Description (partial)

A race condition is observed While doing a call-transfer, if PhoneA is in one node and PhoneB and PhoneC are in different node the transfer fails and CUCM cores in node where PhoneA resides.

PhoneA which is initiating the call should be in one node and the PhoneB which is doing the transfer and the target PhoneC for transfer should be in different node where PhoneB is trying another transfer to different phone.

Core was generated by `/usr/local/cm/bin/ccm'.
Program terminated with signal 11, Segmentation fault.
