PBX Tutorial

Phone systems have evolved drastically in the last 40 years. It used to be that the only way to get multiple lines into a location was to have the phone company install them individually. When Centrex systems came along, interoperability between lines, along with intercom functions, became available.

Then, a whole new world opened up when PBX systems came on the scene. PBX stands for Private Branch Exchange. This allows an organization to have multiple lines that are completely functional and with features, such as voice mail, and more.

How PBX Works

There are two types of PBX systems. First is an on-site system which resides inside of a customer facility and is owned and managed by the provider company. The second is a hosted PBX system which is owned and operated off-site by a separate company or provider.

The hosted PBX systems use technology called VoIP (Voice over Internet Protocol). This allows a hosting company to provide advanced off-site services which were only available to on-site systems before now.

The phone company, or Telco as they are also known, supplies the phone lines to your building. The PBX system takes those lines and converts them into digital information that allows for a total and complete configuration to meet a company’s varied voice communication needs.

What is Included in PBX Services?

The original purpose for a PBX was to save money, but that has become less common because of the variety of services now offered.

Some of the important services that are provide by a PBX system include: individual voice mail boxes; call forwarding; call hunt groups; call routing; extensive call menu systems; conferencing; call following; and more.

These services allow for greater ability to meet the needs of customers and prospects by offering a host of contact options.

The Future

There is a convergence of communications companies already being developed. Telephone companies will no longer supply just phone services. More and more, phone companies are adding other services including, Internet access, mobile phone service, and a host of data services that include entertainment.
