That's what the retry feature is. If it's truly urgent they'll call again within a short timeframe (+3 to +300 seconds; not milliseconds like the 'try to go direct to voicemail' spam calls). I tell this to everyone I care for as well, if I don't pick up by the third ring, hang up and dial again. (This is to skip it going to voicemail and also differentiate the behavior). I don't expect scammers to pick up this tactic because it would double their OpEx and also make it more likely that they are targeted for actually trying to call your number with intent, rather than in error.

> I don't expect scammers to pick up this tactic because it would double their OpEx Except my missed call log is full of back-to-back calls from random phone numbers in my prefix. Either half the folks in Metro NYC (where I haven't lived in over a decade) are calling me to report the other half got hit by a car, or this adaption has already been made.

  That's neighborhood spoofing - the prefix may match, but if you're only allowing the exact same number to come through then the call would still be blocked.

  Same here, almost every spam call on my list has called again within five minutes, usually as soon as I decline the call.

>like the 'try to go direct to voicemail' spam calls The practice of leaving messages directly on voicemail bypassing the ability for the recipient to answer is commonly referred to as "voicedrops". I know this because a client asked for my compamy to implememt this ability, using carriers API first and successive calls as a fallback. Current regulations in the US don't explictly define this the same as a call, IIRC Canada does.

Except they do this and intentionally. They call, hang up as soon as it rings, and call right back. You are deceiving yourself if you think they are going to change their habits to avoid getting caught. They don't worry about getting caught, because no one catches them. One carrier shuts them down, they pick another. There are plenty to choose from, and plenty of greedy CLECs look the other way or join in.
