# Best VoIP Providers - Page 12 *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. ### Insights from G2 on Voice over Internet Protocol (VoIP) Software Based on category trends on G2, VoIP's reliability, cost savings, ease of remote access, and the convenience of softphone options that replace or supplement physical desk phones. ## How Many VoIP Providers Products Does G2 Track? **Total Products under this Category:** 418 ### Category Stats (May 2026) - **Average Rating**: 4.36/5 (↑0.01 vs Apr 2026) - **New Reviews This Quarter**: 579 - **Buyer Segments**: Small-Business 57% │ Mid-Market 35% │ Enterprise 7% - **Top Trending Product**: Phone2 (+1.976) *Last updated: May 13, 2026* ## How Does G2 Rank VoIP Providers Products? **Why You Can Trust G2's Software Rankings:** - 30 Analysts and Data Experts - 60,300+ Authentic Reviews - 418+ Products - Unbiased Rankings G2's software rankings are built on verified user reviews, rigorous moderation, and a consistent research methodology maintained by a team of analysts and data experts.

I recommend starting with the calls your team handles most often. If inbound support matters most, prioritize routing, voicemail, missed-call handling, queues, and reporting. If sales outreach is the main use case, focus on CRM sync, call recording, SMS, notes, and follow-up tracking. For distributed teams, test desktop and mobile reliability before committing. ### What do VoIP Providers do? I usually describe VoIP providers' software as cloud-based business phone software for calling. These systems help teams make, receive, route, record, and manage calls across desktop, mobile, and connected devices. Reviewers often connect this category with business numbers, voicemail, SMS, call history, call routing, recordings, and CRM activity. It gives sales, service, and admin teams a cleaner way to manage phone communication across people, locations, and devices. ### Why do businesses use VoIP providers? Across the review data I analyzed, businesses used VoIP Providers when phone work needed to be easier to manage across devices, locations, and teams. Users often describe the value in calling from a computer or mobile app, keeping a dedicated business number, and reviewing past call activity from one system. The main benefits I saw were: - Reviewers like quick setup, simple calling, and business numbers that work across devices. - Sales and service teams value call recording, SMS, voicemail, and CRM call logging. - Admins appreciate user setup, number assignment, routing, and account visibility. - Users often call out support quality when porting, call issues, or billing questions come up. Common pain points include call quality, app freezes, number registration, text setup, pricing, and support follow-through. ### Who uses VoIP Providers primarily? After examining G2 reviewer profiles, I found that VoIP Providers software supports the following users: - **Sales teams:** Place calls, send texts, record conversations, and log follow-up activity. - **Customer service teams:** Manage inbound calls, voicemail, routing, and missed-call follow-up. - **IT admins:** Add users, assign numbers, configure routing, and manage permissions. - **Healthcare offices:** Use business lines for patient communication and appointment-related calls. - **Legal and real estate teams:** Keep client communication tied to dedicated business numbers. - **Small business owners:** Separate business calls from personal phone activity. ### What types of VoIP Providers should I consider? Based on the way reviewers describe the category, I see VoIP Providers falling into these groups: - **Cloud business phone systems:** Best for replacing desk phones with desktop and mobile calling. - **Contact-center-style systems:** Best for routing, queues, call monitoring, and service workflows. - **Sales calling tools:** Best for CRM sync, recordings, notes, call history, and outbound follow-up. - **Virtual number providers:** Best for small teams that need separate business lines or local numbers. - **Unified communication suites:** Best when calling needs to sit beside meetings, messaging, and collaboration. ### What are the core features to look for in VoIP providers? Based on my review of this category, all the strong platforms tend to include core features like: - Business number setup, porting, extensions, and number assignment across teams and locations. - Desktop and mobile calling, voicemail, SMS, and call forwarding as core communication coverage. - Call routing, IVR, queues, missed-call handling, and recording for structured inbound management. - CRM sync, call notes, transcripts, analytics, and searchable call history for post-call visibility. - Admin controls covering users, permissions, billing, devices, and compliance requirements. - Accessible support for outages, porting delays, call quality issues, and text approval processes. ### What trends are shaping VoIP providers right now? From my evaluation of review patterns and current communication platform updates, these themes stand out: - **AI call summaries:** Phone systems are adding summaries, action items, and transcripts to call history. - **UCaaS consolidation:** Buyers are comparing voice, messaging, meetings, and collaboration in the same buying cycle. - **Mobile-first calling:** Distributed teams expect business calling to work reliably across desktop and mobile apps. - **CRM-connected call records:** Sales and service teams want calls, notes, and follow-up history tied to customer records. - **Admin-controlled AI and compliance:** Teams need control over recordings, transcripts, summaries, retention, and access. --- ## What Are the Top-Rated VoIP Providers Products in 2026? ### 1.

[Business Internet](https://www.g2.com/products/business-internet/reviews) **Product Description:** SpectrumVoIP delivers business internet connectivity for companies that need a reliable, professionally managed connection to support VoIP, video conferencing, cloud applications, and day-to-day business operations. In the Dallas-Fort Worth metroplex and El Paso, SpectrumVoIP operates its own fixed point wireless network, delivering speeds up to 500 Mbps. Because fixed wireless runs on a separate network path from cable and fiber infrastructure, it functions as genuine redundancy rather than a secondary connection that shares the same underlying lines. This makes it a strong choice as either a primary or backup internet solution for businesses that cannot afford downtime. Outside those markets, SpectrumVoIP works with a national network of ISP partners to source shared fiber, dedicated fiber, or coax connections based on the business's location, bandwidth requirements, and budget. SpectrumVoIP handles ISP procurement and coordination, which typically results in better pricing than businesses can negotiate on their own. Internet service can be bundled with SpectrumVoIP's VoIP phone system for a combined monthly rate, a single support contact, and a network configured from the start to prioritize voice traffic quality. Add-ons include Wi-Fi access points and cellular failover for additional redundancy. ### 4.

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.

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.

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?

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.

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. ### Software and services related to VoIP software - [Audio conferencing software:](https://www.g2.com/categories/audio-conferencing) Audio conferencing software uses a hosted voice connection for communication.
