Internet protocol private branch exchange

(also IP PBX)

Internet protocol private branch exchange definition

The internet protocol private branch exchange (IP PBX) is a telecommunication system. Businesses use it to manage phone calls over the internet, unlike traditional PBX systems that use analog or digital signal lines. IP PBX converts voice data into packets and sends them through IP networks. It’s an internal system, but by using VoIP gateways, calls can be made outside the network.

Advantages of using IP PBX

It significantly reduces spending for phone services, especially for long-distance or international calls.

  • It’s easy to scale depending on the company’s needs, and no major hardware changes are needed.

  • Remote employees can also use it from any location.

Disadvantages of using IP PBX

  • The quality and stability of the calls will be highly dependent on the quality of the company’s internet connection.
  • Initial setup will be pricey compared to traditional systems, but the long-term savings should offset it.
