People still use voice mail? I don't believe I've encountered one in at least a decade...
Where abouts are you? Here in AU, it seems everyone uses voicemail for their mobiles.

Re: Ringless voice mails from telemarketers
#13The article doesn't describe how the technology works. 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. Once this call starts to hit voicemail, the original call is dropped. I doubt phone companies let peop…
In the uk we have had the ability to send direct voicemail for years, one operator actively marketed the system before text messages took off as a method to message another orange customer without having to ring their phone.
EDIT: just called my voicemail and the option to direct leave a voice mail for someone else is right on the main menu (Three UK).

#15But 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.

Oddly, my number gets blown up by these things.

I can tell you that's exactly what they are doing.

If that is how it works, I can't see how they'll manage to argue these aren't calls in a court.
Re: Ringless voice mails from telemarketers
#19Hmm. I worked on voice mail systems in the 90s (by then they were already old and encrusted with feature bloat). This is actually how they work: like email or any other message delivery system. Messages are sent and delivered into mailboxes. The typical "ring-no-answer -> automated attendant" workflow that everyone sees as the face of VM is in fact an application layered on to of the base messaging service. If you know how (and it hasn't been administratively disabled) you can log in, compose a message and give it a recipient list just like email. Yoh can even schedule delayed delivery, ask for read receipt and on and on.

i am working on an application that sends calls straight to voicemail. there's "an api" for that in germany, meaning you put special codes between area code and number.
