I've never heard of this before. Unfortunately after checking it out, it looks like my carrier only offers it for iphones. This does look like a handy feature though.

There's two I get regularly. One is from people pretending to be the Canada Revenue Agency. The other is a message in Cantonese, that according to my coworker who gets them too, is from someone pretending to be from the Chinese embassy basically saying the same thing as the fake CRA one. That you owe money and a lawsuit is being prepared under your name, without actually mentioning your name. The one from the 'CRA' is almost comical. It sounds like something a child would say. I've talked to the government enough to know how they talk. They also don't use odd voice concealing effects typically.

I actually called the number the CRA one left back once and a person with a French accent answered pretending to be from the CRA. I just said if they called my number again I was going to report them to the rcmp and then hung up. It stopped for a few months after that. I'm assuming if it was actually Canada revenue, they would have called back. All I was getting were the Cantonese ones. The CRA ones only started again recently.

I wholly disagree. The system as it works today is miles better than a circular buffer. People trying to leave new voicemails are informed that there is no more room and thus they know that if it is important they should try calling back later.

If it just deleted old entries then it's possible someone left an important message and assume you'll hear it but then it just gets silently deleted.

Imagine if PC storage devices worked this way, it'd be chaos.
