About PBX
What is a PBX?

PBX, which stands for Private Branch Exchange, refers to the internal communications network system at an office. This is where a multiline phone connection is attached to a telephone trunk.

Now there are many organizations that are transitioning to a full-fledge PBX system but there are some that want to merge it with cloud function.  This combination of PBX backed by cloud functionality is known as a Hybrid PBX.

1. Conventional PBX

A PBX or PABX (Private Automatic Branch Exchange) system is an automatic telephone switching system within enterprises. A PBX system allows a single access number to allow multiple lines to outside callers. Conventionally the PBX system is hosted within the enterprise.

  • A conventional PBX will need separate networks for voice and data
  • A conventional PBX offers reduced flexibility
  • A conventional PBX must be owned by the enterprise and situated on the premises.
  • A conventional PBX is expensive.

2. Virtual PBX

A Virtual PBX on the other hand is a scaled-down version of a Conventional or Hosted PBX system and generally only handles inbound calls. It is owned and maintained off site by a VOIP (Voice over IP) service provider much like a conventional PBX however it is geared toward simple inbound call-routing for SoHo offices with few staff, smaller budgets, and simple calling needs.

Read our article Advantages of a Virtual PBX for full information on why this system is so beneficial. We have however highlighted a few points below:

  • A Virtual PBX uses converged data and voice networks; this means that communication is possible using a single line (for voice and data) to each user.
  • A Virtual PBX provides increased flexibility
  • A Virtual PBX is hosted offsite at the service provider
  • A Virtual PBX has lower operational and maintenance costs

Hybrid PBX

A Hybrid PBX is a conventional PBX, which mostly uses traditional analogue or digital phone networks, but which has been expanded (usually by plugging in an additional card) to allow it to communicate using the SIP IP-protocol. This allows it to connect to IP phones or to a remote IP system.

  • An important feature of the Hybrid PBX is that if either the conventional PBX or VOIP server isn’t working, it will automatically switch over to the other network.
  • A Hybrid PBX is excellent for remote offices and secondary locations.
  • A Hybrid PBX is more costly than a Virtual PBX
  • A Hybrid PBX has to be owned by the enterprise and situated on the premises.
  • A Hybrid PBX allows for easy transition to full VOIP and Hosted PBX solution.
