Back to Basics - What is an ATA?

The interesting thing about VoIP is that the user can choose to place calls in multiple different ways: an IP Phone, a softphone and the one and only, an ATA.

So, what’s an ATA?

An ATA (Analog Telephone Adapter) is a device used to connect a standard analog telephone to a device in order to place calls over the Internet... and there are several types of ATAs! ATAs basically create a physical connection between a phone and a computer or a network device, some perform analog-to-digital conversion and connect directly to a VoIP server, while others use a software for either or both tasks.

When users are making and receiving a call using an ATA, they will get the ability to access different features of VoIP including CallerID name, call transfer and call waiting. Inside the ATA, there is a processor that helps to encode the voice and ensures that it is sent along correctly over the Internet. Additionally, ATA devices also have an Ethernet port (also referred as WAN) to connect the device to your modem or router as well as a telephone jack to connect your phone to it. In some ATAs, there can be more than one Ethernet port, in order to connect, for instance, your computer.

Voice and sound quality are an important aspect when it comes to VoIP calls. You can try and make use of the Quality of Service (QoS), as it would provide priority to VoIP traffic on your network and thus, avoiding any quality issue with your service.

There are several types of ATAs available on the market, however, all of them serve the same purpose: they help to create a connection between the phone and the VoIP provider.

In sum, ATA devices offer businesses a reliable solution for making calls over the Internet. If you are looking to start using VoIP, but want to keep on using your analog phones, this is the device that you need.
