Private Automatic Branch Exchange (PABX): an automatic system for managing calls between different phone numbers in a particular business or offices, as well as calls to and from numbers outside the business.

 

The PABX provides management of the channels on the link enabling fixed bandwidths to be allocated to specific users.

 

Time and technology, however, have changed the consumer telephony landscape, with the flag-bearer being the Open-Standards-based IP PBX. The point of the “IP” in this new era is that the phone calls are delivered using the Internet Protocol as the underlying transport technology.

 

PBX phone systems are available as hosted or virtual solutions and as on-premise solutions to be run on your own hardware.

Switching to an IP PBX brings with it many benefits and opens up possibilities, allowing for almost unlimited growth in terms of extensions and trunks, and introducing more complex functions that are more costly and difficult to implement with a traditional PBX, such as:

  • Ring Groups
  • Queues
  • Digital Receptionists
  • Voicemail
  • Reporting
  • Intercom / Paging
