I really like this... except you should add a special case for 911. I strongly believe that all phones, and anything that looks like phones, should be able to dial out in an emergency.

Obviously, this can raise its own problems -- you'll have to train the kids not to randomly dial 911! -- but you never know what circumstances might exist where someone in a panic reaches for the nearest phone.

Kari's Law [0] is relevant here. Not strictly applicable as this is not a MLTS (phone line multiplexer), but very much in line with the spirit of the law as it was adopted after a child was unable to dial 911 from a motel phone.

Also if you want to test dial 911 I’ve been told you can schedule a test call with you local dispatch!

I setup a phone system with Asterisk for fun a while ago and I avoided emergency calls because I didn’t know how to safely test it

You can, but you should prefer dialling 933 which will use the same routing infrastructure, and reads out the address that 911/933 believes is associated with your connection. Does not take time away from a human dispatcher so should always be preferred unless there is a critical reason to test 911.

Hmmm, I wonder if something like this applies to testing emergency-apps on my smartphone.

Unlike a landline, it's harder to say where it ends up or who'll get angry at you for "testing".
