Using a telephone to send keypad sequences to a telephony provider

You can use keypad sequences (combinations of characters and numbers, for example *50#) to activate and configure services offered by your telephony provider (for example voice mailbox, call diversion) in the provider's exchange.

1 Configuring a telephone to use the keypad function

The following steps are only necessary if the cordless telephone is not registered to the FRITZ!Box's base station:

Note: If you are using a telephone that is registered to the base station of your FRITZ!Box (for example FRITZ!Fon C5), you do not have to configure it to use the keypad function.

Configure the devices so that you can dial special characters (such as * and #) or send keypad sequences (sequences of symbols and digits, such as *121#) with them.
Note: Many Gigaset telephones can be configured as follows: Select "Operation at a PBX" from the telephone's menu, then select "Dialing options" and enable the option "Dial * and #".

2 Sending a keypad sequence

Enter *#[keypad sequence] (for example *#*50#) on your telephone.
Press the call key (lift the receiver).
Hang up again.
Important: If you wish to use a keypad sequence to configure a service for a specific telephone number, then the telephone must be able to make calls using that number.
