An IP PBX is a private branch exchange (telephone switching system within an enterprise) that switches calls between VoIP (voice over Internet Protocol or IP) users on local lines while allowing all users to share a certain number of external phone lines. The typical IP PBX can also switch calls between a VoIP user and a traditional telephone user, or between two traditional telephone users in the same way that a conventional PBX does. The Early generation of PBX needs analog lines to operate and more complicated to set up. IP PBX allows the user to enjoy PBX features through IP networks. There is also hybrid PBX that can handle analog lines for the incoming lines, and route the line through VOIP. (source)

Why IP PBX?
Conventional PBX require separate networks for voice and data communications. With a conventional PBX, separate networks are necessary for voice and data communications. IP PBX allows single networks for voice and data communications. Because of this, companies can save on subscription and also for expansion as to add new extension or line, it can be done with low or no additional cost.
What are the benefits of IP PBX?
- Easier to manage because of GUI based interface
Traditional PBX requires the programming/setup to be done on the physical phone. With IP PBX, the GUI helps user to setup the phone. User has more possibility to setup themselves rather hiring professional to do the changes.
- Eliminate phone wiring
With IP PBX, different type of phone, such as IP Phone are able to be connected to the machine. rather than setting up new wiring from the PBX to the actual location of the phone, IP Phone can tap on LAN connection to be registered to the PBX.
- Combine data and telephony cost.
Instead of subscribing 2 separate subscriptions, you can just subscribe to data plan subscription.
- Allow to make and receive call anywhere
IP PBX allows connection externally. As long as you have connection and access to your office intranet, you can connect SIP phone from outside office network. So you can receive and make call as if you’re in office.
- Allow hot desking
- Lower operational cost over time (save on your phone bill especially on IDD call)
IP PBX can handle different type of phone connection. The user has the flexibility to use a normal analog line, VOIP trunk (or SIP Trunk Line), ISDN, etc. with lower IDD call rates, you can minimize the cost of your phone bill.
