The linked Reddit thread has a whole subthread about that. A bunch of people who claim to be phone system installers say they regularly call 911 to test that it works. Apparently it's fine as long as you tell them that it's just a test and maybe ask to verify observed phone number and location. They probably don't like it if you just call and hang up and then don't answer any callbacks.
