1) Let my filter out all calls not originating on an US/Canadian landline/mobile carrier 2) Yes, I’m happy to lose all calls that come via VoIP. 3) I don’t answer my phone anymore, so I miss those calls anyway 4) I’m very happy to sacrifice 1% of signal for 100% of noise

Relay the full trace of all IPs and switches involved in sending a call my way and give me a way to filter based on that trace. I want to block an entire source if they don't do a good job of screening their clients.

Similarly, if my phone would just allow me to do some simple filtering based on number or location, it would filter out 99% of all spam calls. I have a Florida number but have lived outside of Florida for about 2 decades. No one who I have any relationship with has a Florida number except for my family who are all in my contacts. Simply filter out my own area code but not in my contacts would eliminate the vast majority of spam calls. Yet, there is no built-in capability to do this on my iPhone as far as I can tell.

  ^ The fact I haven't lived in my numbers area code for a few decades as well I've noticed the exact same thing. If I don't have a contact for a number from that areacode it is 99.99999% chance of being a scam.

>Yes, I’m happy to lose all calls that come via VoIP At that point, why not just block everything other than contacts?

  Because lots of legitimate callers to me are located in the US, calling from a cell phone or landline, and I don't have them in my contacts. For instance, contractors coming to do work on the house may be calling from any number of cell phones, or people buying things from Craigslist. For Craigslist, if I were to filter out all the non-US originating calls and texts, would probably result in all the spam being dropped and at no expense to legitimate buyers.

    Those are all VoIP callers. Few businesses have enough copper phone wires for everyone in the building.

      They’re not VoIP callers. I’m primarily dealing with small to medium sized businesses, which use landlines, or cell plans like Verizon for Small Business, which are basically normal lines on normal cellphones.

        A ton of small and medium businesses use voip. Even residential landline phone service can be voip these days.

        To reiterate the problem: Legitimate callers don't all use VoIP. I don't have every legitimate caller's phone number in my contact list. Blocking all numbers not in one's contacts list is therefore not a solution to blocking spam calls while allowing legitimate callers.

        Yes, but many legitimate callers are voip so blocking all voip calls also isn't a good solution if you're looking to avoid blocking legitimate callers.
