Problems solved by technology

In the current network environment, harassing calls emerge in endlessly, largely because VOIP calls are based on the Internet and are point-to-point calls. As long as you know the IP, you can send a large number of INVITE calls to cause harassment.

Embodiment Construction

[0017] In order to describe the technical content of the present invention more clearly, further description will be given below in conjunction with specific embodiments.

[0018] This SIP-based protocol of the present invention realizes the method for non-proxy IP rejecting incoming call function, which comprises the following steps:

[0019] (1) The home gateway receives the INVITE call request, and judges whether the currently configured server is a domain name, and if so, proceeds to step (2); otherwise, proceeds to step (3);

[0020] (1.1) The home gateway receives the INVITE call request;

[0021] (1.2) judge whether the server of current configuration is domain name, if yes, then continue step (2); Otherwise, continue step (3);

[0022] (2) DNS resolution is carried out to the server domain name, and all IP addresses resolved are preserved;

[0023] (3) Judging whether the IP address obtained by DNS resolution is consistent with the source IP address of the INVITE cal...

Abstract

The invention also relates to a method for realizing the non-proxy IP call refusal function based on the SIP protocol, and the method specifically comprises the following steps: (1) the home gateway receives an INVITE call request, judges whether a currently configured server is a domain name or not, and continues the step (2) if the currently configured server is the domain name; Otherwise, continuing the step (3); (2) DNS analysis is carried out on the server domain name, and all analyzed IP addresses are stored; (3) judging whether the IP address obtained by DNS analysis is consistent withthe source IP address of the INVITE call request, and if so, normally accessing the call request; And otherwise, refusing the call request. The method for realizing the non-proxy IP call rejection function based on the SIP protocol can judge Whether the source IP is consistent with the currently configured server or not from the source, it is guaranteed that only the INVITE call request from the self-registered server can be accessed, and therefore inconvenience brought to clients by harassment calls is effectively avoided.

Description

technical field [0001] The invention relates to the technical field of electronic equipment, in particular to the technical field of a home gateway with VOIP function, and specifically refers to a method for realizing the non-proxy IP rejecting incoming call function based on the SIP protocol. Background technique [0002] At present, with the popularization of EPON (Ethernet Passive Optical Network, Ethernet Passive Optical Network) and GPON (Gigabit Passive Optical Network, Gigabit Passive Optical Network) technologies in China, as well as the national technology development strategy of optical advance and copper retreat, Related home gateway products, such as various EPON HGU (Home Gateway Unit, home gateway unit), GPON HGU, etc., are rapidly entering major cities and entering every household. [0003] Due to the popularization and use of these home gateway products carrying VoIP (Voice over Internet Protocol) functions, VoIP technology has been widely used in daily life....
