SIP to SIP connection

Billy

2005-06-23, 2:45 am

Hello All:

I am facing a weird problem using a cisco 7206 with IP2IP GW. I have
been able to place calls from H323 to SIP and vice versa, but I am not
being able to complete any calls from SIP 2 SIP. It sometimes rings on
the other side, but the call is dropped before answering the phone,
and the other times it rings, we answer the phone, and the call is
dropped to the caller side, and I got error Interworking.

I tried dozen of codec configurations, also codec transparent, but it
does not work at all.

Does any body has any idea what might be happening ?

Please.. see below my main config file and some debugs..

Many thanks.
