What do IP-PBX and VoIP mean?

The full name of PBX is Private Branch Exchange, which is simply a group telephone and is widely used in corporate offices. Traditional PBX has many problems and is very expensive. In recent years, with the popularity of the Internet and the success of IP, IP-PBX based on the IP protocol has emerged. You can usually see many writing methods, such as IPPBX, IP PBX, ippbx, all expressing the same meaning. IP-PBX is an IP-based corporate phone system that integrates voice communications into a company's data network, creating a unified voice and data network that connects office locations and employees around the world. The most significant feature of IP-PBX is that it has become an integrated communication system. Through the telecommunications network and the Internet, only a single device is needed to provide users with multiple communication methods such as voice, fax, data and video. Small and medium-sized call centers can also be established at low cost. Through full integration with network software and hardware, work efficiency is improved and communication costs are saved (saving time and money). Shanghai Xunshi OM80E is an IP-PBX for enterprises with less than 200 people. It integrates voice, mobile office, and open interconnection, and provides a variety of integrated communication solutions for office buildings, hotels, electric power and other industries.
