I re-ran the debugs and did a wireshark capture at the Ricoh machine itself. The MGCP call ID is listed below.   Oct 10 13:25:01.942: ISDN Se0/0/0:23 Q931: TX -> SETUP pd = 8  callref = 0x2091     Thank you,   Eric

Attached are the logs.   The failing call is: Oct  9 18:41:15.110: ISDN Se0/0/0:23 Q931: TX -> SETUP pd = 8  callref = 0x1ECF   Please let me know if these lend any insight into why the outbound is failing.   Thank you,   Eric

Once I get the machine to re-register to Call Manager again I will test and gather the debugs.  Something I changed as a test broke the registration and I can not get it to come back yet.  I will post the debugs as soon as I can.
