Frequently Asked Questions

Introduction

You cannot build a successful business if you are unable to swiftly and efficiently connect with your partners, clients, and coworkers. You need a good company phone system to function. Fortunately, this can be made easier than before with free telephone services.

Additionally, a lot of these programs offer extra advantages and benefits that may be quite helpful. How can one pick the best service, though? Does anyone have any free ones? Our list of the top free VoIP telephone services for 2025 can be found here.

Is there a VoIP service that is free?

Certainly, but there’s a catch. Free VoIP services are available for personal use, however, the functionality offered to commercial users is typically severely limited or nonexistent. Therefore, the best course of action is usually to choose a program that isn’t totally free but is reasonably priced, has some extra features (like call recording and call transferring, for instance), and has good customer service.

Many services, even for private use, only let you call other subscribers of that specific product; calling a number typically entails some extra fees (if it’s feasible at all). Other restrictions are used by certain free VoIP companies (such as permitting just inbound calls).

In summary, if you’re not ready to pay, don’t expect unlimited calling.

How do I get free access to a free VoIP?

For personal use, it’s usually fairly simple: you simply need to download & install the selected software on your gadget (a computer, a cell phone, or any other portable device), establish an account on the website or through the program, log in, and then follow the prompts to set up an account or a number so that you can call people. Remember that, depending on the service, there may be restrictions on the number of localizations you are able to call and the duration of calls, among other limitations.

The top VoIP phone services for free in 2025

Ringblaze reviews

Based on six evaluations, Ringblaze’s Capterra rating is 3.5.

“The program integrates VoIP & website call widgets that are added to your website. Having your own business telephone number and being able to make and receive calls directly from your browser are two features of Ringblaze. This will make it easy for clients and guests to call the customer service number directly from within that widget. You can easily use the user interface. The team’s commitment to understanding consumer wants and incorporating those features into the product is the best part of their plans to improve this product” – Virgil V.

2. OnSIP

Even if OnSIP is among the least well-known companies on this list, it is still worthwhile to check out the service. The product was created with smaller businesses in mind. It is similar to a conventional phone service in many aspects. Still, it has a few extra capabilities on top, such as voicemail-to-email functionality, auto attendants, video chat & conference calls, call management, & queue reporting, to mention a few.

What is the price of OnSIP?

OnSIP offers a trial period for free for the premium version in addition to a limited-time free version. The monthly starting price is $18.95, and there are many plans with a little varied pricing structure.

Features of OnSIP

Support for OnSIP

You can contact OnSIP by phone, chat, or email. A help desk is also available, and you may utilize the knowledge base, forums, and frequently asked questions.

Pros

Despite its drawbacks, it’s among the most accessible free VoIP services available.
Making and ending conversations is simple thanks to a useful widget.
Basic calling guidelines, such as call segregation and timetables, can be established.

Cons

Only incoming calls are supported by the free VOIP version; while it might be adequate for certain fundamental customer support, it is not a complete solution.

OnSip Reviews

According to 8 reviews, OnSIP possesses a 4.6 rating on Capterra.

“I’ve had an excellent experience with OnSIP. They have great customer service. Every time, I’ve gotten just what I needed. My personal coach periodically checks up on me to make sure everything is going smoothly. I strongly advise you to use this affordable service for your home-based business!” – Abigail K.

3. Google Voice

Google doesn’t require an introduction. The company that created the world’s most successful search engine, YouTube (when it was acquired in Nov 2006), the Chrome browser, and the Android operating system is one of the biggest forces in the tech sector. Though it’s a lesser-known offering, Google Voice is an intriguing choice for VoIP calling service seekers.

What is Google Voice’s price?

For individual usage, the facility is free. The starting price for the business version is $10, though calls may cost extra based on localization.

Features of Google Voice

Cloud-based: compatible office phones, laptops, and mobile devices
Spam calls are automatically blocked.
Scalable with ease (ring groups, etc.)
Transcription of voicemails
Integration with Google Calendar
Integration with Google Meet
Accessible as a mobile application or web application

Support for Google Voice

The website has a forum and a special help area with answers to commonly asked concerns and fixes for common issues.

Pros

The behemoth that created YouTube, Android, Chrome, and the search engine is Google.
Free for individual use
As part of the membership package or for free, you receive a local phone number.
The simplicity

Cons

Google is the behemoth that created OnHub, Play Music, & Datally. Do you not recognize these? That’s what the point is.
It only functions in a few places (mostly the United States), where you can obtain a Google telephone number, though in some other locations, the service can be utilized as a component of G Suite). Before selecting Google Voice above other alternatives, be sure it is currently supported.

Reviews of Google Voice

Google Voice is rated 4.5 according to 221 reviews on Capterra.

“For the past five or more years, I’ve kept my personal and work conversations apart by using a landline number for my business phone in my home office. (As well as to keep me from becoming sidetracked by business calls or texts while trying to spend moments with friends and family.) The price of landline services in my new neighborhood astounded me after I recently moved. Since the salary was excessive, I began searching for other options. Google Voice provides me with a local telephone number at no cost, which is why I chose it.” – Signe J.

4. Skype

Perhaps the most popular and long-standing VoIP service available is Skype. Both personal and professional users find it useful, and it may be set up on a variety of platforms. The quality of the sound & video offered by the service is decent but not exceptional. It should be quite easy to use because most issues have been discovered and fixed due to its lengthy existence on the market, or at the very least, people have discovered workarounds.

What is the price of Skype?

Skype’s basic version is free, and there are no fees associated with calling other Skype members. You may need to pay, though, if you wish to use any of the features, such as calling telephone numbers in different nations. Costs vary greatly depending on the plan and location (unlimited calls in the United States cost $7.99, for example).

Features of Skype

Access Permissions/Controls
Call Recording
Automatic Transcription
Contact Management
Collaboration Tools
Electronic Hand Raising
Drag & Drop
Mobile Access
File Sharing
Online Voice Transmission
One-to-One Messaging
Presentation Streaming
Recording
Real-Time Chat
Screen Sharing

Assistance for Skype

Skype has a large and vibrant community, which is an excellent location to check for issues. Additionally, you can use the technical support website, connect with a virtual agent for assistance, and use a dedicated contact form to speak with company representatives directly.

Pros

Renowned brand
Nice audio quality
The choice to obtain a phone number
Calls between Skype users are free.

Cons

When it pertains to call quality, there are better options (particularly video).
UI is a little out of date.
Can waste a lot of resources, including bandwidth and processing power on your device.
Microsoft Teams has supplanted Skype for Business, so it is no longer truly a business product.

Skype reviews

Based on three evaluations, Skype’s rating on Capterra is 4.0.

“Although Skype is a fantastic communication tool, there are alternative programs that provide the same functionality as well as additional helpful functions that Skype does not. The program is simple to use in a business context because almost everyone is familiar with it. It’s a fantastic platform for group chats and video conferences. We additionally utilize it for a lot of calls abroad. They must, however, provide more functionality (for instance, you can’t speak with other callers during an online conference unless you utilize other platforms). Additionally, it would be preferable if there had been a calendar—rather than only a list—that displayed the calls we had planned for the month.” – Cielo Kaye M.

5. Zoom Phone

Zoom has established a strong market position in the past few years, and this is no fluke. It is a robust and reasonably priced conference system that caters mostly to business users. Although online conference calls are Zoom’s primary focus and most well-known offering, the firm also offers Zoom Phone. Here, the plan was to make a phone service based on the features that were successful on the top platform.

A convenient VoIP service that should meet the needs of numerous clients is the final result.

What is the price of the Zoom Phone?

There is a free VOIP version of the main Zoom service. The monthly fee for the Zoom Phone program is $10.

Features of Zoom Phone

Access Permissions/Controls
Automated Attendant
Call Monitoring
Call Logging
Call Routing
Call Recording
Employee Directory
Contact Management
Mobile Access
IVR Recognition
PBX
Online Voice Transmission
Unified Communications
SIP Trunking
Video Conferencing

Support for Zoom Phones

A wealth of useful resources, including a number of video lessons, may be found on the large support website for Zoom & Zoom Phone. The personnel can also be contacted by phone or online ticketing.

Pros

An intuitive, well-designed interface
Excellent sound quality
Reputable brand

Cons

During a conversation, users are unable to switch between VoIP and the phone.
Sometimes lags

Reviews of Zoom Phone

From its 114 reviews, the Zoom Phone gets a rating of 4.5 on Capterra.

“Our users are actually utilizing their phones and they enjoy them again. We also have call logs that are correct for the very first time in a long time. Simply said, Zoom Phone functions. Compared to 4G cell service, it is clearer. Using the interface is simple and intuitive. The functionality of the set is unparalleled. More than anything technological, Zoom has to do more to market its phone device. The Zoom Video product’s management is a little haphazard. Incorporating a combination of each of them on the back end would be a significant enhancement.” – Anonymous reviewer.

Maintain communication with your clients

Maintaining relationships with others is more important than ever in these trying times. These days, we can accomplish that fast, easily, and without paying excessive fees thanks to the technology at our disposal. VoIP phone solutions are among the best cases of this; you can use them to communicate with almost anyone in the world, though most of the time, based on the service, there are certain restrictions.

VoIP telephone services have the additional benefit of enabling you to connect with others who may not have Internet access. As in 15 to 20 years ago, you can simply connect to their phone number and give them a call. The advantages for both individuals and businesses are enormous. Regretfully, this feature is typically either inaccessible for free or so restricted that using the service in this manner no longer makes sense.

In certain cases, such as this one, it makes more sense to pay a little more for a quality product and assistance rather than attempting to get the same thing for nothing. Here’s where issues get a little trickier: the important thing is to pick the one that works best for you.
