Problems solved by technology

[0003] However, since the call control server is only available in some areas in the entire call system, the call control server needs to process call requests sent by users in different regions. The call request or the call request sent to the public switched telephone network users in other places must carry the region prefix. If the call request sent by the terminal does not carry the region prefix, the call control server cannot determine the geographical location of the user access point, so that Can not find the correct nearest landing gateway, this point is particularly important for the VOIP user calling the public switched telephone network (Public Switched Telephone Network, abbreviated as PSTN) domain special service number, so, for the VOIP user to dial the local public switched telephone network user or It is very time-consuming and labor-intensive for special service numbers

Abstract

The invention provides a VOIP calling method, device and system and relates to the field of communication. By means of the VOIP calling method, device and system, VOIP users can dial more conveniently when making local calls. The method includes the steps of receiving a login request message sent by a terminal, wherein information indicating the current geographic position where the terminal is located is carried in the login request message; determining access information of the current geographic position where the terminal is located according to the information; receiving a calling request sent by the terminal; if region prefixes are not carried in the calling request, determining a grounding gateway according to the access information and calling a called terminal. The VOIP calling method, device and system are used for selecting VOIP grounding gateways.

Description

technical field [0001] The present invention relates to the field of communication, in particular to a method, device and system for IP bearer voice call. Background technique [0002] Voice over IP (Voice over IP, abbreviated as VOIP) was born more than ten years ago. It has penetrated into carrier-level applications in the form of softswitch products, and IP private branch exchange (IP-PBX) The penetration of enterprise voice communication into enterprise voice communication has profoundly affected the way people communicate. And VOIP can be easily accessed in different regions and realize roaming between different regions. [0003] However, since the call control server is only available in some areas in the entire call system, the call control server needs to process call requests sent by users in different regions. The call request or the call request sent to the public switched telephone network users in other places must carry the region prefix. If the call request ...
