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 default setting is 1250ms.
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 hangup on a polarity reversal. The
default setting is "Yes".
Specify "ON", "OFF" or a value (the power of 2) from 32 to 1024 as the
number of taps of cancellation.
Note:
When configuring the number of taps, the number 256 is not translated
into 256ms of echo cancellation. Instead, 256 taps means 256/8 = 32 ms.
The default setting is "ON", which is 128 taps.
Configure to enable/disable 3-way calling feature on the user. The default
setting is enabled.
Configure the number of rings before sending CID. Default setting is 1.
