Setting DTMF signalling for VoIP

Setting DTMF signalling for VoIP
DTMF signalling is required, for example, for querying and controlling certain network
mailboxes via digit codes.
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.

The settings for DTMF signalling apply to all VoIP connections (VoIP accounts).

Defining recall key functions for VoIP (hook flash)

Your VoIP provider may support special performance features. To make use of these fea-
tures, your phone needs to send a specific signal (data packet) to the SIP server. You can
assign this "signal" to your phone's recall key.
If you press the recall key during a VoIP call the signal will be sent to the server.

Specify the local communication port that the phone should use to send and receive sig-
nalling data. Specify a number between 1024 and 49152. The default port number for
SIP signalling is 5060.
RTP port
Specify the local communication port that the phone should use to receive voice data.
Enter an even number between 1024 and 49152. The port number must not be the
same as the port number in the
est even number will be selected automatically (e.g. you enter 5003, then 5002 is set
automatically). The default port number for voice transmission is 5004.
