Service registration method and equipment

Abstract

The invention discloses a service registration method and service registration equipment. The method comprises that: after receiving a voice over Internet protocol (VoIP) service registration request from an Internet protocol (IP) telephone, a VoIP server registers a corresponding service of the IP telephone according to a VoIP service feature code in the request; the VoIP server searches for a public switched telephone network (PSTN) service feature code corresponding to the VoIP service feature code and an IP address of a VoIP gateway corresponding to the IP telephone; and the VoIP server transmits a PSTN service registration request of the IP telephone to the VoIP gateway according to the found PSTN service feature code and the found IP address to make the VoIP gateway register the service of the IP telephone to a private branch exchange. By the method and the equipment, the service of the IP telephone is registered on the VoIP server and the private branch exchange respectively.

Description

technical field [0001] The invention relates to the communication field, in particular to a service registration method and equipment. Background technique [0002] Examples of traditional telephone networks are figure 1 As shown, including analog phone A, PSTN (Public Switched Telephone Network, public switched telephone network), PBX (Private Branch Exchange, program-controlled exchange) and analog phone B, C, the call initiated by A is connected to B or C through PBX to establish and A call between B or C. [0003] VoIP (Voice Over Internet Protocol, Voice over IP) technology transforms the traditional telephone network 1:1, connects the program-controlled switchboard to the subscriber line of the analog telephone set, and connects it to the trunk interface of the VoIP gateway, such as FXO (Foreign Exchange Office, external exchange Office) interface, the FXO interface is bound to the IP phone. The following trunk interface uses the FXO interface as an example for illu...

Problems solved by technology

At the same time, if phone B forwards the call to the PSTN number, the same as Figure 4 The process shown is similar, but FXO-B will still be occupied, and the use of relay resources is unreasonable

The cause of this problem is: Figure 4 Among them, the call forwarding service of IP phone B is only registered in the VoIP Server, and the call forwarding service of phone B is only executed by the VoIP Server. The program-controlled exchange cannot know the changes of the IP phone, so it cannot adjust the occupancy of the FXO interface accordingly.
