DTMF Mode – There are four DTMF modes for you to choose.
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.
