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".
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.
This is the periodic time (in ms) that the UCM6100 will use to check on a
voltage drop in the line. The default setting is 200. The valid range is 50
to 3000.
Configure the ring timeout (in ms). Trunk (FXO) devices must have a
timeout to determine if there was a hangup before the line is answered.
This value can be used to configure how long it takes before the
UCM6100 considers a non-ringing line with hangup activity. The default
setting is 8000.
Configure the RX gain for the receiving channel of analog FXO port. The
valid range is from -13.5 (dB) to + 12.0 (dB). The default setting is 0.
Configure the TX gain for the transmitting channel of analog FXO port.
The valid range is from -13.5 (dB) to + 12.0 (dB). The default setting is 0.
Configure to enable CallerID detection. The default setting is "Yes".
Enable to detect Fax signal from the trunk during the call and send the
received Fax to the default Email address in Fax setting page under web
GUI->PBX->Internal Options->Fax/T.38.
Note:
If enabled, Fax Pass-through cannot be used.
Select the Caller ID scheme for this trunk. The default setting is
"Bellcore/Telcordia".
Configure the time interval between off-hook and first dialed digit for
outbound calls.
Enable automatic recording for the calls using this trunk. The default
setting is disabled. The recording files can be accessed under web GUI-
>CDR->Recording Files.
If selected, the trunk will be disabled.
Configure the maximum number of current calls over the trunk at the
same time. The default setting is 0, which mean no limit.
Busy Detection is used to detect far end hangup or for detecting busy
signal. The default setting is "Yes".
