Disable This Trunk
If selected, the trunk will be disabled and incoming/Outgoing calls via this
trunk will not be possible.
DAHDI Out Line Selection
This is to implement analog trunk outbound line selection strategy. Three
options are available:

Ascend : When the call goes out from this analog trunk, it will always
try to use the first idle FXO port. The port order that the call will use to
go out would be port 1

port 2

port 10

port 16. Every time it will start
with port 1 (if it is idle).

Poll : 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 is idle).
The default setting is “Ascend” mode.
Echo Cancellation Mode
The Non-Linear Processing (NLP) in echo cancellation helps to
remove/suppress residual echo components that could not be removed by
the LEC (Line Echo Canceller). Following modes are supported:

Default: Slightly reduces the amount of detected background noise.

High Noise Level Adjustment: Greatly reduces the amount of
detected background noise.

Noise Masking : Injects noise to mask echo and greatly reduces the
amount of detected background noise.

White Noise Injection: Injects variable amounts of white noise based
on detected background noise and greatly reduces the amount of
detected background noise.
Direct Callback
Allows external numbers the option to get directed to the extension that last
called them.
For Example: User 2002 has dialed external number 061234575 but they
were not reachable, once they have received missed call notification on
their phone, they would mostly call back the number, if the option “Direct
Callback” is enabled then they will be directly bridged to user 2002
regardless of the configured inbound destination.
Tone Settings
Busy Detection Busy Detection is used to detect far end hang up or for detecting busy
