In addition, you can press the Advanced button to configure tone settings, volume gain,
MISC and DTMF mode. Advanced setting is provided for fitting the telecommunication
custom for the local area of the router installed. Wrong tone settings might cause
inconvenience for users. To set the sound pattern of the phone set, simply choose a proper
region to let the system find out the preset tone settings and caller ID type automatically. Or
you can adjust tone settings manually if you choose User Defined. TOn1, TOff1, TOn2 and
TOff2 mean the cadence of the tone pattern. TOn1 and TOn2 represent sound-on; TOff1 and
TOff2 represent the sound-off.
If your upstream speed is only 64Kbps, do not use G.711
codec. It is better for you to have at least 256Kbps upstream
if you would like to use G.711.
Single Codec – If the box is checked, only the selected
Codec will be applied.
Packet Size-The amount of data contained in a single
packet. The default value is 20 ms, which means the data
packet will contain 20 ms voice information.

voice on both sides is active or not. If not, the router will do
something to save the bandwidth for other using. Click On
to invoke this function; click off to close the function.

here.
