Can anyone explain how to do this?
My Callcentric provider has now allowed CallerID to be sent on SIP trunks. You have to just verify that your cell, or other line is yours before you can do it, which I did, and the instructions they send only say the following:
Send the Caller ID number of a DID on your account or an already verified number within the SIP INVITE message of an outbound call. To do so, have your IP PBX attach any of the following headers which are supported by most IP PBX's (check your vendor's documentation for support) to your outbound calls:
P-ASSERTED-IDENTITY
P-PREFERRED-IDENTITY
REMOTE-PARTY-ID
When we receive an outbound call from your IP PBX with any of the above headers, and that header includes a Caller ID number that is a DID on your account OR has been verified on your account we will pass that as the outbound caller ID for that call; over-riding any settings on your Callcentric account preferences.
