     "description": "Private Branch Exchange (PBX) is actually a type of telephone system that has got all the features of a larger, more complex system. Through centralized control a PBX provides inexpensive and rapid switching of calls to different departments, individual extensions or trunks. A PBX also controls numerous lines to enhance your flexibility by transferring calls and messages internally and externally. In other words, it serves as an intercom system for the entire organization.
