Intro
Thinking about switching to VoIP (Voice over Internet Protocol)? One of the most common questions people ask is: “What equipment do I actually need to use VoIP at home?”
The answer is simpler than you might think. With the right internet connection and a few pieces of hardware, you can enjoy reliable, crystal-clear phone service at a fraction of the cost of a traditional landline.
In this guide, we’ll explain the difference between VoIP and landlines (PSTN), list the essential equipment you’ll need, and show you how NetJOI makes setup effortless with pre-configured adapters.
PSTN vs VoIP: The Quick Comparison
Feature | PSTN (Landline) | VoIP (Internet Phone) |
---|---|---|
Infrastructure | Copper wires, switches | Internet connection |
Cost | $50–$70+/month | $11.95–$16.95/month |
Features | Caller ID, voicemail (extra cost) | Caller ID, voicemail, forwarding (included) |
Portability | Tied to your home address | Works anywhere with internet |
Scalability | Expensive, needs new lines | Easy, just add devices or lines |
Reliability | Works during power outages | Requires internet + power |
PSTN has been around for over a century, but VoIP is the future. With today’s internet speeds, VoIP call quality is on par with, or better than, landlines, while delivering major cost savings and flexibility.
Essential Equipment for VoIP
To use VoIP at home, you’ll need:
- A Reliable Internet Connection
– At least 1 Mbps upload/download per call is recommended for stable voice quality.
– For households with multiple calls/devices, higher bandwidth is better. - VoIP-Compatible Device
- VoIP Phones: Special phones designed for VoIP (e.g., Ooma phones).
- Computers with Softphone Software: Apps that let you call through your laptop/desktop.
- Smartphones/Tablets with VoIP Apps: Services like Skype or apps from your provider.
- Traditional Phones with an ATA (Analog Telephone Adapter): The simplest way to use your current phone with VoIP.
- An ATA Adapter (if using your existing phone)
– Converts analog phone signals into digital signals for VoIP.
– Small, affordable, and easy to set up.
What’s an ATA Adapter and How Does It Work?
An Analog Telephone Adapter (ATA) bridges the gap between your traditional phone and the digital world of VoIP. It allows you to keep using your old handset while still getting the benefits of modern internet-based calling. The ATA Adapter converts traditional analog phone signals into digital signals that can be transmitted over the internet, allowing your old phone (landline) to make VoIP calls.

How it works:
- Converts analog signals → digital packets → sends them over your internet.
- Plugs into your router/modem and your existing home phone.
- Provides access to all VoIP features like voicemail, call forwarding, and caller ID.
Setting Up an ATA Adapter
Here are the generic steps to set up an ATA:
- Connect the ATA to your router
– Use an Ethernet cable to connect the ATA to an available port on your router. - Attach your phone
– Plug your analog phone into the port labeled “Phone” on the ATA. - Power it on
– Connect the ATA to a power outlet. After a short boot-up, the device configures itself automatically or via a web interface (depending on the model).
Once connected, your old phone is now VoIP-ready.
