Call Waiting
Call waiting enables you to receive another call when there is already an active call on your phone. If it is disabled,
the new incoming call will be rejected automatically.
You can enable call waiting feature and set the phone to play a warning tone to avoid missing important calls dur-
ing a call.
Yealink phones also support call waiting on code and off code to activate and deactivate server-side call waiting
feature. They may vary on different servers.
