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 calls can be performed locally or on the server. When performing anonymous call on local, the 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.

The following table lists the parameters you can use to configure the anonymous call.
