What is a PBX phone system?

PBX Phone System (PBX) stands for Private Branch Exchange, which is a private telephone network used to manage incoming and outgoing phone calls and allows  internal communication between extensions within a business.

A PBX phone system is made up of both hardware and software and connects to communication devices like telephone adapters, hubs, switches, routers and telephone sets.

Traditional PBX

Traditional digital or analogue PBX phone systems would be installed on business premises depending on the number of users which would determine the number of ports needed (one per user) it could be in the airing cupboard, a small computer room or even a very large computer room with racks and racks of hardware.

The overall costs of this type of PBX system could be very high due to scaling and costs calculated per employee.

These traditional PBX systems are complex and bespoke and requires a manufacturer certified engineer to, install and fix any issues so the cost of higher.

Many businesses still prefers to operate on traditional PBX phone systems managed by their with their own in-house IT, giving them full control and ownership of the hardware unlike in other PBX solutions.

Telephony has advanced significantly over recent years, the trouble with installing a traditional or analogue PBX system is that it starts losing value as soon as it goes on the wall.

VoIP/IP PBX

IP PBX system also known as a VOIP system (Voice over IP) and delivers voice or video over a data connection. PBX has changed a lot with the advent of IP telephony or VoIP.

The analog PBX worked only on the telephone line and switches, we now have IP-PBX, which use VoIP technology and IP networks like the Internet to channel calls.

The VoIP PBX convert the voice into data and transfer it across the network as packets.  Using data networks for voice will significantly reduce the cost of long distance, international calls and reduce the overheads of traditional line rentals.

Some traditional PBX solution can support SIP trunk, most business PBX are IP enabled.

IP PBX are today’s preferred choice due to the features that they come with.  Except for legacy but still-working PBX, and those chosen because they are cheap, most PBX systems installed nowadays tend to be IP PBX.

An IP PBX can also switch calls between VoIP and traditional telephones while still offering the  same legacy PBX phone system functionally. VoIP/IP PBX differs from a hosted or cloud based solution as the IP PBX is owned by the business, just as with a traditional PBX.
