Table of Content

There are multiple factors to consider when selecting a telephone system, such as its size, scope, features, functionality, interoperability, maintenance reliability, and upgradeability. Additionally, cost and vendor selection are essential in determining the most suitable system for the company’s needs.

Future advancements necessitate compatibility with different systems, such as voice mail and electronic messaging systems, PCs, LANs, video and multimedia servers, and wireless systems.

A PBX, also known as a private branch exchange, is a telephone system used within a company. Its primary function is to connect calls between employees using local lines, while also allowing the company to have a specific number of external phone lines. By using a PBX, the company can avoid the expense of having a separate line for each employee connected to the telephone company’s central office. Unlike in the past when a live operator was required, most PBXs today are automatic. Therefore, the terms PBX and PABX (private automatic branch exchange) are interchangeable.

Today, PBXs utilize digital technology, which is made possible by their evolution through four generations. The initial generation relied on analog technology and had limited features and technology. The second generation introduced stored-program control processors, while the third generation was the first to support end-to-end digital transmission and utilized both digital and analog proprietary telephones. The fourth generation lacks a clear definition but incorporates LAN interfaces to establish a pathway for connecting data devices.

  • Telephone trunk lines that terminate at the PBX.
  • A computer with memory that manages the switching of the calls within the PBX and in and out of it.
  • The network of lines within the PBX.
  • Usually, a console or switchboard for a human operator.

Many medium sized or larger companies implement a PBX system for its cost-effectiveness compared to connecting an external telephone line to every phone set within the organization. Additionally, communicating within a PBX is simplified as the required dialing number is usually only 3 to 4 digits.

The chosen PBX system is the Bizfon 680. It allows for the use of remote phones, like cell phones, as if they were directly connected to the Bizfon system. This is made possible through the unique Universal Extension feature. By dialing your extension number, anyone can be automatically connected to your cell phone. Additionally, you can access and control all of the Bizfon’s features using your cell phone or any other remote telephone. This includes using outside lines, ensuring that all business-related calls are charged to your office account.
