"Painless, easy onboarding. The software works great — both inbound and outbound calls. The thing that sets JustCall apart is the support. They're easy to get hold of and even configured a few integrations that weren't part of the normal setup. I've thrown some next-level problems at them, and they always get it done.

What people are saying about VoIP providers
VoIP phone service makes it possible to make and receive calls using the internet. It uses the Voice over Internet Protocol (VoIP) technology that converts voice into a digital signal and sends it over the internet, and in the process replaces traditional phone lines.
It works in four simple steps:
-
Conversion:
This is when your voice is converted from analog sound waves into digital data packets. -
Compression:
Next, these data packets are compressed for better transmission. -
Transmission:
The data is transmitted via the Internet. -
Conversion back:
At the recipient's end, these packets are decompressed and converted back to sound.
The entire process happens very quickly and securely, making VoIP phone calls the right choice for businesses in this digital world.
JustCall offers an all-in-one VoIP phone system that can make and receive calls in 70+ countries, at a fraction of traditional telephony costs.
"I enjoy its all-in-one solution with outbound and inbound communication. Everything can be analyzed from the dashboard within JustCall's website, and communication can be managed from the Dialer," says Evan T, a sales admin at Gutter Guys Plus and a happy JustCall user.(Source)

Frequently asked questions
What's the difference between VoIP and UCaaS?
While both VoIP and UCaaS use the internet to power communication, they serve different needs — VoIP focuses mainly on voice calls, while UCaaS offers a full suite of collaboration tools like messaging, video, and more. Understanding how VoIP and UCaaS differ can help you pick the right communication solution for your team. Here's a quick breakdown to make it easy.
| Feature | VoIP (Voice over Internet Protocol) | UCaaS (Unified Communications as a Service) |
|---|---|---|
| Primary focus | Voice calling functionality | Comprehensive communication across multiple channels |
| Core purpose | Replaces traditional phone systems with internet-based calling | Integrates multiple communication channels into a single interface |
| Feature set | Core phone features (calling, voicemail, transfers) | Voice, video, messaging, file sharing, team workspaces |
| Cost | Usually more affordable | Generally higher cost due to expanded feature set |
| Best for | Voice-centric communication needs | Integrated workplace communication experiences |
| Collaboration tools | Limited or basic | Extensive collaboration capabilities |
| Implementation | Typically simpler | More complex due to broader functionality |
| User training | Minimal (similar to traditional phone systems) | More extensive due to additional features |
| Remote work support | Good for voice communication | Comprehensive tools for full remote collaboration |
| Scalability | Easily scalable for voice needs | Scales across multiple communication channels |
Which is better for remote teams, VoIP or UCaaS?
Remote teams need to make calls from anywhere on any device, and VoIP is great for that. It lets your team handle calls easily without being tied to an office. But UCaaS goes further by adding messaging, video meetings, and team collaboration tools to keep everyone connected.
If your team mostly makes calls, VoIP is enough. But if you want to work together with chat and video too, UCaaS is the better choice. With JustCall, you can get both in one easy platform.
How to use voice over IP?
Using VoIP is easy, and chances are, your team already has everything they need to get started.
- 1. Choose a VoIP provider
- 2. Set up your account and add users, assign business phone numbers, and configure call flows or IVRs through a web-based dashboard
- 3. Use your existing devices like computer, smartphone, or optional IP desk phone.
- 4. Connect to the internet
- 5. Start calling
Is a VoIP phone system worth it for small businesses?
Definitely. VoIP systems like JustCall are built with small businesses in mind, helping you cut costs, grow quickly, and improve communication. You'll enjoy flexibility, mobility, and modern features like SMS, call tracking, and auto attendants without large upfront costs or bulky hardware setups.
How easy is it to switch from a legacy to a VoIP phone system?
Switching from a legacy phone system to VoIP is surprisingly straightforward with the right provider. There's no need to overhaul your existing setup or invest in bulky hardware; VoIP runs on devices your team already uses, like laptops, smartphones, or IP phones.
Your existing phone numbers can be ported over without disruption, and most providers guide you through the entire onboarding process, from setting up users and call flows to integrating your CRM or helpdesk tools. Because VoIP platforms are web-based and intuitive, minimal training is needed. Many companies run their old and new systems side by side for a short period for a smooth transition.
Is VoIP cheaper than landlines, mobile phones, and computers?
Yes, VoIP is generally cheaper than traditional landlines and mobile phone plans and it runs on devices your team already uses, like computers and smartphones.
-
Compared to landlines:
VoIP avoids costly line rentals, long-distance fees, and on-site PBX hardware. -
Compared to mobile plans:
With VoIP, you don't need to issue separate business phones or SIM cards. Teams can call and text using business numbers through a desktop or mobile app, cutting the need for extra devices or mobile plans. -
Compared to using computers alone:
Computers don't provide calling by default. VoIP turns them into full-featured business phones with call routing, IVR, SMS, analytics, and integrations.
How much do VoIP phone services cost?
VoIP phone services usually cost between $15 and $50 per user per month, depending on the features, support level, and provider. JustCall offers flexible pricing based on your business needs, starting from $29 per user per month.
Enterprise solutions with advanced AI capabilities are custom-priced based on specific requirements. All plans include essential features like dedicated phone numbers, unlimited domestic calling, and core integrations.
What makes VoIP more cost-effective than traditional telephony?
VoIP is more cost-effective because it runs over the internet without needing expensive phone lines, on-premise PBX hardware, and maintenance contracts. Here's what drives the savings.
- Lower monthly bills
- Minimal setup costs
- Add or remove users without expensive infrastructure changes
- No need to set up phone lines in different offices
- VoIP bundles calling, SMS, call routing, and integrations, reducing the need for multiple tools
Can I use a VoIP phone without a provider?
Technically, yes, you can make app-to-app calls without one, but you'll miss out on calling regular phone numbers and won't have access to advanced features. A provider gives you access to the PSTN, a secure infrastructure, constant support, and handy business tools like call logs, IVRs, and analytics, all you need for professional use.
Does VoIP require a service provider?
Yes, it does. If you want to make VoIP calls beyond your internal team, a service provider is essential.
They handle key things like call routing, voicemail, auto-attendants, number porting, HD call quality, and most importantly, connecting your calls to the public telephone network (PSTN). While it's possible to set up an internal VoIP system for team use only, you'll still need a provider if you want to reach customers or partners outside your organization.
The good news? JustCall offers an all-in-one VoIP platform that handles all of this — built for businesses of every size.
What types of VoIP providers are there?
The VoIP solutions market is quite diverse, with several categories of providers:
- Pure-play VoIP providers: Providers solely dedicated to VoIP phone services.
- Unified Communications providers: These offer VoIP along with video calls, messaging, and team collaboration tools in one platform.
- Traditional telecom companies: Old-school phone providers that now offer VoIP, often bundled with their existing services or as part of hybrid setups.
- Cable and internet providers: They use existing internet infrastructure to provide VoIP, usually packaged with business internet — convenient for small businesses.
- Open-source VoIP platforms: Highly customizable and low-cost, but they require more technical skills and in-house management to set up and maintain.
Each type of provider has its own set of advantages, so it's crucial to choose one that aligns with your organization's technical capabilities, budget, and communication needs.
Do I need hardware to run a VoIP phone system?
Not at all. VoIP works perfectly on regular smartphones, computers, and tablets. However, if your team prefers desk phones or works from a call center, you can opt for VoIP-enabled IP phones.
What equipment do you need for VoIP calling services?
The requirements are minimal. To start using VoIP calling, all you need is:
- A smartphone
- Laptop or a VoIP-enabled desk phone
- A stable internet connection.
What are the main uses of VoIP, and how is it cost-effective?
Businesses use VoIP for sales, support, and internal communication, allowing them to manage voice calls without the struggle and expense of traditional phone systems. Its core uses include:
- Internal and external calling
- Managing remote and hybrid teams with softphones or mobile apps
- Running support and sales teams with features like call routing, IVRs, call queues, and auto attendants
- Enabling global communication
- Centralizing communications across departments, offices, and time zones
- Integrating with CRMs and helpdesk tools
What makes it cost-effective is that VoIP eliminates the need for physical phone infrastructure. There's no PBX hardware, no on-site maintenance, and no per-minute long-distance rates. You simply pay a monthly fee per user, and the system scales as your team grows.
Businesses often see 50% to 75% in cost savings after switching to cloud-based phone systems.
Who has the best VoIP phone service?
For small and mid-sized businesses seeking a straightforward yet powerful platform with automation, CRM integrations, and global calling capabilities, JustCall is an excellent option. Our platform is designed for teams that want to be productive, stay organized, and provide outstanding customer experiences within the stipulated budget.
Is there a free VoIP service?
Skype and WhatsApp might help with free voice or video calls. But keep in mind, they only allow app-to-app calls and miss out on essential features that businesses really need, like call routing, analytics, and integrations. That's where JustCall comes in, offering pocket-friendly but feature-rich plans designed for small businesses.
Is VoIP reliable for business and personal use?
VoIP is incredibly reliable, especially when you have a solid internet connection. Many VoIP providers guarantee 99.99% uptime, global coverage, and crystal-clear audio. Unlike traditional systems, it's also resilient to disasters since you're not tied down to physical lines or hardware.
