Unanswered Question
Jul 14th, 2010

Hi,

i've a 2811 voice-gateway in a location in poland.All inbound calls are fine - no problems. But i experiencing strange problems on outgoing calls: Some calls are OK - but almost all outgoing calls fail. In the debug, i get the "CALL_PROC" and the "ALERTING" (the called phone rings). But after that, my gateway sends a "DISCONNECT".

Are you using CM? I remember some wrong setting there can cause that. Unfortunately, I don't remember which ones.
