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
Keypad sequences are strings of characters and digits that can be used to enable or disable functions. You can use keypad sequences right away with telephones, such as FRITZ!Fon C5, that are registered with the base station of your FRITZ!Box. If you are using a cordless telephone that is not registered with the FRITZ!Box's base station, you must first set up the keypad function:
- Configure the devices so that you can send keypad sequences (sequences of symbols and digits, such as *121#) and dial special characters such as * and # with them. With many telephones, you can use the menu "Operation at a PBX > Dialing options > Dial * and #" to configure this.
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.
