FRITZ!Box 5490 Service - Knowledge Base
Selecting a different outgoing number when making a call
Telephones connected to the FRITZ!Box automatically use a certain number to make calls, depending on the setting. However, when you make a call, you can override this setting and select a different number to use for the call. The telephone's number settings and dialing rules are then suspended for this call.
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 telephone that is connected to the "FON S0" port or 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 Using a keypad sequence to select the outgoing number
- Click "Telephony" in the FRITZ!Box user interface.
- Click "Telephone Numbers" in the "Telephony" menu.
- Check which keypad sequence is given in the "Preselection" column for the telephone number you would like to use to make the call.
- Dial the keypad sequence before entering the number you would like to call.
To call the number 1234 using the second Internet telephone number, dial *122#1234.
