So, whats a good way to get elevator numbers, do you just scan numbers of a hotel or apt building and hope to get lucky?
A lot of the elevator phones I see are just a two way intercom with no dialpad or headset.
From what I've read elsewhere, lots of elevator phones that aren't single "EMERGENCY" button-type are all simply just regular telephones plugged into a jack. On the ones that are like this that have an actual keypad (usually found on older elevators), you can find the jack, unplug it, plug another phone into it, and dial some numbers that'll read back ANI info. The jack is probably behind the panel and would take a little effort to get to, but honestly it all depends upon the elevator. Some might not even have a jack. It really all just depends.
I hear that they usually make it 100% unique from the building so that it can be accessed more easily and is more reliable. The ones that have single buttons saying "EMERGENCY" will directly dial someone, probably 911 or some sort of security center. If you're daring, you can ask them if they'll be kind enough to tell you what the number is
I doubt that'll go well.
Another way to find potential elevator numbers is to call a business and then scan the entire exchange.
Note: I do
not endorse nor recommend doing any of this! Disruption of the emergency equipment is probably some sort of broken law.
