Advanced Options
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 "No".
Polarity on Answer Delay
When FXO port answers the call, FXS may send a Polarity Reversal. If
this interval is shorter than the value of "Polarity on Answer Delay", the
Polarity Reversal will be ignored. Otherwise, the FXO will onhook to
disconnect the call. The default setting is 600ms.
Current Disconnect Threshold
(ms)
This is the periodic time (in ms) that the UCM6510 will use to check on a
voltage drop in the line. The default setting is 200. The valid range is 50
to 3000.
