Problem routing to voicemail
by Christophe ROY 15 Nov '12

15 Nov '12

Hi everyone I'm trying to integrate Asterisk with Kamailio for voicemail. I tried to follow this tutorial: http://kb.asipto.com/asterisk:realtime:kamailio-3.3.x-asterisk-10.7.0-astdb BUT: - I had to adapt it because I use LDAP authentication with Kamailio - I had problems with Asterisk 10.7 (problems with chan_sip module crashing) so I've installed Asterisk 11 on another VM - we have high-availability with 2 Kamailio servers, with Kamailio listening on TCP (constraint from our SSL gateway in front of Kamailio) on a "virtual IP" (created by keep-alive): this VIP is not visible with ifconfig, but you can see it with the command "ip addr sh eth0" For now, we use Linphone on Windows as SIP clients to test. If I don't define WITH_ASTERISK, calls work, I can call someone(a)domain.tld However, if I define WITH_ASTERISK, calls fail (even with destination registered and available) and I have these errors in the logfile: Nov 15 11:45:08 kamailio1 /usr/sbin/kamailio[25308]: ERROR: tm [ut.h:333]: no corresponding socket for af 2 Nov 15 11:45:08 kamailio1 /usr/sbin/kamailio[25308]: ERROR: tm [t_fwd.c:424]: ERROR: can't fwd to af 2, proto 1 (no corresponding listening socket) Nov 15 11:45:08 kamailio1 /usr/sbin/kamailio[25308]: ERROR: tm [t_fwd.c:1530]: ERROR: t_forward_nonack: failure to add branches Nov 15 11:45:08 kamailio1 /usr/sbin/kamailio[25308]: INFO: <script>: reply error Nov 15 11:45:08 kamailio1 /usr/sbin/kamailio[25308]: ERROR: sl [sl_funcs.c:371]: ERROR: sl_reply_error used: I'm terribly sorry, server error occurred (1/SL) It seems to happen on the if (!t_relay()) line in ROUTE[RELAY] 192.168.14.25 is the real IP of the Kamailio server, 192.168.14.24 is the VIP of the Kamailio "cluster" 192.168.14.28 is the IP of the Mysql server 192.168.14.32 is the IP of the Asterisk server I can't find why the relay doesn't work. I've tried to bypass the VIP and have Kamailio listen on the real IP, but it still doesn't work: I don't seem to have the same errors as above, but I don't see any traffic between Kamailio and Asterisk. My kamailio.cfg is available here as it's too big for the list: http://pastebin.com/zhncJ6j1 What could be the problem? Thank you very much for your help Christophe

Replicate dialog state
by Kristofer Signer 15 Nov '12

15 Nov '12

In my current setup I've register messages replicated to a second server. Is it possible to also replicate other messages so I can hold dialog state on both servers? I've tried to read the documentation and also google but can't find any examples. Thanks ./Kristofer

RPC, XMLRPC or other
by Kristofer Signer 14 Nov '12

14 Nov '12

Hello, I'm trying to dig in to the kamailio XMLRPC interfaces and the limitations I read in http://www.kamailio.org/docs/modules/stable/modules/xmlrpc.html#xmlrpc.impl… is really a no go for us. For example, when to retrieve user locations and list of dialogs we get a xml document which is not so well formatted and we can not successfully parse it in an xmlrpc-parser. Is there other options for xmlrpc module? thanks ./Kristofer

Re: [SR-Users] sr-users Digest, Vol 90, Issue 39
by Yufei Tao 14 Nov '12

What I did to overcome this problem was writing a bash script, that checks if mysql is running, if so, start Kamailio, if not, start mysql first, then start Kamailio, and retries if things fail. And in /etc/rc.local, call this script. Seems to work fine on Ubuntu 10.04. Not tried 12.04 yet.

I have done some "reading" and found that Ubuntu has changed to upstart http://upstart.ubuntu.com/cookbook/. However, I could not find how I can start a non "upstart" style init script like Kamailio has before the upstart styled ones... I guess that I have to either to get the Kamailio community to create an upstart script or find some help from the Ubuntu community how to overcome the problem. Anyway, I think the Kamailio team should address it as it will become a problem for everyone using Kamailio on Ubuntu. Any help?

by Uri Shacked 14 Nov '12

14 Nov '12

Hi, When i set a timer to "request time out" kamilio generates a 408 with now to_tag. I saved the to_tag from the 183 and try to update the acc table with the to_tag (i need that for my CDR to work) My question is (understanding there is no option to set the to_tag on the 408) is: How to i get the right timing to update using sqlops? i must update after the acc inserted the row to the acc table.... Any ideas? Thanks, Uri

Presence Dialog Info synchronisation issue
by David 12 Nov '12

12 Nov '12

Hello, I have two Kamailio boxes running. First one routes calls between my phones and asterisk. Here are the extra lines compared to the default config that came with my installation on the first server. Let's call this server kamailio : loadmodule "pua.so" loadmodule "pua_mi.so" loadmodule "pua_dialoginfo.so" modparam("pua_dialoginfo", "include_localremote", 0) modparam("pua_dialoginfo", "include_tags", 0) modparam("pua_dialoginfo", "include_callid", 0) modparam("pua_dialoginfo", "caller_confirmed", 1) modparam("pua", "outbound_proxy", "sip:kamailio_presence_ip:5060") if ( is_method("SUBSCRIBE") ) { t_relay("kamailio-presence-ip", "5060"); } The second one handles presence stuff ( SUBSCRIBE and PUBLISH ), let's call it presence : After the standard sanity checks : if(is_method("PUBLISH")) { handle_publish(); t_release(); } else if( is_method("SUBSCRIBE")) { handle_subscribe(); t_release(); }; exit; The problem is that I have two phones connected to the same username on the server. Here is the sequence of events of a correctly functionning call : 1. Kamailio receives an INVITE 2. It sends the INVITE to each of the two phones 3. The first phone replies 180 Ringing 4. Kamailio sends a PUBLISH to presence 5. Presence replies with an OK, which includes a SIP-ETag header 6. Kamailio recieves the OK 7. Kamailio receives the 180 Ringing from the second phone 8. Kamailio sends a new PUBLISH with the SIP-If-Match using the value from the SIP-ETag header 9. Presence receives it, updates the presence table and sends an OK. This is ok, the trouble is when the second 180 Ringing reaches Kamailio before the OK to the publish with the SIP-ETag. 1. Kamailio receives an INVITE 2. It sends the INVITE to each of the two phones 3. The first phone replies 180 Ringing 4. Kamailio sends a PUBLISH to presence 5. Kamailio receives the 180 Ringing from the second phone 6. Kamailio sends a PUBLISH to presence 7. Presence replies with an OK, which includes a SIP-ETag header 8. Presence replies with an OK, which includes a second SIP-ETag header 9. Kamailio recieves the OK 10. Kamailio recieves the OK The presence table now has two seperate dialogs for the call because Kamailio didn't send the SIP-If-Match header as it did not yet receive the reply from presence. When the two phones start ringing at the same time, the time between the two packets arriving at the server is shorter than a round trip to the presence server. In the second scenario, Kamailio never updates the presence information using the first SIP-ETag, so the light on my phone stays stuck at "ringing". Where do I go from here ? Thanks, David

Returning problem
by Moacir Ferreira 12 Nov '12

12 Nov '12

My kamailio start script has the following BEGIN INIT INFO: # ### BEGIN INIT INFO # Provides: kamailio # Required-Start: $syslog $network $local_fs $time mysql # Required-Stop: $syslog $network $local_fs mysql # Default-Start: 2 3 4 5 # Default-Stop: 0 1 6 # Should-Start: postgresql mysql radius # Should-Stop: postgresql mysql radius # Short-Description: Start the Kamailio SIP proxy server # Description: Start the Kamailio SIP proxy server ### END INIT INFO However, when I boot my server Kamailio will start before mysql. So, after boot I can start Kamalio but at boot time it will fail. Any hints how to fix it? I am running Ubuntu server 12.04 LTS - 64 bits. All the code has been compiled at the server. Cheers!

LUA 5.2 - Support
by David | StyleFlare 12 Nov '12

12 Nov '12

Curious to know if there is any plans to support LUA 5.2. Seems like this is a newer release, I tried to build kamailio lua modules using 5.2 but it was not supported. Seems like some minor changes in the way LUA handles some things. Any ideas? Thanks.
