Signaling Channels
A SIP signaling channel communicates between the system and the IP phone to perform call control, including
call setup, tear down, registration, and phone feature access.
The signaling channel implementation consists of the following elements:
•
SIP Virtual Board
– Establishes a logical board ID relationship with other types of physical boards in the
system (displayed on Board View window as SIPSP board).
•
SIP Signaling Channel
– Creates SIP signaling channels for IP Extensions (access through SIPSP
board, Channel Group configuration).
