My mother had me look this phone number up also. She got a call this morning, same thing happened. Asked for my dad and when my mom said he wasn't there, they disconnected and my mom said it sounded like a fax machine number.
I believe what people are reporting as a fax machine noise is actually a computer modem as this number shows up as a dial-up number for an ISP.
I've also been receiving calls from this number and I blocked it the first time it showed up and have never answered it.
caller asks for my husband. When I ask who is calling they answer Farm Supply. He is responding to a request for weed and brush removal. We have no need, as we live in the burbs.
