Acknowledgement procedure
If an emergency call is send to a normal phone and not to a call center you can do
this with or without adn acknowledgement procedure. If the acknowledgement
procedure is active the call is fully terminated only after receiving the digit
0
(call
end). That means that only afterwards the call sequence will be terminated. Without
an acknowledment procedure the call is terminated just hanging up the phone.
Further it is possible to force the emergency call termination only using a local pro-
cedure at the device after the liberation has been done (as required by the EN81.28
(2018) specifi cation). See also

.
PLEASE NOTE!
The Helpy GSM emergency phone works digital. That means that on the con-
trary to pure analogue solutions the emergency phone knows always when the
called party will answer and close the call. In this way it is possible to manage
an emergency call to more telephone numbers also with a deactivated acknow-
ledgement procedure. But an enabled acknowledgment procedure will ensure
that the call is not lost also if it will reach an answering machine or similar
devices. An operation conform to the EN81.28 specifi cation without an active
acknowledgement procedure is only possible if it ensured that the device
cann't reach any automatic answering machine.
As default the acknowledgement procedure is activated. To deactive it dial:
