A PBX can be purchased outright at significant capital investment or, as is the case with TMC Connect, can be hosted for you at a minimal monthly fee. The PBX is made up of users, who either each have their own extension or can share extensions. The number of extensions is flexible. TMC Connect provides sufficient capacity to handle simultaneous calls. Users can have either softphones (accessed by computer or mobile) or a handset. Handsets can be standard to advanced, with displays and multifunction capability, or conference handsets or full featured attendant consoles for more complex business applications.
