[SR-Users] Problem routing to voicemail

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 at 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.
What could be the problem? Thanks for your help
Christophe
Below is my kamailio.cfg:
