[cisco-voip] Outbound calls failing 0x80D2 - Identified channel does not exist

[Kelemen Zoltan]

Quote from the troubleshooting big book :)

"Identified channel does not exist

This code indicates a call attempted on a channel that is not configured 
on the far end. This could happen if you are using a fractional PRI. As 
of CallManager version 3.3, CallManager does not support fractional PRIs."

quote ends. Well, the book is a bit old :)

Anyway, if you know that you should have  a full PRI, contact your 
telco. If not, there's a  service parameter in  CallManager, that can 
help you busy-out certain B channels, so those wouldn't be used. This is 
what I've found in a quick search: 
http://puck.nether.net/pipermail/cisco-voip/2005-July/006097.html

Incoming calls work because a) your teloc knows what they provide :) b) 
they are probably sending in the calls bottom-up anyway (starting from 
channel 1) I presume.

regards,
  Zoltan
