What is small business VoIP?

Small business VoIP is essentially a business VoIP phone system that enables companies to make and receive calls, chat with teams, message customers, and even host video meetings through the internet using a mobile or desktop app. Unlike traditional landlines, it doesn’t require costly hardware or dedicated desk phones, helping small businesses cut communication costs significantly.
And that's only the beginning.
Leading business VoIP solutions like Yeastar P-Series include advanced features at no extra costs, such as auto-attendants, text messaging, business voicemail, call center, and integrations with Microsoft Teams, Outlook, and WhatsApp. With the best VoIP for small business, your teams can easily connect with customers on different devices.
How does business VoIP work for small businesses?
Business VoIP (Voice over Internet Protocol) works by turning your voice into data (also called data packets). Your digital voice data are then transmitted over the internet. To enable VoIP calls, companies typically need a VoIP phone system (also known as PBX) and a VoIP phone line (also called SIP trunk or virtual phone line).
For small businesses, this means you can make and receive calls on desk phones, mobile apps, or web browsers—all connected to the same VoIP platform. Beyond voice, modern business VoIP also enables video meetings, instant messaging, voicemail-to-email, and integrations with CRM or collaboration tools.
