Stability Hybrid Intercom Telephone System for Hotel PBX

Another development trend is the concept of core functions. PBX service has always been difficult for some small companies, because many companies believe that solving the problem of telephone is not the core function of the company itself. These considerations have led to the emergence of the concept of hosted PBX. For the installation of hosted PBX, PBX is installed at the telephone supplier and managed by the supplier. All functions and calls are transmitted through the Internet. What customers need is simply signing a service contract, rather than purchasing and maintaining expensive equipment.

During the 1990s, due to two significant developments, a new type of PBX system emerged. One is the rapid expansion of data networks and the widespread acceptance of packet switching by the public. Enterprise companies need data packet switching network. The prospect of using this network for telephone exchange is attractive. In addition, the wide use of the Internet as a global data switching system makes packet switching communication more attractive. All these factors contributed to the development of VoIP PBX.
