Firmware Version 1.0.0.1 UCM6200 Series IP PBX User Manual Page 148 of 320

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.

Tone Settings

Busy Detection

Busy Detection is used to detect far end hangup or for detecting busy

signal. The default setting is "Yes".

Busy Tone Count

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

Congestion detection is used to detect far end congestion signal. The

default setting is "Yes".

Congestion Count

If "Congestion Detection" is enabled, users can specify the number of

congestion tones to wait for. The default setting is 2.

Tone Country

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)".
