Thank goodness that poor DR. is dead.  His estate should sue all you people for defamation.  
That said,  today this is a local broadband number made available by AT&T or DISH when routing PC calls that are made from the Verizon communications network. One of your friends or relatives has verizon or dish cable communications and tried to call you from their computer. In some cases, your caller was probably unaware that the call had been connected, and was trying to figure out how to use the microphone, or had their speakers turned down too low to hear you answer.  I put down fax machine because this is new technology and not many folks know about it.
