A random tip - that may or may not work - when you need to answer a phone call from an unknown number: wait for exactly 4 seconds and then only say “hello”. Some automated call systems use this pattern to distinguish whether they are talking to another computer as a human will almost always follow up with another statement. If no other statement is made, the automated caller will hang up after another ten seconds. I have no direct information about what/which systems might work this way. Purely anecdotal. Hopefully, this flags your number as moon-human to reduce future spam calls.
