A solution already exists...
...and it's call screening. It's been around for decades. If you call a company with the intent of speaking to the boss, you're probably going to talk to a secretary or receptionist first. They get your name and in some cases make a determination as to whether or not your call should go through. Businesses get lots of junk calls, too, and screening out the garbage is part of the job.
If you've ever used Google Voice, there's an option you can turn on that does this to some extent. When someone calls you, they have to state their name. When your phone rings, the friendly automated assistant announces the caller. You can decide whether or not you want to take the call. It may not be perfect, but it's a heck of a lot cheaper than hiring a personal assistant. Perhaps all telcos could offer this type of service for a fee.
The bottom line is that someone (or something), somewhere, with some level of intelligence needs to make a decision. If you're not willing to make that choice, then you need to outsource it to someone/thing that does.
I don't believe there's an technical solution that can permanently get rid of robocalls. Even if someone does come up with some sort of technical solution that involves codes, voice, or signal analysis, robocallers will come up with countermeasures to circumvent this. As stated in other threads, any real long term solution would have to involve legal or economic penalties, but even those aren't guaranteed to work.
