. It does not send any messages at all. Taken steps: I start kamailio with debug=3. I start: CGRates (on the kamailio machine) telnet 192.168.30.29 8448 (from my PC) tcpdump port 8448 -A -s0 -i any (on the kamailio machine) Telnet command successfully connects to kamailio.

Situation as following User --> Class5 switch --> Kamailio --> carrier I always get the ip of the class5 switch in the contact. But my carrier needs the kamailios contact ip - because of the ack handling. I replaced in the pstn routing parte the contact by remove_hf("Contact"); append_hf("Contact: <sip:xyz@a.b.c.d>\r\n"); This worked - but the bye did not work any more.

Running both 4.3 and 4.4 with the same database with permission module
by Daniel Tryba 19 Aug '16

19 Aug '16

I want to upgrade my cluster from 4.3 to 4.4, beginning with the spare for live testing. But since there is a change to the trusted table (which we don't use, only address) this isn't possible without some tricks. There is no override for skipping the version check on any permissions table. I need to share the subscriber/location/address/usr_preferences and db_aliases tables between the 4.3 and 4.4 machines. The only thing I can think of is: -patch the permissions module to accept the old version of trusted -create a 4.4 database and use federated tables to access the 4.3 data Not hard to implement any of these 2, but some other modules have the option to skip these checks, eg: http://www.kamailio.org/docs/modules/4.4.x/modules/auth_db.html#auth_db.p.v… Is there a reason not all modules have this flag (which you could use at your own risk)? Or am I missing something here?

Trouble with nat_uac_test()
by Noah Mehl 18 Aug '16

18 Aug '16

Hey all, I have a Kamailio implementation (version: kamailio 4.4.1 (x86_64/solaris) 12b048) as part of the Kazoo platform. I’m having an odd problem with an e2e ACK (after a 200OK after a T38 re-invite), which I’m pretty sure has to do with a Contact header rewrite due to the following (can review attached PCAP for specifics): if (nat_uac_test("3")) { force_rport(); fix_nated_contact(); } I have a couple of questions about this: A flag of 3, I don’t understand. I read the documentation <http://kamailio.org/docs/modules/4.4.x/modules/nathelper.html#nathelper.f.n…>, and there is a 1,2,4,8,etc… So, I’m guessing that a flag of 3, means 1+2? If #1 is true, then "the "received" test is used: address in the “Via” header is compared against source IP address of signaling” I don’t understand this test, as I’m pretty sure that the 200OK that’s getting re-written is properly constructed. I guess I’m trying to understand when one would want to use this test? Thanks! ~Noah

At this point msilo is still not active , it was obvious that I needed to add route statement. I copied the provided route statement , and edited it so will be similar to route functions that are already there. that was the outcome: # Routing to MSILO route[MSILO] { #!ifdef WITH_MSILO if ( !mf_process_maxfwd_header("10") ) { sl_send_reply("483","To Many Hops"); exit; }; if (uri==myself) { { # for testing purposes, simply okay all REGISTERs if (method=="REGISTER") { save("location"); log("REGISTER received -> dumping messages with MSILO\n"); # MSILO - dumping user's offline messages if (m_dump()) { log("MSILO: offline messages dumped - if they were\n"); }else{ log("MSILO: no offline messages dumped\n"); }; exit; }; # domestic SIP destinations are handled using our USRLOC DB if(!lookup("location")) { if (! t_newtran()) { sl_reply_error(); exit; }; # we do not care about anything else but MESSAGEs if (!method=="MESSAGE") { if (!t_reply("404", "Not found")) { sl_reply_error(); }; exit; }; log("MESSAGE received -> storing using MSILO\n"); # MSILO - storing as offline message if (m_store("$ru")) { log("MSILO: offline message stored\n"); if (!t_reply("202", "Accepted")) { sl_reply_error(); }; }else{ log("MSILO: offline message NOT stored\n"); if (!t_reply("503", "Service Unavailable")) { sl_reply_error(); }; }; exit; }; # if the downstream UA does not support MESSAGE requests # go to failure_route[1] t_on_failure("1"); t_relay(); exit; }; # forward anything else t_relay(); } failure_route[1] { # forwarding failed -- check if the request was a MESSAGE if (!method=="MESSAGE") { exit; }; log(1,"MSILO:the downstream UA doesn't support MESSAGEs\n"); # we have changed the R-URI with the contact address, ignore it now if (m_store("$ou")) { log("MSILO: offline message stored\n"); t_reply("202", "Accepted"); }else{ log("MSILO: offline message NOT stored\n"); t_reply("503", "Service Unavailable"); }; } #!endif return; } but after that I restarted kamailio service and got the following errors: root@debian:~# service kamailio restart Job for kamailio.service failed. See 'systemctl status kamailio.service' and 'journalctl -xn' for details. root@debian:~# systemctl status kamailio.service -l ● kamailio.service - Kamailio (OpenSER) - the Open Source SIP Server Loaded: loaded (/lib/systemd/system/kamailio.service; enabled) Active: failed (Result: exit-code) since Wed 2016-08-17 21:35:41 EET; 4s ago Process: 3693 ExecStart=/usr/sbin/kamailio -P /var/run/kamailio/kamailio.pid -f $CFGFILE -m $SHM_MEMORY -M $PKG_MEMORY -u $USER -g $GROUP (code=exited, status=255) Main PID: 3470 (code=exited, status=0/SUCCESS) Aug 17 21:35:41 debian kamailio[3693]: : <core> [cfg.y:3368]: yyerror_at(): parse error in config file /etc/kamailio/kamailio.cfg, line 556, column 5: bad command Aug 17 21:35:41 debian kamailio[3693]: : <core> [cfg.y:3368]: yyerror_at(): parse error in config file /etc/kamailio/kamailio.cfg, line 613, column 12: syntax error Aug 17 21:35:41 debian kamailio[3693]: : <core> [cfg.y:3368]: yyerror_at(): parse error in config file /etc/kamailio/kamailio.cfg, line 613, column 12: Aug 17 21:35:41 debian kamailio[3693]: ERROR: bad config file (5 errors) Aug 17 21:35:41 debian kamailio[3693]: WARNING: <core> [ppcfg.c:221]: pp_ifdef_level_check(): different number of preprocessor directives: N(#!IF[N]DEF) - N(#!ENDIF) = 3 Aug 17 21:35:41 debian kamailio[3693]: INFO: <core> [sctp_core.c:53]: sctp_core_destroy(): SCTP API not initialized Aug 17 21:35:41 debian kamailio[3693]: loading modules under config path: /usr/lib/x86_64-linux-gnu/kamailio/modules/ Aug 17 21:35:41 debian systemd[1]: kamailio.service: control process exited, code=exited status=255 Aug 17 21:35:41 debian systemd[1]: Failed to start Kamailio (OpenSER) - the Open Source SIP Server.

Also I tried to mimic some cfg examples like this one : http://telephonynetworks.blogspot.com.eg/2012/08/configuracion-de-kamailio-… but it uses an older version of kamailio 3.3 , and I noticed considerable changes in mpath statement, so that was unsuccessful. kamailio.cfg is attached with and without msilo route. For the experts out there Please Advise . system details : {(OS:Debian8 i386),(Kamailio4.4 with mySQL , UDP only)} Thank you all in advance. Best Regards, Eng Hooda
