Who called from 2072500197

I keep getting calls and there is nobody there.  almost daily calls.  Very annoying.

This number keeps calling and they either say nothing and then hang up or eventually make some type of sound then hang up.  Caller ID reads "Waterville  ME"

If you do a phone number lookup on 411.com it states that there is no match - interesting

Tried looking up the number on "whitepages.com" and "switchboard.com" both came back with "No match found". Reported to "Do Not Call" again but as usual with the any government agency nothing gets done!!!!

we get at least 4 calls a day from this number..never an answers and when we call back its always busy.
