System and method for converged communication Internet protocol (IP) - private branch exchange (PBX) internal and external network interconnection

Abstract

The invention relates to a system and a method for converged communication Internet protocol (IP) - private branch exchange (PBX) internal and external network interconnection. An in-enterprise converged communication system is arranged in an enterprise internal network, external network converged communication is arranged at the cloud end, internal and external network converged communication servers are connected in a relay mode through a session initiation protocol (SIP), due to the fact that communication is in a local area network, communication voice quality in an enterprise can be guaranteed reliably. In order to achieve voice communication between internal network staff and Internet staff or staff of other enterprises, voice stream intercommunication between internal and external network converged communication systems is achieved, two network cards are mounted on an external network server, one of the network cards is connected with an internal network, the other network card is connected with an external network, an external network converged communication process monitors the external network card, data sent to the external network from the internal network is received by the internal network card first and then transferred to the external network card, an external network converged communication service process receives and processes the data, data sent to the internal network from the external network is routed to the internal network card, an internal network converged communication service process receives and processes the data, and therefore intercommunication of call instructions and voice streams between the internal network and the external network is achieved.

Description

technical field [0001] The present invention relates to a converged communication technology, in particular to a system and method for interconnecting internal and external networks of a converged communication system. Background technique [0002] As an enterprise communication technology that replaces traditional PBX, converged communication is widely deployed on enterprise intranets; social software mainly serves the society and must be deployed on public networks. With the popularization of smart phones and the increasing demand for mobile office, converged communication services urgently need to be extended to mobile communication networks and the Internet, which can greatly facilitate communication among employees within the enterprise, without the need to deploy a VPN network, no matter where employees travel, Whether you are traveling, in a hotel, or at the user site, you can use notebooks, smartphones, and tablets to communicate with colleagues and partners anytime,...
