[LINK] Odd phone calss

[Fred Pilcher]

For a while now we've been getting odd phone calls - landline, not 
mobile. They seem to come in batches - we'll get a few, then none. There 
are two specific calls, both clearly recordings.

One is quite quiet and garbled, but ends with something like "How about 
a massage?" (It doesn't sound anything like an add for sex services - 
it's a male voice without any hint of the risque.

The second is a female voice. The recording is designed to sound like 
she can't hear you. It's one of those "Hello?",,,"Hello" things. How do 
I know it's a recording and not a genuine caller who simply can't hear 
the replies? I've had it several times, and the pattern becomes 
detectable - it's the same thing every time.

The accents in both are definitely Australian.

Does anyone have the faintest clue what this could be about?

Cheers,

Fred
