We are running Asterisk 10 and FreePBX 2.11. We have Polycom SoundPoint IP 450's and a VVX 400 phone. Whenever a call comes in from the outside and any of us transfer the call doing a blind transfer (both with the Polycom phone keys and using ## within the call), the transferred call shows as the internal extension caller ID name and number. When the user that the call was transferred to picks up the phone, they will then see the external caller ID information on their screen. I have tried changing the extension's "sendrpid" to "Send Remote-Party-ID header" and "Send-P-Asserted-Identity header" with the same results. Is there something I am missing?
