Line Identification Presentation
Yealink 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 the phones to display the caller identity, derived from a SIP
header contained in the INVITE message when receiving an incoming call. Yealink phones can derive caller iden-
tity from three types of SIP header: From, P-Asserted-Identity (PAI) and Remote-Party-ID (RPID). Identity present-
ation is based on the identity in the relevant SIP header.
Connected Line Identification Presentation (COLP): It allows the phones to display the identity of the connected
party specified for outgoing calls. The 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 mes-
sage sent by the callee as described in
Called line identification presentation. In some cases, the remote party will be different from the called line iden-
tification 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 pref-
erentially displayed and stored in the call log.
