What is a PBX Phone System?
PBX stands for Private Branch Exchange, which is a private telephone network used within a business. The users of this PBX share a number of outside lines capable of making external phone calls – these phone calls are carried out of the public switched telephone network (PSTN).
PBX phone systems used to only be reserved for large enterprises, but over the years the prices in installation and running costs have been reduced significantly; which means any business can now invest in an office phone system.
Features of PBX phone systems include; welcome messages, call holding, call conferencing, automatic call distribution, a directory of extension numbers and archiving of call records. There are many other features available depending upon the type of system you invest in and if you require and third party plugins.
There are three main types of PBX systems.
- Traditional PBX/Analogue PBX
Traditional PBX or analogue phone systems exist as a physical exchange box on your company’s premises. The overall costs of this type of PBX system may seem higher than other systems, but due to scaling and costs calculated per employee the price actually decreases with the number of ports required.
Here, a phone box is used that connects all the on-site phone lines (ISDN lines), the costs are usually higher due to installation, down time and maintenance and support. As traditional PBX systems tend to be more complex and bespoke it requires a certified engineer to fix any issues.
Many businesses prefer to operate on traditional PBX phone systems with their own in-house overheads. Usually this is in the form of a comms room that is looked after by your IT team, it also gives you full ownership of the hardware unlike in other PBX solutions. For companies operating out of one building, the PBX phone system can be just as beneficial as a virtual system.
