Got a new cell number recently and began receiving calls from this number.  When I did a look up it show as MCImetro Access Transmission Services in Natchitoches, LA.  When I Googled the company, I came across this website which had several listings for scam calls from this company.  Haven't answered the calls because I didn't recognize the number -- I thought it might be for a person who had the phone number previously.  They do not leave a voice message.
