Gigaset S68H: Continuing a call on a Bluetooth headset
Precondition : Bluetooth is activated; a connection has been established
between the Bluetooth headset and the handset (
£
Page 140 ).
Press the talk key on the Bluetooth headset; it may take up to 5 seconds to
establish a connection to the handset.
For further details about your headset, see the user guide issued with it.
Dialling emergency numbers – defining dialling plans
You can use the Web configurator to block certain numbers or to define which
of your numbers (fixed line network, VoIP) should be used to call specific num-
bers (
Dialling Plans
,
£
Page 197 ).
If you enter a number that has a defined dialling plan, the call will be made
via the line defined in the dialling plan – regardless of whether the talk key is
pressed briefly or pressed and held. Any automatic area code will not be pre-
fixed to the number.
Emergency numbers
Dialling plans for emergency numbers (e.g. the local emergency service
number) are preset for certain countries. Emergency calls are then always
made via the fixed line network.
You cannot delete or deactivate these dialling plans. However, you can change
the connection through which each emergency number should be called (e.g.
if the phone is not connected to the fixed line network). You must make sure
that the VoIP provider for the selected connection supports emergency calls. If
the VoIP connection is deleted from the configuration, the emergency call can
no longer be made.
If your phone does not have default dialling plans for emergency calls, you
should define the rules yourself (
£
Page 197 ). Assign them to a connection
that you know supports emergency calls. Calls to emergency numbers are
always supported by fixed line networks.
Please note: If no rules are defined for emergency numbers and you have pro-
grammed an automatic local area code (
£
Page 196 ), the code will be pre-
fixed to emergency numbers as soon as they are dialled via a VoIP connection.
Please note
Emergency numbers cannot be dialled if the keypad lock is activated. Before
dialling, press and hold the hash key
#
, to release the keypad lock.
