5. Express calls

Express calls are immediate one-way calls between two people. They are
connected without the recipient answering. You can make express calls to TETRA
network numbers.
During a WAP or data connection, an incoming express call may be changed to a
one-way phone call (network service); the radio alerts you and you need to press
to answer the call. (Receiving calls may be possible only when data transfer
is not in progress.) The WAP or data connection is suspended during the call, and
the radio will try to resume it after the call is ended.
Express calls are a network service. For details and availability, contact your
service provider.
