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.
