Call Forwarding to activate VoIP connections

You can forward calls to your VoIP numbers and to your Gigaset.net number.
You can forward calls to your VoIP numbers to any external number (VoIP, fixed line net-

work or mobile network number). The forwarding is done via a VoIP connection.
You can forward calls to your Gigaset.net number within the Gigaset.net, i.e. to another

Gigaset.net number.
You can define if and when calls to your Gigaset.net number and some of your VoIP num-

bers (VoIP account) should be forwarded to this VoIP number.
You can also use the handset to define call forwarding and activate/deactivate it, see

page 46.

Setting DTMF signalling for VoIP

DTMF signalling is required, for example, for querying and controlling certain network

mailboxes via digit codes or for remote operation of the integrated answer machine

(Gigaset C475 IP).
To send DTMF signals via VoIP you must first define how key codes should be converted

into and sent as DTMF signals: as audible information via the speech channel or as "SIP Info"

message.
Ask your VoIP provider which type of DTMF transmission it supports.
