FXS-FXO Converters

If you want to create a VOIP to PSTN gateway and only have an
ATA with an FXS port, you can use an FXS-FXO converter connect the FXS port to a PSTN phone line.

Internet------ATA-----FXS-FX0 converter------PSTN phone line

This has been a popular option for creating a low cost PSTN gateway because of the lack of low cost ATAs with a FXO port. This option will probably continue to be popular even with the advent of the Sipura 3000 given the increasing numbers of VoIP service providers who provide users with their own nominated preconfigured brand of FXS gateway or ATA.

If you are using an FXS-FXO converter with a Sipura ATA then see this
mailing list posting.
