Re: [SR-Users] Registration Failure - IMS

I have now spent some time to reproduce the issue. First of all: I had to adapt module reg_mod.c in ims_registrar_pcscf, because it containes a hardcoded P-CSCF address: str pcscf_uri = str_init("sip:pcscf.ims.smilecoms.com:4060"); which is only valid for smilecoms. Did you also change that? Then I got exactly the same problem. I found that the P-CSCF config causes in the part "# Check for Subsequent requests:" a reject " sl_send_reply("404","Not here");" I have doubts that this is correctly designed and have to dig deeper into the logic of the config-file. Fact is: the NOTIFY request does not contain a Route header and as it not an ACK it goes straight to the reject. Maybe any IMS expert can shed some light on this code as shown below: # Check for Subsequent requests: if (has_totag()) { # sequential request withing a dialog should # take the path determined by record-routing if (loose_route()) { if ($route_uri =~ "sip:mo@.*") { setflag(FLT_MO); } if(!isdsturiset()) { handle_ruri_alias(); } # RTP-Relay, if necessary route(RTPPROXY); t_relay(); } else { if ( is_method("ACK") ) { if ( t_check_trans() ) { # no loose-route, but stateful ACK; # must be an ACK after a 487 # or e.g. 404 from upstream server t_relay(); exit; } else { # ACK without matching transaction ... ignore and discard exit; } } sl_send_reply("404","Not here"); } exit; BR Franz

UDP send: Operation not permitted
by Sebastian Damm 11 Mar '16

Hi, we have a load balancer which is handling a lot of SIP traffic all day. There's always 20-40 Mbit SIP traffic going through. From time to time we see in our logs messages like these: Sep 16 09:46:28 ecker /usr/sbin/kamailio[25505]: ERROR: <core> [udp_server.c:591]: udp_send(): ERROR: udp_send: sendto(sock,0x7f2d9d6b3ce0,1321,0,46.237.225.126:5060,16): Operation not permitted(1) Sep 16 09:46:38 ecker /usr/sbin/kamailio[25194]: ERROR: <core> [udp_server.c:591]: udp_send(): ERROR: udp_send: sendto(sock,0x7efc982b8fc8,420,0,82.113.121.183:35794,16): Operation not permitted(1) Sep 16 09:46:40 ecker /usr/sbin/kamailio[25505]: ERROR: <core> [udp_server.c:591]: udp_send(): ERROR: udp_send: sendto(sock,0x7f2d9d6b3ce0,1338,0,5.158.137.9:55067,16): Operation not permitted(1) Sep 16 09:46:44 ecker /usr/sbin/kamailio[25183]: ERROR: <core> [udp_server.c:591]: udp_send(): ERROR: udp_send: sendto(sock,0x7efc982d9f48,450,0,178.165.131.197:37515,16): Operation not permitted(1) Sep 16 09:46:49 ecker /usr/sbin/kamailio[25643]: ERROR: <core> [udp_server.c:591]: udp_send(): ERROR: udp_send: sendto(sock,0x7f93fb624530,496,0,172.56.7.69:25643,16): Operation not permitted(1) Sep 16 09:46:55 ecker /usr/sbin/kamailio[25335]: ERROR: <core> [udp_server.c:591]: udp_send(): ERROR: udp_send: sendto(sock,0x7f41632cda98,598,0,80.215.234.139:3396,16): Operation not permitted(1) Sep 16 09:46:56 ecker /usr/sbin/kamailio[25345]: ERROR: <core> [udp_server.c:591]: udp_send(): ERROR: udp_send: sendto(sock,0x7f41632f4840,459,0,94.197.120.191:8225,16): Operation not permitted(1) I know that these messages can be produced by iptables blocking the outbound traffic. But our outbound chain looks basically like this: root@ecker:~# iptables-save | grep OUTPUT :OUTPUT DROP [0:0] -A OUTPUT -m state --state RELATED,ESTABLISHED -j ACCEPT -j ACCEPT -A OUTPUT -m state --state INVALID -j DROP -A OUTPUT -o lo -m state --state NEW -j ACCEPT -A OUTPUT -o lo -j ACCEPT -A OUTPUT -m state --state NEW -j ACCEPT We don't have the nf_ct_sip module loaded, syslog doesn't say anything, and even clearing all iptables rules doesn't eliminate those errors. Has anyone ever seen this? It looks like a load thing, because at weekends there are significantly less errors. Thanks, Sebastian

Development open again for master branch
by Daniel-Constantin Mierla 11 Mar '16

Hello, as branch 4.4 was created to host the upcoming release series 4.4, new features can be now pushed to master branch. They will be part of the next future release, likely to be numbered 5.0. Any fixes that affect existing code in branches 4.4 or older version have to be backported - push first to master and then cherry pick -- some guidelines exemplified with branch 3.2 are available at: - https://www.kamailio.org/wiki/devel/backporting-to-3.2.x As usual, the next future release will be out as stable version in like 8-10 months, with the additional note that 5.0 is planned to include some major refactoring and enhancements. See: - https://www.kamailio.org/wiki/devel/kamailio-5.0-design Many thanks to all contributors and enjoy Kamailio!

Hello, the GIT branch 4.4 was created, it will host the release series 4.4.x. To get this branch from GIT, you can use: git clone https://github.com/kamailio/kamailio.git kamailio cd kamailio git checkout -b 4.4 origin/4.4 Notes about installing Kamailio from this branch are available at: - https://www.kamailio.org/wiki/install/4.4.x/git Hopefully in about two weeks or so the full release of 4.4.0 will be out. >From now on, any corresponding fix has to be pushed first to master branch and then cherry-picked to branch 4.4. No new features can get in branch 4.4. Enhancements to documentation or helping tools are still allowed.

SIP Autentication Failed
by Bruno Henrique Gomes Gouvêa 11 Mar '16

11 Mar '16

Hello, First excuse any mistakes in English. I'm working on a platform that makes use of integrated Kamailio with asterisk (Elastix mt). This platform allows the login of my SIP clients via the extension number and the client's domain, where the kamailio after authentication change the username to sip EXTENSION + _ + DOMAIN (expected by Asterisk) and sends to the asterisk. I need the client can also send the sip user in standard EXTENSION + _ + DOMAIN, for it changed the view subscriber to also return a username record in the format that the softphone is sending, but the platform still seems not authenticate the REGISTER using new way functions in auth_check ("$ FD", "subscriber", "0") and auth_challenge ("$ FD", "0"). Thus works: Login: 101 Domain/server: pabx999999.ligou.me Password: PASSWORD_PLAIN This way does not work: Login: 101_pabx999999.ligou.me Domain/server: pabx999999.ligou.me Password: PASSWORD_PLAIN Already got a good look at the documentation and could not find the problem, could give me some help?
