Differences Between IP PBX Telephone Switch and PBX Dedicated Switch

IP PBX telephone switch system integrates the functions of a computer network and a telephone switch. Within the IP PBX network system, each telephone terminal uses IP for data communication, enabling not only voice calls but also the transmission of text, data, and images, unifying the telephone network and computer network into a whole for electronic office within the LAN. It will particularly leverage its strong resource advantages in long-distance collaborative business and electronic office, bringing convenience to business cooperation and work restructuring. The control center within the IP PBX LAN can effectively manage the computer network and telephone network based on specific internal and external conditions, achieving resource sharing. IP PBX networks in different regions can achieve long-distance communication, electronic office, and e-commerce via the Internet.

Traditional PBX uses the principle of circuit switching to implement group telephone functions, while IP PBX uses the TCP/IP protocol and the principle of packet switching to achieve the same functions over Ethernet.

PBX (Private Branch Exchange), in short, is a group telephone system widely used in enterprise office environments, greatly improving operational efficiency. However, traditional PBX has several issues: first, it has insufficient support for emerging CTI (Computer Telephony Integration) and VoIP; second, traditional PBX adopts proprietary technology, lacking openness and standardization; and third, it is expensive. In recent years, with the popularity of the Internet and the success of IP, IP PBX based on the IP protocol has emerged, promising to address the shortcomings of traditional PBX.
