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.
Always depose an available telephone number as target. Ensure that no voice mail or
other announcement picks up automatically.
When disconnecting the connection between the end device and the telephone system, it
can take up to 60 seconds for the call forwarding to work. Once the end device is
reconnected to the telephone system, it can take up to 60 seconds for it to register.
Call forwardings can alternatively be activated through * codes:
*10 Activation of the call forwarding profile
*11 + destination Permanent call forwarding to telephone number
**11 Cancel permanent call forwarding
*12 + destination If no answer after a specific time, delayed call forward
to telephone number
**12 Cancel delayed call forwarding
*13 + destination If busy, forward to telephone number
**13 Cancel call forwarding if busy
*14 + destination Call forwarding if unavailable
**14 Cancel call forwarding if unavailable

Registering multiple bases
When registering multiple bases, be sure to always do so separately. This makes it easier to register
the handsets to the base. That is, if you would like to register 24 handsets for example, you must
have 2 bases. First, take base 1 and 12 of the 24 handsets. First, register base 1, then the 12
handsets, one after the other, to the telephone system and the base as described above. Once you
have registered all 12 handsets, please turn off the first base and repeat these steps for the second
base. That is, now register base 2 and the remaining 12 handsets to the telephone system and the
base.
This prevents transmission interference or problems with assigning the handsets.
