(720) 325-xxxx numbers are from a debt collector. They will call several times a day until dealt with. It has gone on for approx. 6 months for me! Good luck getting rid of them.
Similar to 2755 and 2725, I wouldn't answer any of them. Many times they are trying to identify and tie your name with your phone for whatever reason. Once they get this done they can sell your number to a variety of entities as well.
