Clever Caller ID Tricks With VoIP

An anonymous reader writes "securityfocus.com has an interesting article collecting some clever exploits for VoIP. According to the article, using 'the open-source Linux-based PBX software Asterisk, used in combination with a permissive VoIP provider' can be used to fool caller id, and even get caller numbers that are supposed to be private."

    so is voip going to turn into something like the email spam mess once the peddlers of Mydixaflopin and their cronies start figuring out how to use it?

    The article states something of this kind: a 21 year old 'hacker' (quotes are mine) used VOIP line and a Linux based program named Asterisk to unveil blocked phone numbers and spoof his number. - well, that proves it, Linux is evil.

    Seriosly though, the only reason this is a problems is due to the fact that the VOIP providers are sending too much information to the end user and relying on the users' software to not reveal the caller's number.

    Clearly Linux causes invasion of privacy.

    It should be legal to burn places like that to the ground. You know the greatest good for the greatest number and all.

    That would make the problem self-regulating.

    So what?

    I should point out that it is possible to set your caller ID to 5318008. It was fun on an inverted calculator and I don't see how inverted caller ID is any different.

    The FCC would never tolerate an old-line phone company selling a service that lets people lie to caller ID...

    Wow... So that means every telemarketer that has called me in the last 12 years actually was physically and literally "out of area". That's mind boggling. They must all reside in some hidden dimension.

    and those of us that don't leave phone messages will never get in touch with you. a few months ago i tried calling a friend at his parents house. they do the same answering-machine screening that you do. i never left a message. i called 4-5 times within an hour. the guy's mother called me back.

    i guess the moral of the story is that if someone wants to get you on the phone without leaving a message, they can piss you off until the point where you call back.
