Work in the Netherlands and I've received 10+ calls today with intervals of a few minutes. Sounds like a fax machine but when I called the number I got a recorded message in French I believe. Cannot make heads or tail out of it.

I m getting calls from the same number about a 100 plus calls in two days and sounds exactly the same like a fax machine. And i am getting calls on both my cell phones and one is a private number

The exact same happened to me today. I think we shound not try to call them back. You never now if they will try to trap your mobile number and charge you for the long distance call.

It is a online fax service.
