[SR-Users] Kamailio+Asterisk integration :'481 dialog/transaction does not exists' error.

[Ravindra Gowda]

Dear All,

I have integrated Kamailio (Version  4.0.1) with Asterisk (Version 11.4.0
rc1) server. I should have get VoIP features(call, SMS) with this
integrated server.  But when i tried to call other end SIP client through
this integrated server, I'm getting this '*481 dialog/transaction does not
exists*' error (please find the attachment 'call.pcap' below).
SMS is through with the kamailio server without any problem (Find the
attachment 'SMS.pcap' below).
But when it comes to Calling feature, something is wrong and i am unable to
find it.
So please help me in resolving this issue.

My system configuration is as follows:
 Host Architecture: i686
 OS : Ubuntu 12.04 LTS
 Clients: Wi-Fi enabled VoIP phones.

Also find the attachments below for the kamailio configuration file and
tcpdump based trace files for Calling and SMSing process, to give a more
complete picture.

Any help will greatly appreciate.

*Thank you and Best regards,*
*R Ravindra **Gowda***
