What is PBX?

If you’ve ever transferred a call or had your call transferred to another party, chances are you’ve experienced the use of a PBX. PBX (short for private branch exchange) is a telephone system that allows your company to connect all your internal phones to external telephone lines in the same network. This way, you can lease only one line and have many people using it by assigning each person a phone with a short unique extension number. Moreover, anyone on the system is able to call and transfer calls to other extensions. Unfortunately, traditional PBX systems can be quite expensive since it requires a capital investment to purchase, install and maintain your own telephony system.
