Kamailio SCTP with CentOS
by Mellow Yellow 13 Aug '15

13 Aug '15

Hey guys, I've been pulling out my hair for a few days trying to get SCTP with Kamailio working in CentOS 7... with no luck at all. When attempting to start Kamailio via the 'kamctl start' command I get the following error: INFO: Starting Kamailio : ERROR: PID file /var/run/kamailio.pid does not exist -- Kamailio start failed When attempting to start Kamailio via the 'systemctl start kamailio' command, I get the following: Job for kamailio.service failed. See 'systemctl status kamailio.service' and 'journalctl -xn' for details. When checking the 'systemctl status kamailio -l' command, I get the following: kamailio.service - SYSV: Kamailio is a fast, reliable and flexible SIP Server. Loaded: loaded (/etc/rc.d/init.d/kamailio) Active: failed (Result: exit-code) since Thu 2015-08-13 00:42:51 AEST; 14s ago Process: 19229 ExecStart=/etc/rc.d/init.d/kamailio start (code=exited, status=1/FAILURE) Aug 13 00:42:51 Elastix5.workgroup /usr/sbin/kamailio[19242]: INFO: rr [rr_mod.c:174]: mod_init(): outbound module not available Aug 13 00:42:51 Elastix5.workgroup /usr/sbin/kamailio[19242]: INFO: usrloc [hslot.c:51]: ul_init_locks(): locks array size 1024 Aug 13 00:42:51 Elastix5.workgroup /usr/sbin/kamailio[19242]: ERROR: ctl [init_socks.c:115]: init_unix_sock(): ERROR: init_unix_sock: bind: No such file or directory [2] Aug 13 00:42:51 Elastix5.workgroup /usr/sbin/kamailio[19242]: ERROR: ctl [ctl.c:273]: mod_init(): ERROR: ctl: mod_init: init ctrl. sockets failed Aug 13 00:42:51 Elastix5.workgroup /usr/sbin/kamailio[19242]: ERROR: <core> [sr_module.c:945]: init_mod(): Error while initializing module ctl (/usr/lib64/kamailio/modules/ctl.so) Aug 13 00:42:51 Elastix5.workgroup /usr/sbin/kamailio[19242]: INFO: <core> [sctp_core.c:53]: sctp_core_destroy(): SCTP API not initialized Aug 13 00:42:51 Elastix5.workgroup kamailio[19229]: Starting kamailio: Aug 13 00:42:51 Elastix5.workgroup systemd[1]: kamailio.service: control process exited, code=exited status=1 Aug 13 00:42:51 Elastix5.workgroup systemd[1]: Failed to start SYSV: Kamailio is a fast, reliable and flexible SIP Server.. Aug 13 00:42:51 Elastix5.workgroup systemd[1]: Unit kamailio.service entered failed state. So I started to think there was an issue with the SCTP config or whether SCTP was enabled in CentOS. However, everything looks fine: # cat /proc/modules sctp 217455 2 - Live 0xffffffffa03ed000 # /sbin/lsmod | grep sctp sctp 217455 2 libcrc32c 12644 2 xfs,sctp # more /proc/sys/net/sctp/addip_enable 1 # checksctp SCTP supported SCTP modules installed properly: Package lksctp-tools-devel-1.0.13-3.el7.x86_64 already installed and latest version Package lksctp-tools-doc-1.0.13-3.el7.x86_64 already installed and latest version Package lksctp-tools-1.0.13-3.el7.x86_64 already installed and latest version Running the ' sctp_test' command between two servers, SCTP is working fine... I can capture SCTP packets between the servers. I've left the Kamailio.cfg file as is... with the only modification being made to enable the SCTP module to start: enable_sctp = 1 Checking 'kamailio -v' USE_SCTP is enabled: # kamailio -v version: kamailio 4.3.1 (x86_64/linux) f38e67 flags: STATS: Off, USE_TCP, USE_TLS, USE_SCTP, TLS_HOOKS, USE_RAW_SOCKS, DISABLE_NAGLE, USE_MCAST, DNS_IP_HACK, SHM_MEM, SHM_MMAP, PKG_MALLOC, F_MALLOC, DBG_F_MALLOC, USE_FUTEX, FAST_LOCK-ADAPTIVE_WAIT, USE_DNS_CACHE, USE_DNS_FAILOVER, USE_NAPTR, USE_DST_BLACKLIST, HAVE_RESOLV_RES ADAPTIVE_WAIT_LOOPS=1024, MAX_RECV_BUFFER_SIZE 262144, MAX_LISTEN 16, MAX_URI_SIZE 1024, BUF_SIZE 65535, DEFAULT PKG_SIZE 8MB poll method support: poll, epoll_lt, epoll_et, sigio_rt, select. id: f38e67 compiled on 18:17:56 Jul 20 2015 with gcc 4.8.2 I've tried installing Kamailio with the precompiled rpms for CentOS 7, and I also followed some guides on installing in via GIT & compiling it myself... however the issue still remains. Any help would be greatly appreciated as I've completely run out of ideas, and there isn't much info on the web about Kamailio & SCTP. Thanks, Rob

XCap Server + Postgre
by Igor Olhovskiy 12 Aug '15

12 Aug '15

Hi! I'm experience really strange behavior of Kamailio. Right now it's using postgre database When trying to implement XCAP server capabilities, according to http://kamailio.org/docs/modules/4.3.x/modules/xcap_server.html#idp76784 on a block if (!www_authorize("xcap", "subscriber")) { www_challenge("xcap", "0"); exit; } While trying to test it via browser (user test, pass test) I've got these errors in log Aug 12 12:34:57 sip01 /usr/sbin/kamailio[7655]: WARNING: db_postgres [km_dbase.c:235]: db_postgres_submit_query(): postgres result check failed with code 7 (PGRES_FATAL_ERROR) Aug 12 12:34:57 sip01 /usr/sbin/kamailio[7655]: WARNING: db_postgres [km_dbase.c:239]: db_postgres_submit_query(): postgres query command failed, connection status 0, error [ERROR: relation "subscriber" does not exist#012LINE 1: select password from subscriber where extension='test' AND u...#012 ^#012] Aug 12 12:34:57 sip01 /usr/sbin/kamailio[7655]: WARNING: db_postgres [km_dbase.c:235]: db_postgres_submit_query(): postgres result check failed with code 7 (PGRES_FATAL_ERROR) Aug 12 12:34:57 sip01 /usr/sbin/kamailio[7655]: WARNING: db_postgres [km_dbase.c:239]: db_postgres_submit_query(): postgres query command failed, connection status 0, error [ERROR: relation "subscriber" does not exist#012LINE 1: select password from subscriber where extension='test' AND u...#012 ^#012] Aug 12 12:34:57 sip01 /usr/sbin/kamailio[7655]: WARNING: db_postgres [km_dbase.c:235]: db_postgres_submit_query(): postgres result check failed with code 7 (PGRES_FATAL_ERROR) Aug 12 12:34:57 sip01 /usr/sbin/kamailio[7655]: WARNING: db_postgres [km_dbase.c:239]: db_postgres_submit_query(): postgres query command failed, connection status 0, error [ERROR: relation "subscriber" does not exist#012LINE 1: select password from subscriber where extension='test' AND u...#012 ^#012] Aug 12 12:34:57 sip01 /usr/sbin/kamailio[7655]: ERROR: db_postgres [km_dbase.c:247]: db_postgres_submit_query(): 0x7f3fb0660b10 PQsendQuery Error: ERROR: relation "subscriber" does not exist#012LINE 1: select password from subscriber where extension='test' AND u...#012 ^#012 Query: select password from subscriber where extension='test' AND user_context='xcap' Aug 12 12:34:57 sip01 /usr/sbin/kamailio[7655]: ERROR: <core> [db_query.c:132]: db_do_query_internal(): error while submitting query Aug 12 12:34:57 sip01 /usr/sbin/kamailio[7655]: ERROR: auth_db [authorize.c:175]: get_ha1(): failed to query database Without this block, I don't get user auth.

kamailio as SIP Agent
by Sandeep Chakravarthi 12 Aug '15

12 Aug '15

Hi, We have a requirement with one of our telco We are using asterisk in our servers and we are planning to implement SIP-I protocol and we choosed kamailio for it. In Kamailio website, i came to know that kamailio will be supporting both SIP-I and SIP-T protocols Below is what we need and pls confirm whether it is possible or not? Asterisk PBX <-------> Kamailio <--------> Telco MSC Telco will be forwarding the calls to kamailio on sip-i protocol and kamailio server has to forward the calls to our Asterisk server by converting sip-i to standard sip protocol Similiarly Asterisk will be initiating sip call to kamailio server and kamailio server should convert it into SIP-I and should forward the call to Telco MSC 1. I am able to establish the SIP trunk [sending OPTIONS from asterisk and kamailio acknowledges with 200 OK] between Asterisk and Kamailio using dispatcher module in kamailio and sip.conf in asterisk. How to establish the SIP trunk between kamailio and telco MSC? [Generally MSC will act as SIP server and kamalio should send OPTIONS packet and MSC will acknowledges with 200 OK] My telco MSC has only provided me the MSC SIP IP and there were no username/passwords provided. Means i need to use IP based authentication for the SIP Trunk establishment. In Kamailio how to achieve it? Please help and any suggestions/feedback will be highly appreciated and thankful Regards, Sandeep

sdp manipulation in connection with rtpengine_offer/answer calls
by Juha Heinanen 12 Aug '15

12 Aug '15

it was not clear to me based on rtpengine module readme if rtpengine_offer/answer are same kind of sdp manipulation functions as, for example, sdpops module functions, i.e., will rtpengine functions pass to rtpengine the sdp as it is after possible earlier sdpops function calls and will possible sdpops functions calls after rtpengine function call keep on manipulating the sdp returned from rtpengine function call. -- juha

RTPProxy incorrect port 0 in reply from rtp proxy
by Grant Bagdasarian 12 Aug '15

12 Aug '15

Hello, I've been load testing kamailio(4.2) with rtpproxy(2.0) using sipp, and when I hit 50+ CPS I start getting the following error: "incorrect port 0 in reply from rtp proxy". I'm running 4 instances of rtpproxy on the same instance as kamailio. Could somebody tell me why I'm receiving this error? Do I need to run more instances of rtpproxy? # <#----------RTPPROXY Parameters----------#> modparam("rtpproxy", "rtpproxy_sock", "udp:127.0.0.1:7721 udp:127.0.0.1:7722 udp:127.0.0.1:7723 udp:127.0.0.1:7724") In request_route: if (is_method("INVITE")) { record_route(); if (has_body("application/sdp")) { rtpproxy_manage(); } } In onreply_route: if (has_body("application/sdp")) { rtpproxy_manage(); } rtpproxy -s udp:127.0.0.1:7721 -u rtpproxy rtpproxy -p /var/run/rtpproxy/rtpproxy.pid -l 10.0.0.1 rtpproxy -s udp:127.0.0.1:7722 -u rtpproxy rtpproxy -p /var/run/rtpproxy/rtpproxy1.pid -l 10.0.0.1 rtpproxy -s udp:127.0.0.1:7723 -u rtpproxy rtpproxy -p /var/run/rtpproxy/rtpproxy2.pid -l 10.0.0.1 rtpproxy -s udp:127.0.0.1:7724 -u rtpproxy rtpproxy -p /var/run/rtpproxy/rtpproxy3.pid -l 10.0.0.1 Regards, Grant

Re: [SR-Users] LCR Routing - Cost based routing
by DanB 12 Aug '15

12 Aug '15

Hi Alexandru, Well the concept is simple: on INVITE, you will issue a special format evapi request. You will receive the list of suppliers in the reply (which is received in a separate route) and you continue processing from there. These suppliers are simple tags so your creativity will be the limit of what you can do with them - eg: direct ip addresses received or tags of suppliers which you can further translate with drouting module or any alias related one. For more information on LCR please find this year's presentation on Kamailio World (which I strongly recommend to be attended): https://www.youtube.com/watch?v=Hsvcwleb-fY You can also find the kamailio configuration which I have used in the worshop here: https://github.com/cgrates/cgrates/tree/master/data/tutorials/kamevapi/kama… Let me know if further questions (or join our irc or mailing list so we do not create too much noise here).

Help with sip balancer
by Bruno 11 Aug '15

11 Aug '15

Hello, i'm on my first try with kamailio. I need to build a SIP balancer that should keep SIP registration from VoIP provider and route the calls to the asterisk boxes where an IVR will take care to answer. Here's my network topology: +---> [asterisk1] [public_ip] | 10.50.10.131 [router] <---NAT---> [kamailio] <---+ 10.50.10.1 10.50.10.120 | +---> [asterisk2] 10.50.10.132 In my setup i planned to use UAC and DISPATCHER modules. I started from the "kamailio-basic.cfg" and added some extra lines to handle UAC and DISPATCHER. All is working fine when i do a test call from a softphone inside network 10.50.10.0/24. When a call is coming from the sip carrier, troubles occurs because asterisk boxes are sending their internal ip in SDP. I understand that i need to rewrite SDP in that case, but i actually don't know how/where. I've attached kamailio configuration and a sip trace taken with sngrep where the problem is visible. For security reasons, i would like to force the RTP through RTPProxy. I'm missing something, and need your help me to understand my errors. Best Regards, Bruno

Trailing newline with {re.subst,expression}
by Daniel Tryba 11 Aug '15

11 Aug '15

I'm unable to get rid of the \n in "multiline" content of a var. xlog("var: $var(sdp)"); $var(sdp)=$(var(sdp){re.subst,/^a=rtcp:.*//}); xlog("var: $var(sdp)"); a=sendrecv#015#012a=rtcp:31543#015#012a=X-foo:bar becomes: a=sendrecv#015#012#012a=X-foo:bar Using the s flag results in no substitution at all, /^a=rtcp:.*//s should result in a=sendrecv#015#012 according to http://www.kamailio.org/wiki/cookbooks/4.3.x/transformations#resubst_expres… Is this a bug or a feature? If it is a feature, how to get rid of the newline (without additional regexps substitutions).

force_send_socket/$fs behaviour when binding to INADDR_ANY
by Alex Balashov 11 Aug '15

11 Aug '15

Hello, When binding Kamailio to 0.0.0.0, Kamailio no longer recognises any specific IP address homed on the system as being a "socket" for purposes of forcing traffic out of any specific interface (i.e. setting $fs), or any other purpose for which ingress and egress "sockets" are tracked (e.g. double RR). As I understand it, this is because Kamailio considers only addresses explicitly specified via the 'listen' core config directive to be valid "send socket" arguments. Kamailio _will_ accept addresses already attached to the interface if it is bound interface-wise, e.g. listen=eth1:5060 but not when addresses are added to the interface without restarting the proxy: # ip addr add dev eth1 172.30.110.10/24 Aug 10 17:31:35 centosity6 /usr/local/sbin/kamailio[28627]: WARNING: pv [pv_core.c:2285]: pv_set_force_sock(): no socket found to match [udp:172.30.110.10:5060] Is there any straightforward way to modify this behaviour, so that it would be possible to dynamically add addresses to existing physical interfaces and get Kamailio to utilise them as if they were bound at boot time?
