The elephant in the room is that Australian landlines stop working whenever there is an NBN/Internet outage, or the power goes off. No 000 for you.

That's different, it's VOIP and it's part of your contract. Arrangements can be made to go around this.

But what happened here was, 000 calls that should have worked didn't, resulting in 4 linked death so far.

Having worked in that field a few years ago, I know that any minute in which 000 is inaccessible is a grave disaster. This was a colossal cluster f: 14 hours!

Interesting, the junction boxes here in the USA are full of 12v batteries to ensure they remain working when power goes out.

And when I was renting at a place with just VOIP, the modem had a slot for a battery to ensure the telephone remained operational when power went out.

Do neither exist in AU?
