A customer can answer an incoming call without ending the first call and change lines talking to both callers in turn. To change lines, press a special key depending on your phone (refer to a user-guide). This way, several call lines can be supported.
If one caller puts the other on hold, the latter will hear a melody. You cannot turn it off.
The service is available to all A1 customers.
How to activate:
- via USSD *43# call key;
- in your phone menu.
To check if a call hold mode is active, make a request *43#call key.
To deactivate, send *43#call key.
