IP PBX is a hybrid phone system that combines the reliability of a PBX with the cost-effectiveness and customization of VoIP. It is generally considered by businesses to be quite easy to manage and has the ability to smoothly operate over a standard PSTN (Public Switched Telephone Network.)

PBX

A traditional PBX system is located at the company that it services. It manages and transfers calls through a telephony or circuit switched network and consists of a physical telephone exchange and substantial amount of wiring inside the building. PBX’s still maintain popularity with many businesses since they are known to be quite dependable. They tend to have a high quality of service, which can be very important for companies seeking to project a professional image to the public. The PBX can also automatically determine the outgoing line for a phone call.

VoIP

VoIP is a phone service that allows businesses to make and receive phone calls over the internet. It digitizes the audio signal, encrypts it to ensure security, and transmits the phone call across a packet-switched network. This can save a business a great deal of money since they just pay a monthly fee to the hosting company and don't have to spend as much on setup and infrastructure. There is also a great deal of flexibility and customization available with VoIP, since it can be scaled up or down as needed, and the phone can switch locations simply by unplugging it from one port and connecting it to another. Other benefits of VoIP include features like videoconferencing, automatic redial, selective call rejection, and advanced call distribution.

IP PBX

IP PBX manages to take the best parts of PBX and VoIP and combine them into one quality phone system. They have the telephony device of a traditional PBX along with a network adapter that supports internet protocol, and this hybrid system allows them to connect digital telephones and classic analog devices.

The physical hardware of the IP PBX can be reassuring for businesses. It serves as a dependable means to manage phone calls and communicate with customers. It also provides access to a phone network that still works during power outages, which is not always the case with VoIP systems. In addition, there is increased reliability for 911 calls since a physical line is available. The company will still have the ability to make phone calls over the internet, however. IP PBX provides the same services as VoIP, so the company can save money on long distance calls, conference calls, and operational costs. The previously described special features like advanced call distribution are also available through IP PBX and tend to be just as easy to implement.

It can be difficult for a business to decide which phone system to switch to. They each have their own benefits and represent a long term investment for the company. With IP PBX, there is the opportunity to get the best of both worlds and have a phone system that can truly help a modern business to thrive.
