FRITZ!Box 7330 – Service

Conducting internal calls

If several telephones are connected to your FRITZ!Box, you can conduct internal calls (that are free of charge) between them. For example, you can use a cordless telephone to call a telephone connected to an analog extension of the FRITZ!Box.

Note:The configuration procedure and notes on functions given in this guide refer to the latest FRITZ!OS for your FRITZ!Box.

1 Conducting internal calls

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.

Making internal calls

  • If you want all of the telephones connected to the FRITZ!Box to ring, dial **9 to initiate a broadcast call. You then conduct the call with the party who picks up the telephone first.
    • If a specific telephone should ring, dial ** and the internal telephone number of the telephone.

      Example:
      Dial **1 to call a telephone connected to the extension "FON 1".

      Note:You can find the internal numbers of the telephony devices in the FRITZ!Box user interface under "Telephone Book > Internal Numbers".
