A pre-emptive priority call (PPC) is either an Emergency
Group Call or a Private PPC (half-duplex or full-duplex call).
The feature allows to disconnect the on-going lower priority
call and to connect to the incoming higher priority call.
To place a PPC, see the Emergency Operation and Private
Call sections in the user guide.
The MTM800 Enhanced will receive the call via speaker or
Telephone Style Handset earpiece, according to the setting
used when the PPC is received.
Receiving a PPC is explained in the following paragraphs.
In the screens,
<Any> in Use
refers to any of the non-
emergency voice calls: Group, Private, Phone, or PABX.
Receiving an Emergency Group Call during a Call
The MTM800 Enhanced receives the Emergency Group Call,
drops the on-going non-emergency voice call, and connects
to the Emergency Group Call.
Receiving a Private PPC during a Call
If configured by your Service Provider, the MTM800
Enhanced receives the PPC, drops the on-going, non-
emergency, lower priority voice call, and connects to the
higher priority Private Call.
A PPC with lower or equal priority, will be dropped without
any indication to the called user and will enter the missed call
list.
For call alert, see settings in the Tones menu option
