# Best VoIP Providers

  *By [Nana Serwah Nkrahene](https://research.g2.com/insights/author/nana-nkrahene)*

   Voice over Internet Protocol (VoIP) software transmits phone calls over an IP network without relying on traditional telephone infrastructure, functioning as a modern alternative to private branch exchange (PBX) systems. It helps organizations cut communication costs, support remote work, and maintain secure calling capabilities.

### Core Capabilities of Voice over Internet Protocol (VoIP) Software

To qualify for inclusion in the VoIP category, a product must:

- Provide VoIP PBX systems for businesses or offer a VoIP softphone application
- Include features that help manage incoming calls, such as call forwarding, call transferring, and routing
- Enable real-time network monitoring via dashboards
- Offer integration compatibility with communication and CRM platforms

### Common use cases for Voice over Internet Protocol (VoIP) Software

VoIP software supports scalable, reliable communication for internal collaboration and customer-facing interactions. It also benefits teams using related tools such as [video conferencing software](https://www.g2.com/categories/video-conferencing), [UCaaS platforms](https://www.g2.com/categories/ucaas-platforms), [contact center software](https://www.g2.com/categories/contact-center), and [CRM systems](https://www.g2.com/categories/crm).

### How Voice over Internet Protocol (VoIP) Software Differs from Other Tools

VoIP differs from traditional PBX by replacing legacy on-premises telephony systems with IP-based calling, reducing infrastructure and maintenance costs while improving flexibility for remote and hybrid teams. Compared with broader UCaaS platforms, VoIP primarily focuses on voice calling, softphones, and SIP-based PBX functionality, though VoIP is typically a core component of most UCaaS offerings.

## Buyer Guide

### What You Should Know About VoIP Software

### What is VoIP software?

Voice-over-internet protocol, or VoIP, is a communication technology that allows audio and video interaction over the internet. It is a mode of phone transmission that enables internet phone calls using any smart device as opposed to traditional telephone services.

[VoIP](https://www.g2.com/glossary/voip-definition), often pronounced as “vŏy'p” or “V-O-I-P,” is also commonly called voice-over IP. VoIP software enables online calling using digital signals, making it a more cost-effective alternative to traditional phone lines. It includes functions such as automated calls, phone and video calls, call queuing, and screen sharing. VoIP relies on a fast and dependable internet connection, and it can be understood as an “internet telephone" in layman’s terms.

VoIP providers, also known as virtual phone systems, can help companies significantly improve call quality and reduce communication costs. VoIP solutions streamline communications and standardize the workflow, enabling companies to make international or overseas audio and video calls without expensive payments. It’s also a more flexible solution that allows employees to communicate long distances when away from their typical office space.

### Who uses VoIP software?

Generally, VoIP calls can be accessed by everyone. Although most people use video calling platforms for personal use, VoIP products are adopted by large corporations. More options are available with advancements in technology and VoIP itself, especially regarding professional solutions for meetings and conferences with ethernet. VoIP software is often used in the following industries: 

- **Customer service:** VoIP services have nearly taken over this industry, with customer service centered on phone lines. It reduces wait time by automatically redirecting calls to available people. It also has live monitoring and data-collecting capabilities, making it ideal for this type of work.
- **Hotel and tourism:** The backbones of this sector are effective communication and 24-hour service. For best customer satisfaction, hotels use VoIP services to assist in managing calls and avoiding congestion on a single line at a time.
- **Healthcare:** Healthcare industries use cloud-based VoIP phone systems to book online consultations with doctors, patient registrations, floor-to-floor communications, inventory management, etc. 
- **Financial institutions:** Besides assisting with encrypted communication and authentication, VoIP allows finance professionals to communicate in real-time with their peers and customers. It also provides its consumers with financial data, news, and evaluations, which is necessary for making informed investment decisions.
- **Manufacturing:** Manufacturing includes a variety of fields such as finance, accounting, sales, and warehouse, making it an industry for VoIP networks. Employees benefit significantly from VoIP software features like instant messaging, video conferencing, file sharing, advanced voice call management, etc., which enable effective telecommunication and collaboration. 

### What types of VoIP software exist?

Five types of VoIP services are available in the market for interested buyers. 

- **Residential VoIP services:** The landline phone is linked to a Wi-Fi modem via an adapter to make and receive internet calls. Charges are set according to different plans. Example: VoIP.com and Lingo.
- **Device-based VoIP services:** To make free calls within the United States involves purchasing a VoIP device from a service provider and connecting it to an already-owned device. This removes the requirement for equipment other than a conventional landline phone and a monthly fee. Example: MagicJack and Ooma.
- **Software-based VoIP services:** This is the most commonly used VoIP service. It requires a web-based application online or installed PC software. It’s then used via the computer's audio input and output devices. Example: Skype and Zoom.
- [Mobile VoIP services](https://www.g2.com/categories/voip/f/voip-number) **:** Mobile VoIP is an application installed on mobile phones, allowing call access from anywhere with a reliable internet connection. Example: WhatsApp and Google Hangouts
- **Business VoIP services:** The two VoIP choices for businesses are on-premises and cloud-based. Both offer far more cost-effective communication options than traditional landlines and have several valuable features. These include video and audio conferencing services, screen-sharing, interactive voice response, automated attendants, call queues, and call reports. These often expandable features come with comprehensive technical assistance.

### What are the benefits of VoIP software?

- **Cost-effective:** An important advantage of VoIP technology is its low-cost hardware and software. This also decreases the need to buy more smartphones and or other gadgets.
- **Reliable:** While traditional or regular phone systems can be prone to failures, [unified communication systems (UCaas)](https://www.g2.com/categories/ucaas-platforms) are often backed by multiple data centers, preventing an outage. Even if a business has issues with its internet connection, incoming calls can always be routed to mobile devices, even if the power or internet connection fails.
- **Flexibility:** Users of VoIP systems can add and remove phone lines as required, and unlike traditional landline phone systems, removing or adding VoIP lines requires little effort and time.
- **Integration:** IP phone systems integrate seamlessly with several existing business platforms. Many VoIP systems, for example, integrate with [customer relationship management (CRM)](https://www.g2.com/glossary/crm-definition) tools, benefitting both large and small enterprises. Businesses can reap the benefits of VoIP software without modifying current applications or IT infrastructure.
- [Remote access:](https://www.g2.com/glossary/remote-access-definition) VoIP makes calling from anywhere using any device possible. This is becoming more important with remote work. Every user in the VoIP system has a unique [VoIP number](https://www.g2.com/categories/voip/f/voip-number) assigned to them. Using this number, the user can place and receive calls in the office or from home. VoIP software can be used on any mobile device, including phones and laptops across Apple and Microsoft.
- **Advanced features and settings:** VoIP can offer premium company management services such as auto attendants, [call recording](https://www.g2.com/glossary/call-recording-definition), and call queuing. With custom VoIP services, companies can design a system to match their needs. 

### What are the challenges with VoIP software?

- **Network dependency:** VoIP tools require a reliable network infrastructure for successful integration. VoIP relies on an internet connection to exchange voice data packets, and network failures can significantly impact call quality and reliability. Businesses should assess the stability of their network infrastructure and identify potential bottlenecks such as insufficient bandwidth, network overload, or unreliable connections. ** **
- **Bandwidth and internet connection:** Insufficient bandwidth or inconsistent internet access while using VoIP solutions leads to poor phone service, failed calls, and latency issues. Working with an internet service provider (ISP) that provides dedicated bandwidth or employing traffic prioritization techniques such as quality of service (QoS) can enhance VoIP speed.
- **Security and firewall configuration:** VoIP deployments are prone to eavesdropping, toll fraud, denial-of-service attacks, and other security issues. Robust security strategies such as [encryption](https://www.g2.com/articles/what-is-encryption) protocols, firewalls, and intrusion detection systems must be implemented to protect VoIP networks. Since configuring these can be challenging, businesses must work with IT specialists or VoIP service providers to ensure correct firewall settings and security best practices are implemented.
- **Power supply and backup:** Unlike traditional private branch exchange (PBX), VoIP requires a consistent power source. Power outages can render VoIP systems inoperable, causing communication routes to be disrupted and company operations to suffer. Power outages can be reduced by deploying uninterruptible power supply (UPS) devices or backup power generators. Furthermore, organizations should consider establishing [failover](https://www.g2.com/articles/failover) solutions, such as automated call routing to mobile devices or alternate sites, to ensure ongoing availability during power outages.
- **Staff training and user adoption:** Effective training and user acceptance approaches are essential when adopting a new communication system. Employees may be inexperienced with VoIP systems instead of traditional phone systems, resulting in reluctance or difficulties adapting to the latest technology. In addition, due to protocol differences, data formats, or compatibility issues, integrating VoIP systems with existing corporate applications may be problematic. Provide substantial training sessions, user manuals, and regular assistance to employees using VoIP solutions. 

### What are the common features of VoIP software?

VoIP provides a variety of features that facilitate communication. While specific features differ between providers and plans, the following are some common features found within UCaaS platforms and VoIP:

- **Phone calls:** VoIP telephony allows users to place phone calls online. As a result, organizations can benefit from a low-cost, dependable, and portable solution. Internet calls are ideal for businesses with remote or field employees.
- [Instant messaging](https://www.g2.com/categories/voip/f/instant-messaging) **:** Users of VoIP software can send and receive instant messages over the internet, which benefits customer support and internal communication. Employees can discuss an action item or touch base informally via texting, improving cooperation, productivity, and team engagement.
- [Screen sharing](https://www.g2.com/categories/voip/f/screen-sharing) **:** VoIP software allows users to share screens in real-time, saving time and increasing productivity. Screen sharing is often used for collaboration and presentations, which is helpful for hybrid and remote workers.
- **Call monitoring:** VoIP software allows businesses to monitor, record, and track calls, helping companies simplify customer service and enhance performance.
- **Caller ID:** VoIP service providers display the name and phone number of incoming callers, allowing users to see who is calling.
- [Video conferencing](https://www.g2.com/glossary/video-conferencing-definition) **:** Users can utilize VoIP software to make video calls via the Internet, which can lower operational and travel expenses by eliminating the need to travel for meetings. Video conferencing also benefits users by boosting distant worker engagement and cooperation.
- **Desk-to-desk calls:** VoIP software enables users to contact one another through mobile phones and landlines. This helps maintain communication flow, which is important when multiple users handle a single call. For example, a call center would benefit from VoIP technology as transferring customers on time would be much easier. 
- [Conference calls](https://www.g2.com/articles/conference-call) **:** Users can host conference calls – which enables multiple users to make phone or video calls over the internet at once. This is essential for team collaboration and communication with remote workers.
- [VoIP phone number](https://www.g2.com/categories/voip?utf8=%E2%9C%93&order=g2_score&filters%5Bverified_features%5D%5B%5D=2144) **:** VoIP telephony offers users a unique phone number that can be dialed anywhere. Unique numbers are great for businesses that don’t have a landline but want to have a number that reflects their location.

Many VoIP providers will also offer the following features: 

- [VoIP providers with software pairing capabilities](https://www.g2.com/categories/voip/f/software-pairing)
- [VoIP providers with automated attendant capabilities](https://www.g2.com/categories/voip?utf8=%E2%9C%93&order=g2_score&filters%5Bverified_features%5D%5B%5D=2143)
- [VoIP providers with browser extension capabilities](https://www.g2.com/categories/voip/f/browser-extension)
- [VoIP providers with hold music capabilities](https://www.g2.com/categories/voip/f/hold-music)
- [VoIP providers with individual download capabilities](https://www.g2.com/categories/voip/f/individual-download)

### VoIP software pricing

A VoIP phone system typically costs between $25 and $35 per line monthly. Call recording, toll-free lines, and equipment rentals are optional extras. 

These expenses can be divided into "recurring" and "one-time" charges. Subscription fees and per-user or per-line prices are the most common recurring expenses, whereas setup and equipment costs are often one-time expenses.

Call forwarding, voicemail, and domestic calling are common VoIP features included in the standard subscription rates. It is expected to have unlimited outgoing and receiving calls across the country.

Advanced features such as CRM integration, complex analytics, unlimited calling, international calls, and premium customer support will entail extra charges. Defining and budgeting for the fundamental components of business operations is critical.

### How to choose the best VoIP software?

When purchasing a VoIP solution, it is crucial to determine if an on-premises or cloud-based solution is better suited for the business. Cloud-based or hosted VoIP software typically requires no additional hardware and delivers calls to phones installed at the business, but it comes with a higher monthly cost than onsite VoIP options. Furthermore, most cloud-based VoIP products offer mobile applications that integrate with business phones, allowing users to make and receive calls using a data connection while traveling.

On-premises or onsite VoIP systems require supplemental hardware that must be purchased upfront. Still, it can compensate for this by offering a lower monthly cost, additional security, and more flexibility during setup. Onsite VoIP systems need an IP-PBX and a public switched telephone network (PSTN) gateway device to function correctly. The IP-PBX routes calls to the correct phones on the web, while the PSTN gateway device converts calls from the analog voice signals of the PSTN to digital signals for the IP-PBX and back, as necessary.

Whether a company is just starting to explore VoIP software or is looking for a more appropriate solution for their needs, [G2](https://www.g2.com/) can help inform buyers of the market and assist them in selecting the best software product for their business.

#### Requirements gathering (RFI/RFP) for VoIP software

A buyer should assess the needs of their organization when deciding on the kind of VoIP software to purchase. Does the organization already use this kind of software? Is this the first time the organization will be using VoIP software? If that’s the case, buyers must determine how they plan to implement this software and what features the organization will need. 

Some points to consider are:

**Company size **

Buyers will need to ensure that the products they are looking at will suit the size and needs of the organization. Ensuring the product has the appropriate flexibility and scalability to adapt to changing conditions is essential when purchasing software.

**Integration requirements**

Buyers must know which business systems require integration with a new VoIP system beforehand. For example, will the product need to be integrated within existing systems, such as CRM or ERP platforms? Some VoIP products may come with [application programming interfaces (APIs)](https://www.g2.com/glossary/api-definition) for integration with specific software. However, other phone systems do not offer this capability.

#### Compare VoIP software products

**Create a long list**

The first step to finding the perfect software solution is to create a preliminary list of products that fit the buyer’s general needs. The next step is to narrow down the list by selecting specific features that are must-haves or requirements for the buyer. G2.com provides information about the best VoIP software, allowing buyers to filter options and user reviews to help narrow the product list to a more relevant selection.

**Create a short list**

Shortlisting software products is an essential step in buying. While it may be daunting to filter through various products, users can get help by utilizing [G2’s compare](https://www.g2.com/compare) feature. This feature will take products of choice and display them side by side so the buyer can quickly determine which software ticks the essential boxes on the list. 

**Conduct demos**

Once the buyer has narrowed down the product list, the next step is to conduct a demo. Demos allow buyers to see a product and its features in more detail. Buyers should have a business scenario ready to test the product thoroughly. Additionally, buyers should inquire about cost, vendor support, and any concerns about the product.

#### Selection of VoIP software

**Choose a selection team**

VoIP software is efficient and widely used in many businesses. With that in mind, a good starting point would be to select three to five team members from various departments (such as IT, management, sales, etc.) and seniority levels to be part of the selection team. The more varied the selection team is, the better a company can assess how well a product will meet their needs. 

**Negotiation**

Once the selection team has narrowed their software picks, it’s time to discuss customization options, pricing, and the type of support the vendor needs. It’s always important to address pricing options, even when they are listed on a vendor’s website. Many software vendors will provide discounts and custom pricing options based on what the buyer is looking to purchase. 

**Final decision**

Before making the final decision on a product and moving forward with a purchase, utilizing a free trial and conducting a last demo can give a buyer an additional sense of security and confidence when making a final decision.
