1）General

·Trunk Name

A unique label used to identify this trunk when listed in outbound rules,

incoming rules, etc. Ex: 'Port 5'

·Audio Setting

Normally you should not have to adjust your analog ports beyond the initial

calibration. Should you still need to fine tune your audio settings, please make

adjustments as necessary.

2）Advanced Options

·Busy Detection

Busy Detection is used to detect far end hang-up or for detecting a busy signal.

Select “Yes” to turn this feature on.

·Busy Count

If Busy Detection is enabled, it is also possible to specify how many busy tones

to wait for before disconnecting. The default is 4, but better results can be

achieved if set to 6 or even 8. Remember, the higher the number, the more time

required to release a channel. A higher setting lowers the probability that you

will encounter random hang-ups

·Busy Pattern

If Busy Detection is enabled, it is also possible to specify the cadence of your

busy signal. In many countries, it is 500msec on, 500msec off. Without Busy

Pattern specified, MyPBX will accept any regular sound-silence pattern that

repeats <Busy Count> times as a busy signal. If you specify Busy Pattern, then

MyPBX will further check the length of the tone and silence, which will further

reduce the chance of a false positive disconnect.

·Caller ID Start

This option allows you to define the start of a Caller ID signal:

Ring: Start when a ring is received (Caller ID Signaling: Bell_USA, DTMF).

Polarity: Start when a polarity reversal is started (Caller ID Signaling:

V23_UK,V23_JP,DTMF).

Before Ring: Start before a ring is received (Caller ID Signaling: DTMF).

·Caller ID Signaling

This option defines the type of Caller ID signaling to use. It can be set to one of

the following:

Bell: bell202 as used in the United States

v23_UK: Used in the UK

v23_JP: Used in Japan

DTMF: Used in Denmark, Sweden, and Holland
