You can activate or deactivate call forwardings via the telephone menu call settings.

You can select between the following call forwarding options:

Permanent call forwarding (always)

All incoming calls will be forwarded directly to the predefined telephone number.

Forward if busy (busy)

New calls will be forwarded immediately, when coming in during an active call. This call forwarding option functions only, if the Call Waiting function is deactivated.

Delayed call forwarding (no answer)

Call forwarding condition: You do not answer the incoming call within a defined time period (timeout).
The timeout can be set to 5, 10, 15 or 20 seconds.
Where should the incoming call be forwarded after the specified time has elapsed?
The caller receives a call waiting signal and is then forwarded to the defined destination.

If unavailable (not registered)

This option functions only if the end device is not registered to the telephone system:

• If the Internet connection fails or there is no LAN connection.

or

• If Call forwarding …if unavailable is programmed for a direct extension (e.g. extension 123 - John Doe) and a caller calls the direct dial number for the extension, call forwarding applies. If the extension is a member of a queue or a group and the queue or group receives a call, call forwarding for the individual extension no longer applies. In general, the destination should always be an available destination number. I.e., make sure that no voicemail or announcement comes on.
