Making special settings for VoIP telephony
Activating Call Forwarding for VoIP connections
The settings for Call Forwarding are on the web page:
¤
Settings Telephony
You can divert calls to your VoIP connections and to your Gigaset.net number.
You can divert calls to your VoIP connections to any external number (VoIP, fixed line network or
mobile number). Call Forwarding takes place via VoIP.
You can divert calls to your Gigaset.net number within the Gigaset.net, i.e. to another
Gigaset.net number.
For each of your VoIP connections (VoIP accounts), you can determine if and when calls to the
corresponding VoIP number should be diverted to a different VoIP phone number.
Setting DTMF signalling for VoIP
You can change the settings for DTMF signalling in the DTMF over VoIP connections area on the
web page:
¤
Settings Telephony
DTMF signalling is required, for example, for querying and controlling certain network
mailboxes via digit codes or for remote operation of a local answer machine.
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 an "SIP Info" message.
Ask your VoIP provider which type of DTMF transmission it supports.
You can configure your telephone in such a way that it attempts with each call to set the most
suitable DTMF signalling for the current codec (Automatic).
Or you can explicitly define the type of DTMF signalling:
u
Audio or RFC 2833 if DTMF signals are to be transmitted acoustically (in voice packets).
u
SIP Info if DTMF signals are to be transmitted as code.
Notes
u
The settings for DTMF signalling apply to all VoIP connections (VoIP accounts).
u
DTMF signals cannot be transmitted in the audio path (Audio) on broadband
connections (the G.722 codec is used).
Configuring call transfer via VoIP
You can change the settings for call transfer in the Call Transfer area on the web page:
¤
Settings Telephony
You can connect an external call to one of your VoIP connections with a second external
participant (depending on the provider). You do this by establishing an external consultation
call to the second participant and pressing the R key on the handset once the second participant
has answered. The call is transferred.
