*Edited to remove MMC numbers*

Anybody have a programming check list for getting SIP Trunks to work properly? I got them to connect with the SIP provider's server (I get the 'Yes' in "SIP Server Available" field). I also get dial tone when accessing the SIP Trunks via 8501, but I cannot complete any calls properly. I placed the assigned phone number in the DID table as well. Incoming calls get an error message about circuits being busy, and outgoing calls come back into the phone system no matter what I dial. I've tried using the manual to get the incoming & outgoing VOIP digit mmc's set up, but as most of you probably know, those manuals are not always detailed enough.

Any help would be much appreciated.

System is OS7200 v. 4.42a
