phreaking is just really about learning and exploring... the "black hat" equivalent of phreaking for the sole purpose of stealing calls is pretty much a dead issue since calls cost practically nothing now... most of the text files that you are going find on line are going to be outdated... beige boxing is still relevant for POTS lines, but is basically theft of services if you are not connected to your own line... not many people have 900 Mhz cordless phones, especially not ones that do not have DSS... there are a few still out there, but you are not going to hear much conversations with a radio scanner... it really depends on what you are interested in learning.. do you want to learn how different PBX systems work? do you want to find interesting stuff connected to different phone lines, modems, test lines, recordings? i would recommend starting by doing some hand scans... pick an NPA-NXX and scan a bunch of numbers... most of the time interesting telephone company related stuff can be found in the 99xx range... when scanning block your CID to prevent call backs from people, but anything interesting might use ANI, so learning how to get around ANI would be something to learn up on... 800-444-4444 will read back your ANI 804-222-1111 http://testcall.com/222-1111.html has got some interesting stuff you can do - it reads back the name on the caller ID, as well as doing DMTF decoding and an echo test... I was kind of curious about the scanner thing...I first got into ham radio and scanning because of the PLA's pranks with the modified Yaesu radios at drive-thrus. I came for the havoc, but stayed because...well radio is really freaking sweet (listening to someone's cordless convo was always fun too). Anyways, as the 900 MHz phone users die/upgrade to the higher frequency phones, is listening to them still possible on radios equipped for the higher frequencies (IIRC the newer phone bands are close to the more experimental ham bands) or are they all encrypted now?
