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 telephone is connected to the "FON S0" port or you are using a cordless telephone that is not registered with the FRITZ!Box's base station:
Note:If you are using a telephone that is registered with 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. The telephone must be configured to make calls using the telephone number you are using keypad sequences to configuring the service for.
To send the keypad sequence *50#, enter *#*50# on your telephone. To send this sequence using the second Internet telephone number, enter *122*#*50# on the telephone.
- Press the call key (lift the receiver).
- Hang up again.
Note:Many telephones limit the amount of characters that can be entered. For example, FRITZ!Fon allows you to enter a maximum of 22 characters. If you save the keypad sequence in the FRITZ!Box telephone book, you can use the sequence right away and the sequence length is not limited.
