Callback if busy
Many service providers offer the supplementary service of callback if busy (CCBS).
When the person whom you are calling is engaged in another conversation (you will
hear the busy tone), then you may activate this service.
The telephone network monitors now the line of the person you are trying to call.
When the other party becomes free, your own telephone starts ringing and when you
answer, the network automatically sets up the connection.
Activating callback if busy
You are trying to call someone. The called party is already engaged and you hear the
busy signal.
Open the menu by pressing the Menu key.
Select , press the Menu key.
Depending on the service provider you may hear a message.
Press the talk key to return to standby mode and wait for the network
to reconnect you.
Note • Ask your service provider about the availability and any charges of this service.
• This service will usually remain active for a limited period of time
(e. g. 30 minutes). Ask your service provider for details.
