A cloud business phone system (also called a VoIP phone system or hosted PBX) is a modern communication solution that allows businesses to make and receive calls over the internet instead of traditional phone lines. Unlike legacy landline systems, cloud-based phones operate entirely online, offering greater flexibility, scalability, and advanced features at a lower cost.
This guide explains how cloud phone systems work, their key benefits, top providers, and how to choose the right one for your business.
How Does a Cloud Phone System Work?
A cloud phone system uses Voice over Internet bosnia and herzegovina phone number list Protocol (VoIP) to transmit calls as data over the internet. Here’s how it functions:
Internet Connection Required – Calls are routed through broadband instead of copper wires.
Hosted in the Cloud – No on-site hardware (like a traditional PBX box); everything is managed by the provider.
Accessible from Any Device – Employees can use desk phones, smartphones, or computers to make calls.
Scalable & Flexible – Easily add or remove lines as your business grows.
Key Components:
VoIP Phones – Physical handsets designed for internet calls (e.g., Poly, Yealink).
Softphones – Apps (like Zoom Phone, Microsoft Teams) for calling via computer/mobile.
Virtual PBX – Cloud-based call management (auto-attendant, call routing).
SIP Trunking – Connects your system to the public phone network (PSTN).
