Hi Bogdan Thanks you very much for the support. It solved the issue.
Can you suggest a proper tutorial for a better understanding of opensips 's working.

What you can do is to force the registration of only one contact, new contacts overwriting the existing ones. How to do that: save("location","c1f"); see: http://www.opensips.org/html/docs/modules/1.8.x/registrar.html#id292725 c1 - limit to only one contact per user f - overwrite existing one Regards, Bogdan-Andrei Iancu OpenSIPS Founder and Developer http://www.opensips-solutions.com On 06/20/2012 09:51 AM, Arjun Shankar K S wrote: Hi Bogdan, Thanks you very much for your response and time.

Also can you please clarify, 1. What does the q parameter in the SDP signify? 2. Why does the value of line param keep changing? Is it correct to have it like that?

If so, opensips will do parallel forking (for the received requests) to all registered contacts.
