What’s the difference between DECT and Wi-Fi phones?

VoIP phones use your internet connection to make calls, as opposed to using a local telephone company and copper wires like traditional phones do.
As you know by now, some of them do it wirelessly. This means your phone can sit on your desk or be mounted to a wall with no cables running to and from it.
This is possible in one of two ways:

  • Digital Enhanced Cordless Telecommunications (DECT for short), which works like a local cellular network specifically designed to transmit voice
  • Wi-Fi, which uses your existing internet service and connection

With Wi-Fi, the phone simply connects to the internet and uses that connection to run your VoIP phone system.
DECT is a standalone system that includes a DECT base station and a wireless handset. In this case, you can think of the base station as the router used only for the phone. It doesn’t interfere with your Wi-Fi network, keeping it free for other communication channels.
Both options are common in wireless VoIP phones, and our list includes them. Let’s dive in!

How to choose the best wireless VoIP phone

Before you choose your final wireless VoIP phone, here are a few things to review:

  • Your budget
  • The most important call features and the option to add more
  • Your team size and its potential to grow
  • The range you want your cordless phones to cover
