When the call goes out from this analog trunk, it will use the port that is
not used last time. And it will always use the port in the order of port 1-
>2->10->16->1->2->10->16->1->2->10->16..., following the last port
being used.

Descend
When the call goes out from this analog trunk, it will always try to use
the last idle FXO port. The port order that the call will use to go out
would be port 16->port 10->port 2->port 1. Every time it will start with
port 16 (if it's idle).
The default setting is "Ascend" mode.
Busy Detection is used to detect far end hang up 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 hang up the channel. However, this might
lower the probability to get random hang up.
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)".
