'ZDNET Recommends': What exactly does it mean?
ZDNET's recommendations are based on many hours of testing, research, and comparison shopping. We gather data from the best available sources, including vendor and retailer listings as well as other relevant and independent reviews sites. And we pore over customer reviews to find out what matters to real people who already own and use the products and services we’re assessing.
When you click through from our site to a retailer and buy a product or service, we may earn affiliate commissions. This helps support our work, but does not affect what we cover or how, and it does not affect the price you pay. Neither ZDNET nor the author are compensated for these independent reviews. Indeed, we follow strict guidelines that ensure our editorial content is never influenced by advertisers.
ZDNET's editorial team writes on behalf of you, our reader. Our goal is to deliver the most accurate information and the most knowledgeable advice possible in order to help you make smarter buying decisions on tech gear and a wide array of products and services. Our editors thoroughly review and fact-check every article to ensure that our content meets the highest standards. If we have made an error or published misleading information, we will correct or clarify the article. If you see inaccuracies in our content, please report the mistake via

Voice over Internet Protocol (
VoIP
) phone systems have become a crucial part of modern business infrastructure for handling communication between companies, clients, and customers. VoIP might sound like it's just for audio and calls, but in 2026, these providers offer everything from calls and video conferencing to smart routing, collaborative work tools, AI, messaging, transcription, and even analytics, all of which might be compatible with existing CRMs and SaaS solutions.

Before you choose your new VoIP service, explore whether you want a cloud-based or on-premise solution, your budget, scalability, and whether you want advanced features. These are the best providers on the market that combine business VoIP communication tools, innovative features, scalability, and value for money.
In ZDNET's April update, we conducted an overhaul of our guide and FAQs. We also included Zoom Phone as one of our top picks and moved 8x8 to our alternatives, as we prefer Zoom's approach to transparency and pricing.
