What is PBX System?

Integrated business phone system that businesses use to communicate with each other in the organization.

A PBX system is an integrated business phone system that businesses use to communicate with each other in the organization and with an outside audience. PBX is an acronym for Private Branch Exchange and typically uses Voice over Internet Protocol (VoIP) technology to control inbound and outbound call flows.

The term Private Branch Exchange has its roots in the call switchboards used in the old days, where call switching on the correct line and extension used to be done manually by operators. As the technology started to evolve, the switchboards were replaced by machines but the concept remained the same.

PBX is getting more and more popular due to its next-generation features and flexibility that it offers. Unlike the traditional PBX phone systems, which used open standards, modern PBX phone solutions use robust hardware that can be easily replaced and is cheaper than others.

Some vendors might also provide you API access with which you can create custom solutions and integrate the same into your business processes.
