Re: CallManager 4.2(3) vs. Asterisk

For * -> CCM communications, can you get a packet capture
of what's 
happening?

For the CCM -> * communications, try resetting the trunk.
 Sounds like 
callmanager is refusing to believe the trunk is actually
there if you 
are getting fast busy immediately.  Dumb question, but you
do have the 
trunk pointing to the proper IP address of the * box,
right?

Also, I just did a quick tcpdump and it looks like
callmanager always 
replies with a 400 - Malformed/Missing URL when it gets sent
an OPTIONS 
request.
