I’ve been getting over a dozen rando calls a day. Basically have had to put my phone on permanent DnD and then allow my contacts to bypass. No more!
This app is successfully blocking those annoying virtual numbers via STIR attestation.
Unfortunately it doesn’t fully block SMS. It blocks the notifications, but they still appear in your SMS app needing to be manually deleted.
I ensure contacts are allowed and high priority. I don’t block non contacts.
I check “include unverified” in the STIR setting. (The killer feature, imo!)
I give 30 days for call backs. (Not sure if needed but just in case?)
That’s it for me! Plenty of other stuff. There’s a GitHub page with some instructions but really the app explains itself pretty well. Tap those little question marks to get an explanation of what these things do.
Then there’s the test feature (bottom right green button) but it doesn’t test the attestation (it’s carrier specific). But it does use most of the other settings(if you enable them). And sure if their carrier doesn’t support the attestation that is going to be unverified and get blocked, unless they’re a contact(I believe.) I’m fine with that. I live tested it with a neighbor and they called me and my phone rang.
I haven’t even had this thing installed for 24 hours so I am by no means an expert.
