Since IP PBX uses the SIP(session initiation protocol) trunking process, this application layer can be used to operate a telephone service over the internet and connect phone systems. All you need to do is set up your SIP trunk with a provider and create a small physical space for data pockets for storing call data.

IP PBX uses a cloud platform, so it is flexible and scalable compared to traditional PBX so that you can connect with employees and customers from anywhere. Apart from flexibility, the cloud PBX system offers a wider range of features like unified communications, video calling, SMS, conferencing calls, call recording, and more at a very affordable rate and without any high infrastructure cost.

How Does a PBX Phone System Work?

A private branch exchange (PBX) phone system is a telecommunications network used by organizations to facilitate internal and external communication. PBX works by operating as a private switchboard, connecting multiple internal phone lines and allowing users to make phone calls within the organization without requiring an external line.

Furthermore, the PBX system manages incoming and outgoing calls by routing them to the appropriate extension. Internally, when this phone system receives a call, it helps to guide calls, enabling features like call forwarding, transfer, routing voicemail, and conference calling. To connect calls to external numbers, it interfaces with the public switched telephone network (PSTN).  PBX system uses predefined rules, like IVR menus or time-based routing, to route calls. PBX flawlessly handles outbound calls by connecting them through available phone lines or service providers.

Modern PBX systems utilize Voice over Internet Protocol (VoIP) technology for cost-effective, flexible communication, better call handling, and an abundance of the latest call management features.
