David,

  I'd hate to see you have to go that route (it carries its own
headaches).  You should try sticking with SIP.

  This is really more of a Cisco question.  Have you tried asking on

http://puck.nether.net/mailman/listinfo/cisco-nsp

-or-

http://puck.nether.net/mailman/listinfo/cisco-voip

  Even Voiceops may have some clues:

  Of course if you find the answer here it would be nice to have you
come back and let us know what you needed to do to CUCM to get it to
act sane...
