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.

Note

The following sessions show the enhancements of connected line identification

according to the connected line identification source configured on the IP phones.

1) The IP phone checks Privacy: id header preferentially, if there is a Privacy: id in the

18X or 200OK response, the connected line identification information will be hidden

2) If there is not any Privacy: id header in the 18X or 200OK response, the IP phone

checks and presents the connected line identification from the P-Asserted-Identity

header.

3) If there is not P-Asserted-Identity header in the I8X or 200OK response, the IP phone

If the callee already exists in the local directory, the local contact name assigned to the

callee should be preferentially displayed.
