Have you received a call whose caller ID said “VoIP caller”? Did you start looking for what VoIP caller means? Well, you have landed at the right place. In this blog, we will explain everything you need to know about VoIP calling and how VoIP technology can be helpful for your business. But first, let’s understand who a VoIP caller is.
Are you thinking about upgrading to a VoIP phone system?
What does “VoIP caller” mean on your caller ID?
A “VoIP caller” label on your caller ID means the incoming call is being placed over the internet using Voice over Internet Protocol (VoIP) technology, rather than a traditional landline or cellular network. The label appears because VoIP providers often don’t link the phone number to a verified name registry so your phone can’t display the caller’s identity.
VoIP, or voice-over-internet protocol, is a technology that enables you to place calls online as opposed to over a traditional phone line. ( Check out this comparative guide on Traditional vs. Digital vs. VoIP Phone System for more clarity). The VoIP technology will link you to any phone in the globe by turning your voice into a digital signal transmitted over the internet. It is turned back into a standard phone signal connecting you with whom you are calling.
When using the VoIP platform, you dial a phone or a VoIP number and call it online. The receiver’s phone will ring as if it were coming from another phone, with the possible exception that the caller ID may read “VoIP caller.”
VoIP caller software provides multiple capabilities, including caller identification and screening, simple digital file exchange, etc.
As per Future Market Insights, the VoIP services market revenue by the end of 2021 was US$ 123.3 Bn. The VoIP services market is expected to reach US$ 354.7 Bn by 2032. Additionally, it is estimated to grow at a CAGR of 10.2% for 2022-2032.
How Do VoIP Callers Make Calls?
VoIP calls work by converting your voice into digital data packets, transmitting them over the internet using TCP/IP protocols, and reassembling them as audio on the receiver’s end. If the receiver uses a traditional phone, a VoIP gateway translates the data back into a standard phone signal all in under 150 milliseconds.
A VoIP caller sends your audio signal over a broadband internet connection.
VoIP technology transforms your speech into data packets transmitted across internet fibers until they reach the receiver. The data packet is converted into audio and connects directly with the receiver if you contact another VoIP phone line. If you call traditional phones, the data packets are transformed into ordinary phone signals before they reach the user.
VoIP phone systems use TCP/IP and Intelligent Endpoint protocols. Your audio is divided into data packets by TCP and sent over the internet’s fiber optic connections by IP. The receiver is located and given signals using the Intelligent Endpoint protocols.
IN SIMPLE WORDS,
Think of VoIP as sending a voice message over the internet. Like sending an email, your voice is turned into data, sent across the web, and then turned back into a voice for the person on the other end to hear.
Types of VoIP Numbers
VoIP numbers come in two types – fixed and non-fixed.
Fixed VoIP numbers are linked to a specific geographical address. This linkage provides a level of security and is often required by businesses that need a solid local presence.
Real-life example:
A local bakery using a fixed VoIP number ensures customers calling in will recognize the area code, reinforcing the bakery’s community connection.
Non-Fixed VoIP Numbers offer flexibility as they are not tied to a specific location. This means you can choose a number that suits your business needs, whether it’s sticking with a local presence or going global without the physical ties.
They’re perfect for digital nomads, international businesses, or anyone needing a global presence without the overhead of physical offices.
Real-life example:
Imagine a freelance graphic designer based in New York who serves clients in London and Tokyo. A non-fixed VoIP number allows the designer to establish local contact numbers in each city, making it easier for clients to reach out.
How To Use VoIP Caller Technology?
If you need VoIP for personal settings, you can easily download one of the VoIP caller software available in the market and start using VoIP technology for your business. All you need is an internet connection and a device.
However, if you need a custom VoIP solution for your business, you need to choose reliable VoIP development services to develop one for you. Additionally, VoIP solution development can benefit your business more than you think. You can include appealing, affordable features like call forwarding, auto-attendant, and call encryption, which may make them a better alternative to a traditional phone line.

Encountering issues with your VoIP service can be frustrating, but don’t worry! Most problems have simple fixes that can get you back to clear calls in no time. Here are some simple, practical solutions to common VoIP calling problems:

- Poor Call Quality: Check your internet speed and network stability. Being a VoIP caller, you require a stable connection. Consider upgrading your internet plan or using Quality of Service settings to prioritize voice traffic.
- Connection Issues: Ensure your VoIP caller software or hardware is correctly set up and you’re using the latest version. Restarting your device or software can often resolve connection problems.
- Echoes: Use headphones to minimize echo.
- Delays: Delays often indicate network congestion—try calling at a different time or optimizing your network setup.
Also, integrating VoIP into your business doesn’t mean parting ways with your existing traditional phone system overnight. You can enjoy the best of both worlds with a hybrid enterprise VoIP solution.
This approach involves setting up a VoIP gateway that connects your traditional system to the internet, enabling VoIP calls alongside conventional telephony. This setup allows for a gradual transition, letting your business test and adapt to VoIP functionalities while maintaining its current infrastructure.
How do you identify a VoIP caller & Block them (4 methods)?
You can identify a VoIP caller in four ways:
(1) check your phone’s caller ID for a “VoIP” or unnamed label
(2) use a reverse phone lookup tool like Truecaller or Whitepages
(3) ask your carrier for call metadata
(4) look up the number’s carrier via a free online “VoIP number checker.”
A user gets given a VoIP number that they can use to access VoIP services. You can recognize VoIP caller software by turning on caller ID or checking the VoIP number. Activating caller ID software, such as Truecaller, causes the ID to be automatically looked up and displayed.
You may trace the caller’s number while on the line during a call, ask your VoIP service provider for more information, or use a reverse phone lookup tool.
How do you block a VoIP caller? (iPhone, Android, landline)
To block a VoIP caller, open your phone’s recent calls list, select the number, and tap “Block this caller” (iPhone) or “Block/report spam” (Android). For landlines, contact your carrier to request a number block. You can also install third-party spam-blocking apps like Hiya, Truecaller, or RoboKiller for automated filtering.
Utilizing the blocking tools on your smartphone is the most straightforward approach to prevent VoIP spam. Each device has a different policy. Selecting the number and clicking “Block number” is sometimes all required. In other cases, you might need to contact your supplier of a traditional phone system and request that a number be blocked.

Is a VoIP caller a scam?
Not always. Many legitimate businesses use VoIP, but scammers also exploit it because VoIP numbers are cheap and easy to spoof. Verify unknown callers through their official website before sharing information.
Can you trace a VoIP caller?
Yes, but it's harder than tracing landline calls. Law enforcement can trace VoIP calls through the provider's records. Individuals can try reverse lookup tools like Truecaller or request metadata from their carrier.
Why does my caller ID say "VoIP caller" instead of a name?
VoIP providers typically don't verify user identities, so no name is registered with the number. Your phone displays "VoIP caller" as a fallback when no Caller Name (CNAM) record is found.
Is VoIP calling free?
VoIP calls between two users on the same platform (like WhatsApp or Skype) are free over Wi-Fi. Calls to landlines or mobile numbers usually require a paid VoIP subscription, though rates are significantly lower than traditional services.
Do VoIP calls go through a cell tower?
No. VoIP calls travel over the internet via broadband, Wi-Fi, or cellular data not through dedicated voice cell towers.
Can VoIP work without internet?
No. VoIP requires an active internet connection. Without it, calls cannot be placed or received. Some business VoIP systems use cellular data as a backup
Is VoIP more secure than a landline?
VoIP can be more secure when properly configured with TLS encryption, SRTP, and STIR/SHAKEN authentication. However, unconfigured VoIP systems are more vulnerable to eavesdropping than traditional landlines.
What's the difference between VoIP and SIP?
VoIP is the broader technology for voice calls over the internet. SIP (Session Initiation Protocol) is the signaling protocol most VoIP systems use to set up and end calls. All SIP calls are VoIP, but not all VoIP calls use SIP.
