Codec (Priority 1-3):
Decide and make the codec priority with the supported

Detection) function for silence suppression. When VAD
is ON, the CNG (Comfort Noise Generation) function
will also be activated.

The VoIP phone supports three kinds of method to
generate DTMF tones such as Out Band (i.e. RFC
2833), In Band and SIP INFO.

When Out Band is selected, please also decide and enter the value of Payload Type in the blank. Please contact
