This is a classic in America when calling Europe or International.

The dial out in corporate, usually you used 9. Then you google how to dial in Europe because the numbers are not natural. Google mentions dial 11 + country code + phone number.

So people hit 9 to dial out, then 11 to dial in Europe. Instantly you hear: Emergency 911, is this an emergency?

The dialer is like: no I'm trying to call Europe.

Wikipedia claims you should dial 011, so does that mean those people should have correctly dialled 9011?

9+11 specifically. Yes, a plus sign. 0 is also supposed to be mapped to plus or passed on when dialing external for compatibility reasons.
