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.
Placing a Call on Hold
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.
To place a call on hold do the following.
1. During an active call, press the Hold softkey.
2. Press the Back softkey or the red key to return to the call.
Calling with a Call on Hold
You can make a call while a second call is on hold. When a call is on hold and you
connect to a second call the active call icon is yellow and blue as shown below (or
yellow only for intercom calls). The caller on hold hears music playing until
reconnected as an active call.
To make a call while leaving a call on hold do the following.
1. Place the active call on hold if you haven’t already done so (press the Hold
softkey).
2. Enter a number or use the Options softkey to find an Intercom, Contact, or Call
Log number.
3. Press the green key to complete the call.
