CVP Warm Transfer With Queuing Get Disconnected

Problem Summary	CVP warm transfer with queuing gets disconnected after a few seconds when the transfer is complete. CUCM logs and/or sniffer trace show a reinvitation collision scenario. This only occurs with IP originated callers, not TDM callers.
Error Message	Logs show reinvitation collision.
Possible Cause	This problem is visible when CVP and CUPS are using proxy and UDP on the outgoing direction, and the CUCM SIP trunk is using TCP on the outgoing direction.
Recommended Action	Set UDP on the CUCM SIP trunk security profile or set CVP and CUPS to use TCP.
Release	Release 7.0(2)
Associated CDETS #	None.
