Handling Calls

The MBU 400 offers standard call handling features whether connected through a landline or a VoIP internet line. Intercom calls (between handsets on the same gateway) also have several call handling options.

You can place an active external call on hold if required. When a call is on hold, the “Call held” message displays at the top of the phone’s screen and the active call icon turns yellow as shown below. The caller on hold hears music playing until reconnected as an active call.
