IPPBX integrated with 2G, PSTN and VOIP accesses

Abstract

The invention relates to an IPPBX system integrated with 2G, PSTN and VOIP accesses, which consists of a main control module, a GSM module, a POTS / FXS module, an FXO module and an Ethernet switching module, the GSM module, the FXO module and the POTS / FXS module are communicated with the main control module through a TDM mode, the main control module is connected with the Ethernet switching module through an Ethernet, wherein the GSM module accesses a 2G network, the FXO module accesses a PSTN network, a POTS / FXS module accesses a telephone intranet, the Ethernet accesses the main control module via the Ethernet switching module, consequently, data exchange is realized between voices coming from different channels, and 2G, PSTN and VOIP accesses are integrated. The advantages of the invention are as follows: the current various mainstream voice access modes are integrated into the same IPPBX equipment, moreover, each two accesses do not depend on other access modes, meanwhile, when the system is adopted, networking is simple, and the investment cost and maintenance cost of equipment are greatly reduced.

Description

【Technical field】 [0001] The invention relates to an IPPBX (IP-based company telephone system) equipment for integrated voice access, in particular to an IPPBX integrating 2G, PSTN, and VOIP access. 【Background technique】 [0002] With the development of IP (Internet Protocol) technology and softswitch technology, IPPBX has been applied by more and more enterprises. In the current converged application environment, IPPBX integrates VOIP (Voice over IP, transmitting analog audio or video on the IP network) and PBX (Private Branch eXchange, user-level exchange) technologies, and realizes integration with PSTN ( Convergence of the Public Switched Telephone Network). The IPPBX telephone exchange system realizes the integration of the functions of the computer network and the telephone exchange. The telephones in the network use the IP method for data communication, especially in the long-distance collaborative office. Come conveniently. [0003] With the help of the global ne...

Problems solved by technology

figure 1 The IPPBX in , needs external equipment, namely figure 1 The VOIP gateway and the landing gateway in the network can realize the integration of VOIP, PSTN and 2G networks. Even if there is no access to the PSTN network, the access from VOIP to the 2G network cannot be realized, and the two-by-two connection between VOIP and 2G networks cannot be achieved. Fusion, with certain limitations

At the same time, the equipment required for networking increases, and the dependence on the telecom PSTN is also particularly large. However, the product is not flexible enough in actual application and cannot meet the diversified needs of customers.
