Thanks Olle, it helped a lot Now, calls come through Asterisk and voicemail is working.... but it's "working too well" ;)
When I try to call someone, Asterisk tells me that the subscriber is absent and I'm sent directly to voicemail:
app_dial.c:2433 dial_exec_full: Unable to create channel of type 'SIP' (cause 20 - Subscriber absent)
if I take a look in the asterisk CLI, I have that:
rtpproxy1*CLI> sip show peers Name/username Host Dyn Forcerport ACL Port Status Description Realtime kamailio (Unspecified) a A 0 Unmonitored siptest2/siptest2 (Unspecified) D 0 Unmonitored Cached RT testteopad2/testteopad2 (Unspecified) D 0 Unmonitored Cached RT 3 sip peers [Monitored: 0 online, 0 offline Unmonitored: 0 online, 3 offline]
rtpproxy1*CLI> sip show registry Host dnsmgr Username Refresh State Reg.Time 0 SIP registrations.
And I'm not sure I understand correctly the line "Be sure you configure Asterisk to not authenticate SIP requests coming from Kamailio." in the tutorial: I've tried to add in sip.conf these lines:
[kamailio] type=friend permit=192.168.14.0/24 secret= transport=tcp outboundproxy=192.168.14.25
(Kamailio is 192.168.14.25)
Thanks for your help

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@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)
Seems like Kamailio and ASterisk is not using the same transports. Check sip.conf in Asterisk so that you enable the proper transports that you are using for forwarding. If Asterisk is ONLY listening to udp, add ";transport=udp" to the forwarding URI. To force TCP, use "transport=tcp".
Now since the error message indicates proto 1, which in Kamailio-speak is UDP, it seems like you have an issue with that.
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.
What could be the problem? Thanks for your help
If you forward register to Asterisk, you have to configure outboundproxy in sip.conf in asterisk so that you get messages back from Asterisk. Or use one of my branchces with support for the SIP Path header in Asterisk (using the PATH module in Kamailio).
Using the onsend route you can check IP, port and transport used to deliver a message from Kamailio. CHeck the Kamailio cookbook on the wiki for more information about that.
