Hi All, I am attempting to figure out the solution to the problem where a multi-pressence UA can have multiple incoming calls with the same Call-ID (along with To and From). This situation can arise when a call is forwarded between accounts and happens to arrive at the UA via different accounts/routes.

says--- page 12 Call-ID contains a globally unique identifier for this call, generated by the combination of a random string and the softphone's host name or IP address. The combination of the To tag, From tag, and Call-ID completely defines a peer-to-peer SIP relationship between Alice and Bob and is referred to as a dialog.
