Calling Line Identification Presentation (CLIP) allows IP phones to display the caller

identity, derived from a SIP header contained in the INVITE message when receiving an

incoming call. IP phones support deriving caller identity from three types of SIP header:

From, P-Asserted-Identity (PAI) and Remote-Party-ID (RPID). Identity presentation is

based on the identity in the relevant SIP header.

Note

The following sessions show the enhancements of calling line identification presentation

according to the calling 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

INVITE request, the calling line identification information will be hidden and the IP

phone LCD screen presents anonymous.

2) If there is not any Privacy: id header in the INVITE request, the IP phone checks and

presents the caller identification from the P-Preferred-Identity header.

3) If there is not P-Preferred-Identity header in the INVITE request, the IP phone

presents the caller identification derived from the FROM header.

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

INVITE request, the caller identification information will be hidden and the IP phone

LCD screen presents anonymous.

2) If there is not any Privacy: id header in the INVITE request, the IP phone checks and

presents the caller identification from the P-Preferred-Identity header.

3) If there is not P-Preferred-Identity header in the INVITE request, the IP phone checks

and presents the caller identification from the P-Asserted-Identity header.

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

caller should be preferentially displayed and stored in the call log.
