Appears this and 8012701876 are working in tandem because get one dead call, then the other as a dead call a few hours later. 8017397948 shows to be Ymax Communication Corp landline for Salt Lake City area; 8102701876 shows to be landline serviced by CenturyLink for Salt Lake City. Caller ID for 8017397948 shows "Unknown;" 8012701876 shows "Murry UT."
Since there are so many home security scam calls going around since New Year's 2013, guess someone thinks they should start another one from Utah. Or possibly Rachel from Cardmember Services is branching out east from Washington state area codes. Who knows? All I know is that a call comes in as "Unknown" or with a location but not a name for caller ID, gets that number blocked. Good job whatever telemarketer you are--you are building huge client list for Digitone and other call blocker devices and services.
