Fast Busy when sending calls over Intercluster Trunk to PSTN

Unanswered Question
Jun 19th, 2008

I have CCM6.1(2) setup in a lab w/ a Intercluster trunk connecting to our Production 4.2(3)environment. I can place calls back and forth between the two clusters over the ICT so the trunk is working, but I cannot place calls from the lab to PSTN via the ICT. I see the calls on the H323 gateway, but I get a fast busy on the phone. A debug on the H323 Gateway shows this:

Cause i = 0x80AC - Requested circuit/channel not available

Any ideas? Thanks.

I have this problem too.

You are sending 10 digits "2027115911" is this what you want? Is 10 digit dialing allowed in this area code? What happens when you send the call as 7 or 11 digits?

Yes. In the DC Area, you can send out 7, 10 & 11 Digits. I have dial-peers setup on the voice gateway for all 3. Sening out 7 digits gets the same result.
