Hi We are looking for solution to prevent Fake calls being terminated to our VOIP Gateways. Our requirement is to build up a dynamic blacklist/white list which can automatically detect fake generated calls either by the number format pre assigned. (i.e. 93701111xxx) or by number of call attempts from a specific ANI OR to specific DINS (i.e. 93702222222 hitting to GW more then 5 times in 1 min.) all those calls should be rejected from the FS before they hit to voip gateway. Currently calls are passing thru our switch directly to the gateway and we are manually blocking such numbers, however we are looking for solution to automatically detect the number and block them if they are not pre configured to block. Let me know if you have any query. Please advise if any one has such solution readily available or can develop and if so how much it will cost.
