Line Identification Presentation
Line Identification Presentation
Yealink IP phones can derive calling and connected line identification from SIP headers and display the name asso-
ciated with the telephone number on the LCD screen.
Calling Line Identification Presentation (CLIP): It allows IP phones to display the caller identity, derived from a SIP
header contained in the INVITE message when receiving an incoming call. Yealink IP phones can derive 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.
Connected Line Identification Presentation (COLP): It allows IP phones to display the identity of the connected party
specified for outgoing calls. The IP phones can display the Dialed Digits, or the identity in a SIP header (Remote-Party-
ID, P-Asserted-Identity or contact) received, or the identity in the From header carried in the UPDATE message sent by
the callee as described in
. Connected line identification presentation is also known as Called line iden-
tification presentation. In some cases, the remote party will be different from the called line identification presentation
due to call diversion.
Note
If the caller/callee already exists in the local directory, the local contact name assigned to the caller will be preferentially dis-
played and stored in the call log.
