10.7 Anonymous Call
Anonymous call allows the caller to conceal the identity information shown to callee. The callee’s phone LCD
screen prompts an incoming call from anonymity (there is no name, number or other information displayed).
Anonymous calls can be performed locally or on the server. When performing an anonymous call on local,
the IP phone sends an INVITE request message with a call source “From: Anonymous
<sip:anonymous@anonymous.invalid>;tag=878106cc5e”. If performing an anonymous call on a specific
server, you may need to configure the anonymous call on code and off code to activate and deactivate the
function of anonymous call on the server side.
The following table lists the parameters to configure an anonymous call.
Note: X means account ID and it can be number 1~8 for M3/M5/M7, and 1-20 for M8.
