Small business VoIP phone system setup tutorial

So, assuming your phone network is compatible with the US POTS (Plain old telephone service) system, here's what you need. Analog interfaces for phones run in two modes: FXO or FXS. An FSX adapter, is a device that you connect a phone device to. It generates dial tone. That's not what you need.

What you need is an FXO device (sometimes called a channel bank). That is a device that emulates a phone device, and which consumes dial tone. Many devices sold as FXO gateways are expensive. If you have a real server, you can get an FXO PCI card from Digium for some hundreds of dollars, but that's expensive too.

Some cheap FXS devices can also operate in FXO mode. The cheapest one appears to be the Grandtream HT813 for $89: https://www.voipsupply.com/grandtream-ht813-gateway-ata

Thank you so much! I've already gotten started installing Asterisk and playing around. This has been most helpful!
