[cisco-voip] SIP trunk CUCM 7

[Wes Sisk]

A list troll kindly clarified for me:
CM will do authentication on a SIP trunk if configured with the 
appropriate profile.  CM sends a message, receives a challange in 
response, and upon matching the realm will provide authentication.   
However CM will not send REGISTER message to register a SIP trunk.  Most 
providers require registration.

HTH,
Wes
