This is exactly what I do - “press 1 for a human”
Works great

Subject: Re: [asterisk-users] Block Spam Calls
Most spam calls are robocalls these days. At my house, I can block pretty much
all of the robocalls by requiring the caller to take some action before ringing
the phones. In our case, the action is just to dial 1 for my wife or 2 for me.
The only difference it makes in the end is which voice mailbox the caller gets
transferred to if no one answers, but since asterisk so programmable, there are
a lot of ways to accomplish the basic concept. I can see tons of calls in my log
that never get through to bother us.

Hi All. Does anybody know if Google/Android has an API I can sign up for that
will allow us to query the caller ID and find out if it is spam or a robocaller?
I ask because we've had increase in spam calls and I'd like to simply
play dead air or something really annoying.
Thanks all,
Alex

I have now changed the dialplan slightly so that the first time people call they are asked to dial 1. After the first call, they are added to a known caller list and get straight through, and any robocalls at that point are blacklisted manually. I have found that most robocallers spoof the Caller ID so rarely call from the same number twice. It means that legitimate callers who cannot dial 1 just have to dial again to get through to the phones - there is a recorded message telling them to dial 1 or call back. I haven't had a robocall since! The hardest thing about this was extracting all the numbers of previous callers from the CDR and adding it to the Previous_Callers AstDB for the lookup. I didn't want to make existing callers go through the initial learning process. -- Best regards, Julian mailto:jb_soft at trink.co.uk
