Compatible VoIP ATA devices

For connecting analog telephone networks and connecting analog telephone sets to Ozeki Phone System, an ATA device is required. An ATA device converts analog signals to digital and sends it over the internet. Every ATA device gets an IP address which is needed to communicate with Ozeki Phone System.

An ATA always has an ethernet connection to connect to the LAN, so it functions as a router. It also has FXO, FXS ports. The FXO connects the ATA to the PSTN, which is the analog phone network. The FXS connects the ATA to an analog phone or a fax machine (Figure 1). Some ATA devices has no FXO ports. So if you want to connect to the PSTN, be careful what you buy.

To help you choose the best device that fits you, we will show you a few:
