DTMF mode –
There are four selections provided here:
InBand:
Choose this one then the Vigor will send the
DTMF tone as audio directly when you press the keypad on
the phone.
OutBand:
Choose this one then the Vigor will capture the
keypad number you pressed and transform it to digital form
then send to the other side; the receiver will generate the
tone according to the digital form it receive. This function is
very useful when the network traffic congestion occurs and
it still can remain the accuracy of DTMF tone.

DTMF tone and transfer it into SIP form. Then it will be
sent to the remote end with SIP message.
