Abstract

This invention discloses a method for realizing extension roam of group users by the set of phone flows including a roam flow, a called flow and a calling flow, in which, the extension users set roam information of roam numbers and switch stragetegy by phone flows, when the roam extension user is called, a service control module selects suitable numbers to start up the call based on the user roam information set in the service data module, when the roam extension is the calling user, the service control module inquires the service data module based on the calling number to process said calling as the extension in the group, in which, users can set multiple roam numbers at the same time and set switch strategy conveniently.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a method for group user extension roaming based on a virtual switchboard.

Therefore, how to further consolidate and develop their own group customer groups and business markets is the focus of great attention of major telecom operators. The current group customer services mainly include private branch exchange PBX services and virtual private network services based on intelligent network technology.

Problems solved by technology

[0005] 1. The extension of the PBX system is a fixed extension, which is suitable for a fixed office environment, but cannot be moved or roamed, and cannot meet the requirements of modern mobile office;

[0006] 2. With the help of the mobile switching network, the VPN service can provide mobile call services for mobile phone users of GSM and CDMA networks, but cannot provide mobile call services for PSTN fixed network users;

[0007] 3. The short number of the VPN service extension corresponds to the long number of the user. At present, it can only be modified through the business hall, and cannot be dynamically set, so it is not flexible enough. Although the user can use the call transfer function provided by the switching network to partially solve the problem of receiving calls. problem, but the setting method is single. You can only use the machine to dial a special number to set or cancel when the network supports it. At the same time, you cannot choose according to the status of the user's phone

[0008] 4. When the extension of a group user is called, the call cannot be transferred to a phone other than the group user to answer; when the extension of the group user is the calling party, the phone other than the group user cannot be used to call other extensions in the group, and the effect is equivalent to using The extension dialed directly
