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 local answer-
ing 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 a "SIP Info" message.
Ask your VoIP provider which type of DTMF transmission it supports.

Defining recall key functions for VoIP (hook flash)
Your VoIP provider may support special performance features. To make use of
these features, 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.
