Calling Line Identification Presentation (CLIP)
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.
Caller ID source = FROM
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 touch
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.
Caller ID source = PAI
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 touch screen
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.
