Call forwarding of incoming mobile calls
Call forwarding is a mobile network service which allows incoming calls to be routed in the network to
an alternative number (such as a voicemail box) when certain criteria are met.
The terminal allows you to configure the operation of the call forwarding service by dialling codes
from the connected telephone. The various forwarding criteria are not mutually exclusive and can be
used in combination to divert different types of call to separate numbers.
Call forwarding dial codes:

Activate and register
Cancel &
deregister

Notes:
1. The numbers and call forwarding status are registered (stored) in the mobile network.
2. If in doubt about forwarding services provided, check with your network provider.
3. To specify a country code in a number, use the IDD prefix before the number. For example,
0044 specifies the UK.
“00” is the default IDD prefix and is configured with IPREFIX, see
page 16.
