Keeping spam in mind seems like a really good idea. I'm also a big fan of keeping a cryptographic "paper trail" so that one can figure out who spammed. On the other hand, is SPAM / SPIT a big enough problem at this point to warrant scuttling any interconnectivity? It seems a bit premature to worry about a problem that may not develop for 5 years and allow that fear to stop direct sip dialing. As an amusing aside, I inadvertently added a "captcha" to my phone line when I had the local number go into an IVR that asks the caller to press 1 for person XXX and 2 for person YYY and 3 of they are a telemarketer. I don't think anyone other than my friends has ever pressed 3, but the predictive dialers used by the phone-spammers doesn't seem to pass the turing test and isn't able to press 1 or 2. ;-) I see lots of timeout-hangups in the IVR with caller-id's like "CAR PROMO" or "VOIP CALL". If spam/spit is ever a problem, I'm simply routing previously unseen calls to a turing test of the same type and anyone that has previously called (and/or been called) gets to bypass the turing test. -wolfgang -- Wolfgang S.
