Have you ever seen “VOIP Caller” on your phone and wondered what it meant? With the advancement of VoIP technology, businesses are finding it easier to connect with people via VoIP phone services. In this article, we will discuss what VoIP caller is and what you should know.

What is a VoIP Caller?

If your phone says “VOIP Caller,” it means someone is calling you using VoIP. VoIP stands for Voice over Internet Protocol. It is a cloud-based service that helps businesses make phone calls over the internet. All VoIP calls route through an internet connection instead of traditional wires and cables.

What is a VoIP System?

A VoIP system is a technology that allows you to make calls over a broadband internet connection. It converts your voice into a digital signal that is sent over the internet through a router. This signal is converted into a regular phone signal before it gets to the recipient.

A VoIP system comprises:

  • An internet connection: The most essential part of VoIP 
  • An adapter: Adapters convert the phone signals into digital signals. They are integrated into VoIP-based phones.
  • An audio pickup and a speaker: These are integrated into all phones. If you’re using a personal computer, you may need headphones with an in-built microphone.
  • Apps: You’ll need an app to run the VoIP system on a smartphone, tablet, or personal computer. 

Who Uses VoIP Technology?

Individuals and business owners use VoIP technology. Almost everybody can use it. According to Global Market Insights, the VoIP industry is expected to grow 15% year over year until 2027.

You’ve used VoIP technology if you’ve ever called anyone through your computer with Skype, Microsoft Teams, or Zoom. 

How to Identify a VoIP Caller?

Here are several ways to identify a VoIP caller:

  • Activate your caller ID. 
  • Use a reverse phone lookup service. 
  • Use CNAM (Caller ID Name) lookup. If the CNAM shows up when you receive VoIP calls, you can look it up.
  • If you’re using a softphone or deskphone, you can install and use a packet analyzer to show the IP address of the call and then look it up.
  • Look up the domain. Some VoIP calls show a domain associated with them.

VoIP Caller FAQs

Can you call back a VoIP number?

Yes. But it depends on the number.

If it is a fixed VoIP number, you can call back without issues. Legitimate callers want you to contact them, so there is no barrier.

If it is a non-fixed VoIP number, calling back can be difficult. Scam callers may disable them to prevent you from tracking them.

Does VoIP have a caller ID?

Yes, and you can enable it. 

Can people do VoIP Caller ID spoofing?

Yes, people can spoof Caller ID when using VoIP. Businesses may display a toll-free number for people to call back, even if it’s not their number from which they called. Spoofing, however, should not be used to defraud people.

How do I block VoIP calls?

To block VoIP calls:

  • Use the Do Not Call feature on the VoIP system. 
  • Register your phone with the national Do Not Call registry. It will help get rid of most unwanted calls. 
  • Make a complaint against the companies that make the spam calls.
  • Block calls through your router. Find out the VoIP application and ports the caller is using. Enter this information into your router’s control panel and block them.
