Slightly simpler, you can pick up a telephone recording box I had a cheap one that hooked into the handset, but I believe the deluxe model goes right into the wall jack http://www.radioshack.ca/estore/SearchResults.aspx?language=en-CA&keywor ds=telephone+recording+control&pagenum=0&category=Telephone+Equipment+Ac cessories&catalog=RadioShack The hardware shouldn't be difficult at all, I'd like to see how the software works I was once told that you could record a 14.4k data stream, and play it back into a modem to demodulate both sides, but I can't imagine how it would be done. -----Original Message----- From: Deus, Attonbitus [mailto:Thor () HammerofGod com] Sent: Tuesday, July 02, 2002 12:20 PM To: Evrim ULU; pen-test Subject: Re: blind demodulation - sound card - lucent winmodem - new topics -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 At 12:33 AM 7/2/2002, Evrim ULU wrote:

Pretty easy- just take the analog pair and send it in- however, when I made a cable for this, I put a TR80 transformer (IIRC) in-line to keep the ring voltage from frying my box. hth AD -----BEGIN PGP SIGNATURE----- Version: PGP 7.1 iQA/AwUBPSHgzohsmyD15h5gEQI3vwCfWOSZecJFs3M4F6CGl83lOVv1HtoAoLw3 8E/KWFiRjO6mZARydqYmidiK =Eq/H -----END PGP SIGNATURE----- ------------------------------------------------------------------------ ---- This list is provided by the SecurityFocus Security Intelligence Alert (SIA) Service.
