Analog Telephone Adapters
An analog telephone adapter acts as a hardware interface between an analog PSTN telephone system and a digital VoIP line. You don’t need an ATA if you are using PC-to-PC VoIP, but you will use it if you sign up for a monthly VoIP service to be deployed at home or in your office, and if you intend to use your existing phones.
Telephone Sets
The phone set is essential for VoIP — it’s both an input and an output device. Several types of phones can be used with VoIP, depending on the circumstances, your needs, and your choice. Although you can use an analog telephone designed for PSTN networks, you might find more value in a dedicated VoIP phone or even a non-hardware softphone app.
PC Handsets
Handsets resemble telephones, but they connect to your computer through USB or a sound card. They work together with a softphone allowing you to use VoIP more comfortably. They can also be plugged into an IP phone to allow many users to use the same phone. These devices are rarer than they used to be; most people now either use a PC headset or an ATA with a desk phone to communicate using VoIP.
PC Headsets
A PC headset is a standard multimedia device that allows you to hear audio from your computer and input your voice by using a microphone. Check out our list of the best USB headsets and the best Bluetooth headsets to help you pick the right device for you.
