FAQs About VoIP Phone Systems

Can you use a normal phone with VoIP?

Yes, you can use VoIP technology with your existing phone. However, the usage will be slightly different than with a VoIP phone. To make your existing phone work with a VoIP system, you need an ATA or analog telephone adapter, which channels analog voice data into packets of information.

What is needed for a VoIP phone system?

That depends on which VoIP method you choose. You definitely need a broadband connection, preferably a fiberoptic one that’s more reliable. The best VoIP experiences are achieved with a full FTTP or Ethernet connection.

  • For VoIP with an adapter, you need the adapter, a compatible phone, and in some cases, a compatible router.
  • For VoIP with a smartphone, you need the phone, the installed app, and a Wi-Fi connection.
  • For VoIP with a computer, you need a desktop or laptop computer with an internet connection. You also need headsets or a good speaker, a microphone, and the right software.

No matter which method you use, the quality of your VoIP connection depends on your broadband connection.

How does a VoIP phone system work?

Unlike traditional phone systems that are physically connected to a telephone line, VoIP phone systems work over the internet. When using a VoIP phone:

  • You speak into the phone.
  • Analogous voice signals are converted to digital ones.
  • The digital signals are transmitted over your internet connection as data packets.

As long as you have a high-speed internet connection, router, and modem, you’re ready to use VoIP.

Does VoIP work if the internet is down?

Since VoIP calls are made over the internet, if your internet connection goes down, you lose the ability to make and receive calls. Businesses that install VoIP systems can prepare for such an event by:

  • Choosing a system with built-in redundancy and call continuity.
  • Using a backup or alternate ISP (internet service provider).
  • Establishing a backup connection between their private phone network and internet cable.
