What is IP PBX?

PBX, which stands for Private Branch Exchange, is a telephone system used within an organization to manage incoming and outgoing calls, as well as internal communication.

IP PBX, as its name indicates, is a variant of a PBX that can make and receive calls through internet connections instead of using physical landlines. An IP PBX System enables multiple users to utilize a single set of phone lines, efficiently directing calls among VoIP-enabled individuals.

Compared with traditional PBX, IP PBX offers greater flexibility, scalability, and feature-rich capabilities. It helps reduce costs, enable seamless integration with various communication tools, and increase efficiency.

Types of IP PBX Systems

Choose between two types of IP PBX options based on your specific needs.

1. On-premise IP PBX

An on-premise IP PBX is a phone system that businesses install and operate on their own premises. This setup grants businesses complete control over their phone system, offering reliability, stability, and enhanced system security.


2. Cloud-based IP PBX

A cloud-based IP PBX or hosted PBX, is a virtual phone system hosted off-site, typically by a third-party service provider. Users access the PBX features through the internet, making and receiving calls via their devices.
