SIP trunk issue

Trying to get a Cisco Call manager to talk to Asterisk—

One way works— SIP clients can call extensions on the CCM-

CCM cannot call the Asterisk server:

This shows up in the Asterisk box (asterisk -r -vvvv)

acsasteriskCLI>
– Executing AbsoluteTimeout(“SIP/10.12.1.11-b7a00470”, “15”) in new stack
– Set Absolute Timeout to 15
– Executing Congestion(“SIP/10.12.1.11-b7a00470”, “”) in new stack
== Spawn extension (from-sip-external, 6351, 2) exited non-zero on ‘SIP/10.12.1.11-b7a00470’

I don’t know enough about debugging the Asterisk to know what this means about where my incoming SIP calls are going to…

help???
