Registered User limit
by Philip Fleck 17 Aug '18

17 Aug '18

Is there a limit to the number of users which can be registered on Kamailio at any one time, or a configuration file which sets this. I have just installed Kamailio in a lab environment for testing purposes but I seem to only be able to register 1024 users, all remaining Register requests are ignored. I am not using a database to authenticate users or anything, just want to be able to register upto 10,000 users. regards Philip

Bogus event 8 in state 1 for dlg
by Phillman25 Kyriacou 17 Aug '18

17 Aug '18

Hi! I keep receiving the below logs on Kamailio: CRITICAL: dialog [dlg_hash.c:955]: log_next_state_dlg(): bogus event 8 in state 1 for dlg 0x7f59862cd440 [3685:10496] I understand that state 1 indicates an unconfirmed dialog, can anyone tell me what bogus event 8 is? The following is the call flow: User A ===> Kamailio ==> Provider >From the PCAP trace an INVITE is sent to the provider, the provider answers with 100 Trying, 180 Ringing and immediately an OPTIONS message with the same call id Kamailio Provider INVITE =================> 100 Trying <================= 180 Ringing <================ OPTIONS <================ Im assuming bogus event 8 is the OPTIONS message? Is an OPTIONS message normal in this case? Thanking you very much in advance for your help! Regards Phillip

Kamailio as a P-CSCF user
by serkan celik 16 Aug '18

16 Aug '18

Hi all, I want to use Kamailio as a P-CSCF on ubuntu 18. Kamailio will be p-cscf and will communicate scscf in another open-ims box. How can I implement this feature. I have already looked following link. However it did not help me since I could not see any example pcscf configuration files after installation https://www.kamailio.org/wiki/tutorials/ims/installation-howto Regards, Serkan

how to enable tcp_write_buf?
by Juha Heinanen 16 Aug '18

16 Aug '18

I tried to issue mtree.list command using xmlrpc query that would result in large response, and got error Aug 15 18:12:07 char /usr/bin/sip-proxy[10348]: ERROR: <core> [core/tcp_main.c:618]: _wbufq_add(): (221375 bytes): write queue full or timeout (0, total 0, last write 55534052 s ago) Aug 15 18:12:07 char /usr/bin/sip-proxy[10348]: ERROR: xmlrpc [xmlrpc.c:811]: send_reply(): Error while sending reply Aug 15 18:12:07 char /usr/bin/sip-proxy[10367]: ERROR: <core> [core/tcp_main.c:3551]: handle_ser_child(): received CON_ERROR for 0x7f112ad22be0 (id 5), refcnt 3, flags 0x4018 I though that perhaps I could get rid of the error by increasing value of core var tcp_conn_wq_max. Description of the var tells: Maximum bytes queued for write allowed per connection. Attempting to queue more bytes would result in an error and in the connection being closed (too slow). If tcp_write_buf is not enabled, it has no effect. What is tcp_write_buf and how to enable it? I could not find anything about it in core cookbook. -- Juha

kamailio rtp proxy set not working
by ANOOP V M 16 Aug '18

16 Aug '18

I have installed kamailio 5.1.4 version in ubuntu server. I need to route RTP packets through kamailio with SIP packets. I will explain the way i have set up everything. I have installed rtpproxy by apt-get install rtpproxy. i have edited "/etc/default/rtpproxy" file with the line 'EXTRA_OPTS="-F -s udp:127.0.0.1:7722 -l 34.201.122.249 -d DBUG:LOG_LOCAL0"' i have edited "/etc/init.d/rtpproxy" file as follows, DAEMON=/usr/bin/$NAME PIDFILE="/run/$NAME/$NAME.pid I have provided "#!define WITH_NAT" and "modparam("rtpproxy", "rtpproxy_sock", "udp:127.0.0.1:7722")" in my cfg file. started rtpproxy "service rtpproxy start" when i try "netstat -tulpn | grep rtp" it shows udp 0 0 127.0.0.1:7722 0.0.0.0:* 1437/rtpproxy So i think the rtpproxy is currently running fine. Now we can go to kamailio part. I have gone through the document " https://www.kamailio.org/docs/modules/5.0.x/modules/rtpproxy.html" to set up rtpproxy in the cfg file. checking the rtp ports "kamcmd rtpproxy.list" showing { setid: 0 url: udp:127.0.0.1:7722 index: 0 disabled: 0 weight: 1 recheck: 0 } I have enabled rtp proxy using "kamcmd rtpproxy.enable udp:127.0.0.1:7722 1". So i think ports are ready for rtp proxy. Now i will explain the call flow. I have enabled log using L_BUG. when i try a call from hangout number through my twilio trunk to my asterisk freepbx extension, set_rtp_proxy_set("1"); giving true value. But rtpproxy_offer(); giving -1 as result. syslog shows some errors like below, Aug 13 10:28:57 ip-172-30-0-10 rtpproxy[1437]: DBUG:handle_command: received command "1934_4 Uc0,8,3,111,9,101 52001b5b71435b1c5392b39f2f6c975b@asterisk_ip:5060 asterisk_ip 14540 as4083c85f;1" Aug 13 10:28:57 ip-172-30-0-10 rtpproxy[1437]: INFO:handle_command: new session 52001b5b71435b1c5392b39f2f6c975b@asterisk_ip:5060, tag as4083c85f;1 requested, type strong Aug 13 10:28:57 ip-172-30-0-10 rtpproxy[1437]: ERR:create_twinlistener: can't bind to the IPv4 port 47926: Cannot assign requested address Aug 13 10:28:57 ip-172-30-0-10 rtpproxy[1437]: ERR:handle_command: can't create listener Aug 13 10:28:57 ip-172-30-0-10 rtpproxy[1437]: DBUG:doreply: sending reply "1934_4 E10#012" And also my header is not changed. As a result actuall rtp is going end to end between asterisk and twilio not through kamailio. Please help me with the details.

Very strange reinvite behaviour
by Alex Balashov 15 Aug '18

15 Aug '18

Hi, We have a scenario like this: ITSP -----> Kamailio -----> Endpoint (UDP) (TLS) So, TLS is only being used on the last hop, and the upstream interaction with the ITSP is plain-old UDP. Kamailio has the following listeners: listen=udp:1.1.1.1:5060 listen=udp:1.1.1.2:5060 listen=tcp:10.0.0.1:5060 listen=tls:1.1.1.1:5061 At some point, 'Endpoint' sends a reinvite which has the following RURI: INVITE sip:1.1.1.1:5061 SIP/2.0 This is clearly improper, and caused a loop that led to the rtpengine SDP loop issue I previously reported in another thread. So, in an effort to stop this, I added the following: if(has_totag()) { if(loose_route()) { ... if(is_method("INVITE")) { xlog("L_INFO", "[R-MAIN:$ci] Re-INVITE received from $si:$sp to RURI $ru\n"); xlog("L_INFO", "[R-MAIN:$ci] Reinvite body: $mb\n"); if(!is_method("ACK") && uri == myself) { sl_send_reply("400", "Bad Request"); exit; } } } But it doesn't work. It appears that the '400 Bad Request' rejection never happens, presumably because the this domain doesn't match 'myself'. Another perplexing mystery: the log message containing the reinvite's '$ru' does not show a RURI of 'sip:1.1.1.1:5061', but rather the remote target in the initial inbound INVITE, which we also logged: Contact: "Anonymous" <sip:Restricted@3.3.3.3:5060> The log message says: [R-MAIN:...] Re-INVITE received from 4.4.4.4:5060 to RURI sip:Restricted@3.3.3.3:5060;lr. Note a subtle detail here: the ';lr' parameter is present, which is an attribute of the Record-Route inserted by the sending ITSP (3.3.3.3). It's at the bottom of the Route set, of course, below Kamailio's two RRs (inserted for the ingress UDP interface and the egress TLS interface): Route: <sip:Restricted@3.3.3.3:5060;lr> This leads to two questions whose causes seem to be related: 1. Why does Kamailio think the request URI of this re-invite is something other than what $mb reveals it to be? 2. Is that, presumably, why it does not match 'myself'? 3. Why would Kamailio think it is actually set to the far-end Record-Route URI? This is version: kamailio 4.4.5 (x86_64/linux) d48094.

rtpproxy or rtpengine with Kamailio and Asterisk
by Wilkins, Steve 14 Aug '18

14 Aug '18

Good Morning everyone, Has anyone ever gotten rtpproxy/rtpengine to work with Kamailio and Asterisk? I have tried both, and even though I see no errors with either, and when I make calls I see rtpproxy/rtpengine traffic, I am still seeing media traffic go directly to and from Asterisk. I just can't get the media packets to not go directly from Asterisk to the Callee and visa-versa. Any ideas on where I am messing up in my kamalio.cfg file? Thank you!, -Steve

Can Kamailio interface with an asterisk server based on the fqdn of a call?
by Wilkins, Steve 14 Aug '18

14 Aug '18

Hi All, Is it possible for Kamailio to interface with a particular Asterisk Server based on the FQDN of a caller? I would like to pass calls received by Kamailio through to different Asterisk Servers based on the FQDN of the caller. I have used Load Balancing before, but I want to select which Asterisk Server the call is directed to. Thank you,

Rtpengine?
by Wilkins, Steve 14 Aug '18

14 Aug '18

HI All, I am not sure if I understand it correctly but I thought that I could use rtpengine to redirect media packets. My current SIP flow is => Softphone=>Kamailio=>Asterisk=>Kamailio=>Softphone, and Media flows from is Asterisk<=>softphone. But I don't want Media to flow this way. That is, I do not want Asterisk and the Softphone to be aware of each other. I would like the Media to go through Kamailio just like SIP packets do. I installed rtpengine and it starts and runs with no errors. I even see traffic with the call is made but media traffic still flows from softphone<=>asterisk. Any ideas? Thank you,

Re: [SR-Users] problem with compiling kamailio version 5.1.4 including a private Module
by Abdulaziz Alghosh 13 Aug '18

13 Aug '18

Hi Henning, thanks again. I found meanwhile the root cause. It caused as you said by the old logic of the make file. I used instead the new Formula of the tm module’s make file (as i remember). Consequently, it did not bring the compilation through those unwanted libraries. I will spot the details later when i am back in office next Monday. BR Abdulaziz On Thu 9.

app_lua and lua_run parameter count
by Asgaroth 13 Aug '18

13 Aug '18

Hi All, Quick question with regards the lua_run function in app_lua module. The documentation for v5.0.x states: "Execute the Lua function 'func' giving params as parameters. There can be up to 3 string parameters. The function must exist in the script loaded at startup via parameter 'load'. Parameters can be strings with pseudo-variables that are evaluated at runtime." Does this mean that lua_run can only have 3 parameters, or, does it mean that the function within the lua script can have up to 3 parameters? I have a function within lua that currently needs 3 parameters, so I'm hoping I can do the following: lua_run("some_function", "param_1", "param_2", "param_3") However, I'm not sure, from the documentation, if I can do this. On a side note, but related, can I pass defined variables/constants as parameters to lua_run too, for example, something like: #!define VAR_1 1234 #!define VAR_2 hello lua_run("some_function", "$rd", VAR_1, VAR_2) Some clarification would be greatly appreciated. Thanks for reading.

Lua KEMI crash
by Ivaylo Markov 13 Aug '18

13 Aug '18

Hello, I have Kamailio 5.1.4 (from deb.kamailio.org) running on a Debian 9 AMD64 VM with 1 CPU and 1G of RAM on ESXi. For KEMI I am using the liblua5.1-0:amd64 package, version 5.1.5-8.1+b2. The configuration is rather simple - dispatcher module reading the gateways from a file and forwarding everything to them based on a custom variable. There are 2 gateways in the file being pinged with OPTIONS packets every 10 seconds. Only a single SIP user is connecting to the machine (besides the occasional scanner). I can post the config if necessary, but I don't think that is the issue (see below). The crash has happened twice already - once on 2018-08-07 19:45 and 2018-08-08 14:33 EEST. You can find an excerpt from the Kamailio debug log at https://paste.fedoraproject.org/paste/bvyUMj3s5g2CcBN3JSBt5A/raw. As you can see, it crashes when trying to run the Lua route on an incoming packet. I am assuming the problem is this: Aug 8 14:33:14 lb-dev1 kamailio[13209]: *** Error in `/usr/sbin/kamailio': realloc(): invalid next size: 0x00005573dbff1ef0 *** However, I could not find any (direct) `realloc()` calls in the source for app_lua, so maybe this is an issue somehwere in liblua... Thoughts? Ivaylo

USRLOC db_mode=4 and server_id
by Darren Williams 13 Aug '18

13 Aug '18

I am currently using multiple instances of Kamailio with a common database and using the usrloc module with db_mode=4 and server_id to filter the contacts that get loaded at startup on each server. The problem I seem to have is that using the RPC call ul.add there I cannot see any parameter to send to specify the server_id. The server_id that the contact is given is 0. If I manually go into the db and modify the server_id everything works as expected. I think I must be missing something somehwere as I'mn sure you shouldn't need to do this. Can anyone help please. Thanks Daz

MYSQL and various
by Laura 12 Aug '18

12 Aug '18

Dear list, on my kamailio 4.4.7 i use interactions with MYSQL. For example .. i use it for some black list control and other like this.. sql_query("cb", "select id from blacklist where cli='$var(g2)' and (ippeer = '$si' or ippeer = 'ALL')", "rabl"); if($dbr(rabl=>rows)>0){ sql_result_free("rabl"); sl_send_reply("403","Forbidden blacklist"); exit; } sql_result_free("rabl"); I was wonder what was the best method to prevent the query going on if mysql don't respond for high load or other situation.. If Mysql is not able to reply to the query tight now the call continue over the configuration... what is the best way to prevent this and for examples drop it with a standard SIP 503 error. I have search on docs.. but i haven't found any valid way. Thanks Laura

Hello, We're here to ask you what's the ratio between cpu cores/ghz, ram and how many contemporary calls kamailio can manage before it maxes out its capabilities and crash.

UDP workers block when one or more rtpengine instances go offline
by Sebastian Damm 10 Aug '18

10 Aug '18

Hi, we run multiple rtpengine servers to share the load. Whenever we need to take an rtpengine server offline, we used to just block the control port via iptables, then no new calls ended up on this instance of rtpengine. This worked pretty well in Kamailio 4.4.5. However, since Kamailio 5.0, and the problem persists with 5.1.4, Kamailio hangs almost immediately after we block the control port traffic. In the log file there are almost no packets processed except every few seconds, which looks like a timeout thing. Did we configure anything wrong there? Or is the "dead rtpengine detection" just broken? Our configuration: loadmodule "rtpengine.so" modparam("rtpengine", "rtpengine_disable_tout", 120) modparam("rtpengine", "setid_avp", "$avp(rtpsetid)") modparam("rtpengine", "rtpengine_sock", "0 == udp:1.2.3.4:9001=2 udp:1.2.3.5:9001=2 udp:1.2.3.6:9001=2") modparam("rtpengine", "rtpengine_sock", "1 == udp:2.3.4.5:9001=2") Any help appreciated. Regards, Sebastian
