Using a telephone to send keypad sequences to a telephony provider
You can use keypad sequences (character and number sequences, for example *50#) to activate and configure services offered by your telephony provider (for example network mailbox, call diversion) in the provider's exchange.
1 Configuring a telephone to use the keypad function
Keypad sequences are strings of characters and numbers that you can use to enable or disable functions. You can use keypad sequences immediately 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 configure the keypad function first:
- Configure the telephone so you can send keypad sequences (sequences of characters and numbers, such as *121#) and enter special characters such as * and # with it. On many telephones, you can configure this function in the menu "Operation at a PBX > Dialing options > 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 for which you want to set up the service via keypad sequence.
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 (pick up the handset).
- Hang up again.
Note:Many telephones have a character limit. 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, the sequence is immediately available if needed and the length of the sequence is not limited.
