Express calls (network service) are immediate one-way calls
between two people. They are connected without the recipient
answering. You can make express calls to TETRA network and
public telephone network numbers.
If you receive an express call when you are not using the
loudspeaker, your radio alerts you, and the call is connected only
after you have answered it by pressing .
An ongoing individual call may be disconnected automatically due to
a higher priority group call if your organisation has pre-configured
the radio to allow that.
