Know this number??? Or who it is?

Have called my home several times. Nothing but a bye at the end. No idea.

Yes, they called me twice in the last few weeks. After a long pause, I hear "goodbye" and it gets disconnected. When I call the number back, the recording is in Spanish. The 905 area code is in Ontario, Canada. I live in Florida. I have no idea what the heck this is all about.

It is a Spanish company regarding telecom or something.  Unsure, can't speak Spanish!
