[cisco-voip] ISDN No voice..

[Bryan Deaver]

The timer expiry is because the GW does not send back a progress or alert
after the call_proc.  As to why, since you are using DID, you need to look
at the h323 side to see what is going on; debug h225 q931 to start would be
good.

What is the terminating h323 device?  If a cisco, what is the
configuration/version you are running?  Are you trying to setup this
h323/h225 call across some type of firewall?
