Analog Settings 
Call Waiting 
Configure to enable/disable call waiting feature. The default setting is 
"No". 
User ‘#’ as SEND 
If configured, the # key can be used as SNED key after dialing the 
number on the analog phone. The default setting is "Yes".

The valid range is -30dB to +6dB. The default setting is 0. 
MIN RX Flash 
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. 
MAX RX Flash 
Configure the maximum period of time (in milliseconds) that the 
hook-flash must remain unpressed for the PBX to consider the event as a

modified. The default setting is 1250ms. 
Enable Polarity Reversal 
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". 
Echo Cancellation 
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. 
3-Way Calling 
Configure to enable/disable 3-way calling feature on the user. The default 
setting is enabled.
