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:
flash=100
preflash=100
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. | |
