PABX Telephone System, How does it work?

The term PBX stands for Private Branch eXchange. A PBX, sometimes known as a phone switch or phone switching device, is a device that connects office telephones in a business with the public telephone network. The initial central functions of a PBX were to route incoming calls to the appropriate extension in an office, and to share phone lines between extensions. Over time, many functions have been added, such as automated greetings for callers using recorded messages, dialing menus, connections to voicemail, automatic call distribution (ACD), teleconferencing, and more.

The hardest feature to provide has been Automatic Call Distribution (ACD), and usually vendors charge a premium for products that include this feature. Other features that often get left out include integrated voice messaging, conference bridging for conferencing multiple outside calls, and detailed real-time system monitoring. Many times some of these features are not part of the base PBX system but can be purchased through add-on system modules.

so basically the cost will escalate depending on the number of modules that you require for your solution.
