Abstract
Description
technical field
[0001] The invention relates to a communication control and information security technology, in particular to a system and method for realizing a call authentication gateway. Specifically, on the premise of not needing to modify the existing network equipment, call authentication is implemented independently, so as to achieve the purpose of standardizing the calling number and restricting illegal calls in real time. Background technique
[0002] In order to ensure smooth communication between networks, it is necessary to standardize the calling number and restrict unreasonable calls in real time.
