A study of global numbering plan with active anti-spit capability on VoIP

The traditional E.164 codepsilas regularity enables the scoundrel to be possible not after the telecommunication userpsilas permission on easily the segment to userpsilas telephone number. It is difficult to meet the VoIP protection needs for using the packet filtering technology with the network-level gatekeeper defense mechanism. This paper proposed a VoIP access authorization verifying center (AAVC) mechanism which uses cocktail-like concept, which is integrated network-layer and circuit-layer and application-layer together to obtain both security and convenience of telecommunication demands. The telephone number with an arbitrarily user-established authorization verifying code is used to protect this screen host gateway mechanism. When the sender dials the IP telephone, he must dial in the telephone number and then dial * (star key) and input the confirmed identification code, after the registration server and the remote-end verification database compare the verifying code, then it gives the connection transfer through. This research inquired the AAVC confirmation mechanism has confirmed the whole construction design of the query server and the verification server. Also, under the global telecommunication networkpsilas tidal current, this research founds one to have the jurisdiction management, active Anti-Spam and the IP service graduation authorization global numbering plan.
