asked or business owner, when asked "what is this regarding", they hung up

received call from this number-- may have been from an Alltell cell number. wondering if Alltell is having problems in the 405 area code

This number called, just silence.

Received 2 calls this evening.  Just silence.

caled at about 19:01 CDT on a Monday evening. Told me it was my last warning about lower interest rates onmy existing accounts and to press 1 to speak to an account manager or to press 2 to sto the calls. I figured if it was my last warning pressing 2 would be redundant.

When I called back I go the three tones and "All circuits are busy now, please try your call again later" routine.
