How to Compare the Best VoIP Providers & Services

When selecting a VoIP provider, focus on your business’s unique requirements. Consider your budget, team collaboration style, preferred communication channels, call volumes, and primary call destinations.

Next, evaluate features and pricing from potential providers. Key functionalities to consider include call distribution, auto-attendant, caller ID, video conferencing, SMS capabilities, and file sharing options. The chart below offers an overview of essential features and channels across different providers. Use this comparison to identify which service aligns best with your specific business needs.

What Is VoIP?

Voice over Internet Protocol (VoIP) is a modern phone service that transmits your voice as data over the internet rather than through traditional landlines. This technology is particularly versatile because you can use your phone services from any location with an internet connection. These systems are commonly used for:

• Managing incoming and outgoing phone calls in call centers
• Participating in call and video conferencing
• Conducting distance learning sessions
• Providing telehealthcare services
• Keeping in touch with associates, friends, or relatives around the globe

How Do VoIP Services Work?

VoIP technology converts audio from a microphone into data packets and transmits them over the internet to recipients worldwide. When a company subscribes to a VoIP service, its employees use a desktop or browser app connected to the internet. As they speak into the device’s softphone (virtual phone), the app sends audio data to the provider’s servers.

The data then travels through a global network to reach the call recipient. For calls between VoIP numbers, this process occurs entirely over the internet. However, when calling mobile or landline numbers, the VoIP data converts to mobile data (4G or 5G) or a traditional phone signal (PSTN) to complete the connection.

What Is Business VoIP and How Can It Help Your Business?

Business VoIP solutions use the same audio transmission process as regular VoIP but are specifically designed to meet corporate needs. Unlike traditional PBX systems, VoIP offers numerous advantages that can significantly enhance your business operations, including:

• Quick setup
• No hardware maintenance
• Easy scalability
• Diverse communication channels
• Global business presence
• Enhanced internal collaboration
• Improved customer service
• Superior call quality
• Increased agent mobility
• Unified business identity for remote teams

VoIP empowers your team to work more efficiently by integrating AI support and workflow tools into a single application. This versatile platform enables seamless communication with customers across multiple channels, accessible from any device with an internet or cellular connection. By adopting a VoIP system, your business can streamline communications, reduce costs, and improve overall productivity.

How to Choose the Best Business VoIP Services

It’s essential to take your time to compare VoIP providers. Understanding your specific business needs and how each provider’s features align with your company can make a significant difference in pricing and quality.

Here’s how to choose the right VoIP service for your business:

1. Consider your company’s needs: Determine your budget, desired features, preferred communication channels, degree of collaboration required by agents, and the geographical areas where you frequently operate.
2. Compare collaboration and multichannel features: Look at what communication channels are offered by each provider in our list. Pay attention to their pricing plans, collaboration features of video meetings and team chat, and additional agent-support tools like live call transcription or speech coaching.
3. Assess unlimited calling areas: Review your call logs and volume to determine the destinations your agents call most often. If they make frequent international calls, opt for providers with cheap international rates or multi-country unlimited calling areas.
4. Determine your desired geographical presence: Consider where your customers are and decide if you want to expand your reach in those areas. Look for a service provider that offers DID virtual numbers in the regions where you want to establish a local presence.
5. Compare routing and queueing capabilities: Assess the size of your call center, including the number of agents, supervisors, and departments you have. Determine if you need to route inbound calls to multiple departments like sales. Then, consider routing and queueing features like ring groups, auto attendant menus, skills-based routing, and live queue analytics for supervisors.
