Hi sorry,

I forget to give my openser.cfg, there is one more point if i am using STUN server in our linksys device the call goes normal for long time till user finish the call. It seems something wrong in NAT configuration.

Subject: Calls disconnect automatically
Date: Sun, 20 Jan 2008 18:01:48 +0800

Hi Friends,

I start getting one problem, the calls disconnect automatically in 30 and 32 sec.
I am using openser + rtpproxy before with the same openser.cfg it was running smoothly and once traffic increased this problem appeared.

Could you please help me to solve this issue because i put openser in production and now no one can make long call.
