Suppose you are apart from the mobile or whatever phone (so can't call 112 or 911 or 999), but have have access to a computer with internet connection.
How do you call/message an emergency service (of whatever country in hope they will route the request to the correct destination) using only Internet?
Maybe there's some 911-like website or public SIP or whatever? Or better go to some chat/forum/StackExchange/whatever and ask somebody to make a call for you? (will users really believe?)
/* 1. I'm not in any emergency, just curious. 2. I'm not sure on what SE site to ask this question. */
