Connected Line Identification Presentation (COLP) allows IP phones to display the
identity of the connected party specified for outgoing calls. IP phones can display the
Dialed Digits, or the identity in a SIP header (Remote-Party-ID or P-Asserted-Identity)
received, or the identity in the From header carried in the UPDATE message sent by the
callee as described in RFC 4916. Connected line identification presentation is also
known as Called line identification presentation. In some cases, the remote party will be
different from the called line identification presentation due to call diversion.
If the callee has existed in the local directory, the local contact name assigned to the
callee should be preferentially displayed.
