Seen something very similar to this! I have to admit that this was for MGCP configuration and we saw this issue only for international and mobile numbers.
It seems (in CCM v3.1) that timer T302 is really the one expiring but we will need to see the earlier debug messages to confirm that - your debug extract looks correct!
Our findings were that if CCM does not get a response from the carrier (in the form of an INFO frame or another type for that matter) within the T302 timer for this number CCM initiates the DISCONNECT. We developed a work around to force these long distance and mobile numbers to use enbloc signalling so that a sending complete was sent with the call setup. This told the carrier that the dialling digits were complete and route the call. You'll need a route pattern something like "9.0!", or more for greater control.
Also, when testing make sure that you do your dialling off-hook, otherwise you will not see the real sequence and timing of events!
The short answer is that you don't.... That isn't entirely true while at
the same time it kind of is, but for the most part you don't configure
the softkeys. You enable or disable them via TCL. Here is the long
answer. Be sure to read the whole thing or e...
