Anonymous Call
Anonymous call allows the caller to conceal the identity information shown to the callee. The callee’s
phone LCD screen prompts an incoming call from anonymity.
Anonymous call can be performed locally or on the server. When performing anonymous call on local,
the IP phone sends an INVITE request with a call source ” From: "Anonymous"
sip:anonymous@anonymous.invalid ”. If performing Anonymous call on a specific server, you may need to
configure anonymous call on code and off code to activate and deactivate server-side anonymous call
feature.
