Changing Call Type
By dialing from the idle screen the user is given the possibility
to change the Type of the Call.
Modifying the Type of Call
The infrastructure can modify the type of call you started.
For example, you might start a Simplex Private Call, and the
infrastructure could modify the call to a Group Call.
The terminal will alert you of the modification and will display
the following messages, depending on the type of call:
• Call Modified (to Duplex)
• Call Modified Use PTT (modified to Simplex)
Continue the modified call depending on the type of call.
• Simplex Private Call modified from direct setup to hook setup:
a ringing tone will alert of the change.
• Simplex Private Call modified from hook setup to direct setup:
there will be no indication of the change.
Receiving Calls
Your MTP850 automatically receives the incoming call.
Additionally, if Inactivity Revert Mode is enabled, the MTP850
returns automatically to the Home display, after that call
ends.
Inactivity Revert Mode will occur if configured by your Service
Provider.
Your MTP850 alerts you of an incoming call depending on
the setting you selected in the Vibrate menu option (see
page 126) and the Tones menu option (see page 132).
During message or contact editing, scrolling through the
menu and changing any configuration you will be alerted of
an incoming Group/Emergency/Broadcast Group Call if
configured by your Service Provider.
