sip refer transfer in cvp comprehensive

i tried the sip refer transfer using a rf before the device target label and sending the call to the voice gateway instead to the cucm. i am getting the dial-peer match on the gateway to the cucm but the call fails. when i turned on sip error debugs i noticed a error message as " Not SIP2SIP".

the same sip refer transfer when sent to the cucm from call server works fine. it fails only when sent to the gateway.

any help is appreciated.


Re: sip refer transfer in cvp comprehensive

In some scenarios, it is desirable for Unified CVP to transfer a call to a SIP destination and not have Unified ICM and Unified CVP retain any ability for further call control. Unified CVP can perform a SIP Refer transfer, which allows Unified CVP to remove itself from the call, thus freeing up licensed Unified CVP ports. The Ingress Voice Gateway port remains in use until the caller or the terminating equipment releases the call. SIP Refer transfers may be used in both Comprehensive and Call Director deployments.
