In case you're not familiar, "ringless voicemails" are a fairly new, particularly sleazy tactic that are starting to be used by marketers, bill collectors, etc. They deliberately sidestep call blocking and all existing laws (like the "Do Not Call List", etc.) A voicemail just pops up without your phone ever ringing. This is doubly annoying because it takes some effort / time to delete a voicemail as opposed to simply deleting a call or adding the caller's number to your blacklist / blocked caller list.
For now I've just disabled my voicemail but short of that, does anyone know of an app or similar technology that can be used to simply block them from being sent in the first place (bonus points if you know of an app or invent one that intercepts them, makes 10,000 copies of the incoming voicemail and then returns them to the SENDER'S voicemail box without them ever getting to me).
