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.</td>

<span style=" font-family:'Arial'; font-size: 12pt;">I've had reasonable luck making a list of suspect Caller IDs though they seem to be slowing down the use of those as time goes by. In my experience, calls with these caller IDs are never valid calls. Depending on who's calling you may also have good luck blocking all calls with the same area code and 3 digit prefix. I store all this in the Asterisk database and wrote my own blacklist and whitelist functions to handle it in the dial plan. If you do this you'll need a whitelist to let the people who end up here because they've not published their caller ID to the lookup lists and one of get the default "800 Service" tags.<br>
