Description (partial)

Symptom:
If the UAC gateway never sends an ACK message to CVP, CPV sends a REFER request to play back error message instead of sending a BYE.  Survivability tcl is not used either since it is a 3rd party gateway.

Conditions:
Gateway has a bug where it fails to send ACK.  CVP does not handle this error condition ideally.
