Impossible to established a call

Unanswered Question
Dec 18th, 2008

Hi,

I'm with a CUCM 6.0 and a GW that I'm using to go through a private VoIP network (called RIG network). The GW is registered on a central GK in H323 and my GW is configured on the CUCM as a H323 gateway.

From my IP phones (behind the CUCM), I'm calling a telephone on the RIG network the remote phone is ringing but the call is impossible to start and after 10 seconds the call stop ????

Please find my GW debug in attached file.

Do not hesitate bto ask more specification about the architecture.

thanks

Olivier

You may also need to increase the "Media Exchange Timer" timer and "Media Exchange Interface Capability Timer".

Media Exchange Timer is the timer for two way audio media path establishment including cap exchange, MSD exchange and logical channel establishment. If two-way audio path is not established when Media Exchange Timer pops, the call will be terminated.
