But HOW does it work? It's not clear by the article precisely how this is done. Possibly a triple call system. Three calls to that same number at once, each a millisecond after the other, and when the third hits the voicemail the other two disconnect immediately.
You really only need a double call. It's quite easy. I wrote this ages ago http://edoceo.com/exemplar/call-to-voicemail Oddly, my number gets blown up by these things.

Due to the slow speed (100 voicemail/min) its likely what they are doing is initiating a call far enough for the phone system to busy out your phone, then very quickly placing a second call that the phone system sends straight to voicemail as your phone is busy.

I assume we're talking about a very narrow window here, right? How narrow?
Is it something that has always existed, or something that crept in because of the transition from phone-as-mechanical-device to phone-as-software?

#23People still use voice mail? I don't believe I've encountered one in at least a decade...

This is fascinating. It never occurred to me until now that there might be a window in the call process between "line is flagged as busy" and "phone rings." I assume we're talking about a very narrow window here, right? How narrow?

On a related note, I'm still surprised to find that telephone operators haven't fixed the scenario "someone calls me and I just miss it, I call them back while they're trying to call me for the second time, and we both get a busy signal". As a naive outsider, seems like it wouldn't take much to just connect those two calls.
