Wireless VoIP Adapters (ATA) | Linksys PAP2

Once you have made the decision to use Voice Over Internet Protocol, you may find it helpful to continue using your regular analog telephone. If so, it is necessary to purchase a VoIP adapter.

A VoIP adapter is also known as an ATA or Analog Terminal Adapter. The function of an ATA is to allow you to connect an analog phone to your IP telephony service.

Do your research before selecting an ATA. There are various types available, and some VoIP providers require you to use a specific adapter.

Your selection of an ATA also might depend on the features you require. Some consumers may look specifically for multiple ports, allowing them to hook up both a phone and a fax machine.

Others might have limited office space and look for the most compact Analog Terminal Adapter available with just a single port for attaching a phone.

For all consumers, sound quality is important. Regardless of the features you require, arm yourself with as much knowledge as possible.

Some terminology is important to know. Adaptors offer various ports. FXS ports are used for the connecting of your analog telephones.

All devices will have at least one FXS port, as that is the primary function of the adapter.

Ethernet ports are offered for Internet connection. An FXO port allows for a connection into a traditional phone line.

Some more expensive adapters provide the FXO port as a failover, in case a network, or Voice Over IP service is down.

The FXO port allows you to switch back and forth between making phone calls over a traditional phone line, and phone calls via the Internet.

An adapter with an FXO port is typically more expensive.

Various manufacturers are in the business of providing IP telephony devices.

Linksys offers a line of devices that are very popular among customers. Each Linksys VoIP adapter is recognized in the industry for its ease of use.

This factor alone accounts for much of the Linksys popularity.

Linksys PAP2 offers the basics, 2 FXS ports and an Ethernet port. Other models offer additional ports and features.

Wireless VoIP adapters are also available from a variety of manufacturers. These devices typically wrap multiple services in one device.

For example, the Linksys Wireless-G Broadband Router works as an Internet sharing router and offers phone jacks for use with your IP phone service.

With a wireless VoIP adapter such as this one, you can do research on the Internet, network with other computers in your office, and talk on your IP phone service at the same time.

The most important step is to speak to your Voice Over Internet Protocol provider. Once you know of any restrictions or requirements they have, you'll be able to research the adapters to find the one that is right for you.
