A VoIP adapter, often called an analog telephone adapter or ATA, converts analog telephone signals into data that can travel over an IP network. It may let a compatible analog phone or device connect to a VoIP service through an Ethernet connection.
An adapter can be practical when a business wants to reuse a simple analog phone, but it is not always the best choice. Compatibility, power, network quality, fax behavior, emergency calling, and the advanced features your users need should all be reviewed before deployment.
