What is a VoIP Gateway?

Voice-over-Internet-Protocol is a packet-based technology for transmitting digitized voice over an Ethernet/IP network.
A VoIP gateway is a networking device that converts a traditional (legacy) phone signal (analog or digital) into a (digitized) packet-based, Internet Protocol (IP) communication stream. 

What is an ATA?

An analog telephone adapter (ATA) is a device for connecting traditional analog telephone system or a voice over IP telephony network.
An ATA is often built into a small enclosure with an internal or external power adapter, an Ethernet port, and one or more foreign exchange station (FXS) telephone ports. Such devices may also have a foreign exchange office (FXO) interface for providing alternative access to traditional land line telephone service.
