Selecting a different outgoing call number when making a call

Depending on how they are configured, telephones connected to the FRITZ!Box automatically use a particular number to make calls. However, you can override this setting when you make a call and select a different number to use for the call. The telephone number settings and dialing rules are then suspended for this call.

Note:All instructions on configuration and settings given in this guide refer to the latest FRITZ!OS for the FRITZ!Box.

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 enable the keypad function first:

  1. 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 Using key commands to select a different outgoing call number

  1. Click "Telephony" in the FRITZ!Box user interface.
  2. Click "Telephone Numbers" in the "Telephony" menu.
  3. Check which key command is shown in the "Preselection" column for the telephone number you want to use for the call.
  4. Enter the key command followed by the number you want to call.

    To call the number 1234 using the second internet telephone number, enter *122#1234.
