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".
Busy Detection is used to detect far end hangup or for detecting busy
signal. The default setting is "Yes".
If "Busy Detection" is enabled, users can specify the number of busy
tones to be played before hanging up. The default setting is 2. Better
results might be achieved if set to 4, 6 or even 8. Please note that the
higher the number is, the more time is needed to hangup the channel.
However, this might lower the probability to get random hangup.
Congestion detection is used to detect far end congestion signal. The
default setting is "Yes".
If "Congestion Detection" is enabled, users can specify the number of
congestion tones to wait for. The default setting is 2.
Select the country for tone settings. If "Custom" is selected, users could
manually configure the values for Busy Tone and Congestion Tone. The
default setting is "United States of America (USA)".
