When adding an analog board (A200) to the board list, you are prompted to
tell the number of FXO interfaces and the number of FXS intefaces. If you
only have one type of interface, you have nothing to worry about.
If you have a mix of FXO and FXS interfaces on your board, you must know
that after the Quick Setup, the FXO interfaces will be given the first
wanpipe interface IDs and the FXS interfaces the last. For example, if you
have a board with 2 FXO and 2 FXS, the wanpipe interface IDs in the
pstn-config.xml file will be 0 and 1 for the FXO, 2 and 3 for the FXS.
If you have put the FXO module on your card in SLOT A and the FXS module
in SLOT B, the default configuration will match you board's configuration
(see A200
installation guide for slots position on the board).
If you have inverted this order for the modules on you board, simply go
to the "Configuration/PSTN Config" tab in the WebUI after the Quick Setup.
Find you board in the Boards section of the tree view and manually change
the Wanpipe Interface number of each interface: 0 and 1 for FXO becomes 2
and 3, 2 and 3 for FXS becomes 0 and 1 respectively.
