Connected line identification presentation (COLP) allows IP phones to display the
identity of the callee specified for outgoing calls. The IP phone 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.
If the callee has existed in the directory, the local name assigned to the callee should be
preferentially displayed.
