Refer to google carnivore project. Basically they monitor all convos , then they archive in case of need as in Intelligence gathering . Like who did that guy call in last 60 days. They can do voice comparisons on the tapes and find approx matches then manually discard false positives.
They can also do realtime switching as in say a specific word or more and then it gets filtered by a machine to a level 2 system that also filters.. Carnivore project sends 1 call ever million to a nsa agent. Meaning 1 out of a 1000 gets sent to the agency realtime. 1 out of that 1000 is live monitored. Consider it like a 'I got a bo...b' phrase in an airport. They trigger on specs and then the software does the rest. That does need affiliation with major players but carnivore is unix based and acts like comview in a way that it sniffs the packets on the lan The guy that worked with fbi ,nsa on this is the guy that works on the recognition paterns ( I think it was dragon dictate) or similar products. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of trixter aka Bret McDanel Sent: Tuesday, June 13, 2006 9:47 AM To: Commercial and Business-Oriented Asterisk Discussion Subject: Re: [asterisk-biz] FCC ruling that requires all VoIP providerstomakewiretapping On Tue, 2006-06-13 at 09:25 -0400, William Piper wrote: > Can anyone tell me what is involved in a wire tap on a VoIP line? > Wouldn't the monitor command in the manager API work, or is it more > involved than that? > it should be automated on a per person basis. The patriot act opened it from a singular number to a person, so they have to tell you the numbers, you dont have to guess but they can come to you and tell you that anything 'this guy' sends you have to monitor. The monitor command will be sufficient. I have seen CDs of FBI and DEA wiretaps that were either CD audio or mp3s, wav should be fine as well (PCM format - standard MS). There isnt a legally defined standard as to what format the audio needs to be in, although generally companies work with the government on this and provide it in standard formats. The title III warrant (what is needed for a wiretap, CDR records only need a subpoena however as they are business records) get renewed every 30 days. They have to be presented before any calls get monitored, etc. Now if the government was listening to everyones calls like the claims go, why do they need this? Kinda makes you think they arent doing what is claimed. > -- Trixter http://www.0xdecafbad.com Bret McDanel Belfast IE +44 28 9099 6461 DE +49 801 777 555 3402 Utrecht NL +31 306 553058 US WA +1 360 207 0479 US NY +1 516 687 5200 FreeWorldDialup: 635378 http://www.trxtel.com we pay you to terminate calls with us! _______________________________________________ --Bandwidth and Colocation provided by Easynews.com -- asterisk-biz mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-biz
