IP PBX is a multifunctional telephone system that switches voice and video calls over an IP network. Voice and video are transmitted as a data stream (IP packets). Along with advanced communication technologies, IP PBX offers excellent resource scalability and increased reliability.
Connection to the usual analog telephone, digital or GSM lines is possible with the help of optional inexpensive VoIP gateways, so the transition from an outdated ATS to modern corporate communications will not cause any special difficulties.
Companies do not even have to interrupt the provision of telephone services - IP PBX is deployed in parallel with the existing station. At some point, when everything is connected and tested, existing telephone lines simply switch to new IP gateways. The company retains its old, known numbers, and IP gateways convert voice from other technologies into IP packets with which IP PBX works.
