Thanks to advances in technology and digitalisation, mechanical analogue systems have evolved into fully digitalised systems. Modern telephone systems use Voice over IP telephony (VoIP) and provide IP-based, analogue or digital connector ports for a wide range of devices. Devices can be connected to the TC system via a cable or by wireless means such as DECT or WiFi. Thanks to IP telephone systems, voice and data networks and their uses can merge to become one.
Cloud telephone systems store the function of a telephone system in the network, and make local hardware for transmitting telephone conversations redundant. All that is required is a local internet connection with corresponding bandwidth. The maximum number of simultaneous conversations is, in theory, only dependent on the bandwidth of the particular internet connection. Users can access this system through a web browser and configure their requirements accordingly. A significant advantage of cloud systems is their flexible capacity for expansion. If you wish to connect additional locations or expand the capacity of the switchboard, this process is generally possible wholly through software, with no need for hardware at all.
