Substitute Connection

You can enable the use of a backup connection. With this function the FRITZ!Box can automatically remedy the following disruption: An outgoing call cannot be established because the telephone number used is not registered. The reason for this could be a disruption with the telephony provider's equipment.

If the use of a backup connection is not enabled, the FRITZ!Box attempts to connect the call using a different telephone number.

Requirements

When a call cannot be established, the FRITZ!Box can use a backup connection whenever the following prerequisites are met:

• At least two telephone numbers are configured in the FRITZ!Box.
• You do not use Click to Dial to make calls.
