Transfer to outside lines caller ID

[wackarnold]

When transferring to a outside line, for example a answering service. I am trying to make it so the caller ID is the actual number that called and not the caller ID that the server is sending out. I am using sip trunks also.

Make sure the carrier isn't overriding it. Also, check under Phone System->Outside Lines->Modify SIP proxy. See if "Use Caller ID Number from external sources" is checked.
