Incoming Intercom Calls
The SIP-T48G IP phone supports to automatically answer an incoming intercom call by default.
The phone automatically plays a warning tone when it receives an incoming intercom call. In
addition, you can enable the phone to mute the microphone when it automatically answers an
incoming intercom call. You can also enable the phone to automatically answer an incoming
intercom call while there is already an active call on the phone. The active call is then placed on
hold.
