The FXO-2 module allows you to connect an additional two analog PSTN telephone lines to your existing Sangoma A200 or A400 with at least one module slot free.

You can install a maximum of two FXO-2 or FXS-2 modules in each A200 Remora card, and up to six in each A400 Remora card. If you have filled your existing module slots, you should add an additional Remora card to your order as well.

If you need assistance with expanding or upgrading your existing Sangoma A200 or A400 system, please contact us — we're more than happy to help!
