Dear all,

My partner company are using an AudioCodes PBX system. But now they are 
expanding their branch, they want to set up FreeSWITCH PBX in new 
branch. The requirement is the new FS PBX server can communicate all 
extension of  the current AudioCodes PBX system via internal SIP trunk.

I have set up the sip trunk, the result is that two system can call 
together.
But If I make call from FS's extension to AudioCodes's extension, the 
call is connected and we can talk together, but it will be auto 
disconect after 10 seconds from AudioCodes side.  The phone status at FS 
side is still connected

Otherwise If I make call from AudioCodes's extension to FS's extension, 
It run well, no time limit.

I have checked the console log, it show that the call is still connected 
at FreeSWICH side, only AudioCodes side is disconnected.

If any one understand the problem please help me.

Thanks you very much!
Em Nguyen
