Receiving Calls
Your MTM5400 alerts you of an incoming call depending on
the setting you selected in the Tones menu option (see
page 101).
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.
Pre-emptive Calling
Pre-emptive calling is particularly useful when you need to
speak urgently with a user whose terminal is busy in a non-
emergency voice call.
A pre-emptive priority call (PPC) is either an Emergency
Group Call or a Private PPC (Simplex or Duplex call).
This 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.
Your MTM5400 receives 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.
For call alert, see settings in the Tones menu option (page 101).
