Hi Saurabh!

Your problem description is not detailed enough. If a client changes IP 
addresses, at first Kamailio can not even notice (as RTP sind 
peer-to-peer). Only if one of the clients sends requests, Kamailio may 
notice the IP address change. Thus:

- what activity is performed by the clients on IP address change? 
(reINVITE, REGISTER, BYE ....)

- If Kamailio crashes, it will usually report why/where it crashes. 
Configure your system to write core dumps as described here:
http://www.kamailio.org/dokuwiki/doku.php/troubleshooting:corefiles

Then send the backtrace of the coredump to the mailing list.

- Most times crashes are triggered by processing an incoming message. 
Please post the message which caused the crash (if so).

regards
Klaus
