Configure to enable/disable call waiting feature. The default setting is "No".
If configured, the # key can be used as SNED key after dialing the number
on the analog phone. The default setting is "Yes".
Configure the RX gain for the receiving channel of analog FXS port. The
valid range is -30Db to +6Db. The default setting is 0.
Configure the TX gain for the transmitting channel of analog FXS port. The
valid range is -30Db to +6Db. The default setting is 0.
Configure the minimum period of time (in milliseconds) that the hook-flash
must remain unpressed for the PBX to consider the event as a valid flash
event. The valid range is 30ms to 1000ms. The default setting is 200ms.
Configure the maximum period of time (in milliseconds) that the hook-flash
must remain unpressed for the PBX to consider the event as a valid flash
event. The minimum period of time is 256ms and it can't be modified. The

If enabled, a polarity reversal will be marked as received when an outgoing
call is answered by the remote party. For some countries, a polarity
reversal is used for signaling the disconnection of a phone line and the call
will be considered as hang up on a polarity reversal. The default setting is
"Yes".

number of taps of cancellation.

When configuring the number of taps, the number 256 is not translated
into 256ms of echo cancellation. Instead, 256 taps mean 256/8 = 32 ms.
The default setting is "ON", which is 128 taps.

setting is enabled.
Configure the number of rings before sending CID. Default setting is 1.
