This is "Dialup Internet Access" (New Hampshire) dial up line out of Silverton, Colorado. No calls are supposed to be comming out on that line, It is likely "Card Services" (had any of those calls?) hacking their system to hyjack the number for call spoofing purposes. Dialup's regular number is 888-509-8555, call them and let them know what is happening and tell them you are reporting it to the FCC on a form 1088. AT&T and the other service providers like Level One Communications and Next Level Communications don't have a clue and they don't care about the crimes taking place on thier phone systems because they make money off of it also. Good luck and be prepared for a fruitless runaround. I have had one call so far today from this one and a bunch from other dial up access numbers in several states.
A person called on selling weed killer for ditch banks and yards. When asked what company he worked for the man hung up. This is very rude and unprofessional if this really was a business. I called the number bavk that showed on called ID and it was a Internet dial up noise I got!
