When this one particular site dials out, they get the friendly lady saying 'You call cannot me completed as dialed'. They end call, press redial, and the call goes through. They are using 7941's. Our setup is CCM 4.1, Gateway is 2801 12.4(24), E1 card to an ISDN PRI.
On a debug isdn q931, I cannot see the first call, but I can see the succeeding one. Seems like CCM is getting confused about something? Have reloaded CCM and the router at site. Other sites with similar and the same set up are fine.
ANy ideas would be greatly appreciated, thanks,
Check the route list/ route group that you are using.Make sure that there isn't any other gateways in there that you could be sending out.Also check the distribution algorithm , might be that you are using circular and its sending calls to a non functioning gateway.
