I have a system set up that gives a different ring for phone calls versus fax attempts.

I no longer have a fax machine hookedup, but the fax tone is still active.

When this number calls, it comes thru with a fax tone, so I'm assuming that's what it is.  No message is ever left.

This number leaves only hang-ups on voicemail.
