A200 FXO Settings for Australia

The following configuration settings are required to operate the Sangoma A200 FXO ports in a mode compliant with A-Tick requirements:

1. The FXO port gain values must be set by editing the file /etc/wanpipe1.conf (or whatever wanpipe file corresponds to the A200 card) and adding following settings:

RM_FXOTXGAIN=-55
RM_FXORXGAIN=-20

2. Asterisk software echo cancellation must be disabled. Ensure the file /etc/asterisk/zapata.conf contains the following lines:

echocancel=no
echocancelwhenbridged=no

3. The duration of hook flash generated by Asterisk must be set to a compliant value of 120ms. Ensure the file /etc/asterisk/zapata.conf contains the following lines:

rxflash=100

A10x Settings for Australia

The following settings may be useful when configuring the Sangoma drivers for use with Australian providers:

Media type	E1/T1	This will be E1 for all Telstra and Optus lines. Only select T1 (or any of the other options) if you know you are connecting to foreign equipment
Framing type	CRC4/NCRC4	Telstra and Optus use CRC4
Clock	Normal/Master	Normal means that clocking is provided by the remote end, which will be the case for most provisioned lines Master means that the Sangoma card provides the clocking itself. This should not be necessary in most cases - if it is, you should already know why!
Signalling type	PRI CPE/PRI NET	CPE stands for "Customer Premises Equipment" and is the setting that most Telstra and Optus lines will expect Only select NET if you know the remote device is in CPE mode.
