ABSTRACT:
A method and apparatus for connecting a manager terminal to an IP PBX system includes receiving a link request signal from the manager terminal via a connection line, switching the link request signal to a central control unit if the link request signal includes appropriate identification information, and activating a predetermined protocol to provide an Internet environment to the manager terminal in response to the link request signal. The connection line between the manager terminal and the IP PBX system is preferably either a single line telephone (SLT) network or an SLT line connected to a public switched telephone network (PSTN). The identification information in the line request signal may be a telephone number from which the manager terminal is communicating or another telephone number. A password authentication procedure may also be implemented to confirm the identify of the manager who sent the link request signal. Through this method and apparatus, a manager may establish a connection to the IP PBX system to control that system using a management program regardless of the manager's location and without the use of a local area network. This results in significant cost savings and convenience to the manager and IP PBX system owner.
