I think it is used as a VoIP gateway in to Australia, some Indian sounding call centre tried to flog me solar panels

Several calls today - no one speaks just a series of beeps. Very annoying.

Calls every 2 hours, bout solar panels (only just picked it up to stop the calls) definitely a scam - Indian sounding

Called without leaving a message.
Rang back and call disconnected. Scam.

Three phone calls today - no message -

Call from someone about solar panels - knew my street address, when I said I was renting she hung up in my ear!!!

Called me but I missed the call. When I called back 2 minutes later I got a message saying this number is disconnected. How does that happen unless it's some sort of scam?
