No one ever says anything, no recordings, no sound, just disconnects after a few seconds.

Repeat calls from 920-365-5501 Every time we answer they hang up right away.  If we do not answer they do not leave a message.

CID shows Algoma WI - click over from Robo dial to loud call center.  Fairly certain that they call as well from 920-365-5498 and 920-365-5884, all three CIDs show Algoma WI with same loud call center.  Various callers attempt to sound important and claim they NEED to talk to the controller, CFO, owner, etc.  They have been calling periodically for 18-24 months.  Early on, I transferred them to voicemail and they would immediately hang-up and call back.  That's the second sign of them being B-S.  I simply disconnect them as soon as their numbers come up now.  Don't know who they are, don't know what they want, don't care.  They're scum.
