Spoofed number. Caller ID says "SSI" woman with heavy indian accent called to speak with my manager and "assured me this was not a sales call" I asked what the call was regarding and she said she wanted to ask some questions about our telephone line. I hung up.

when i google the number, it comes up for another company called Padgett Business Services

Looked up the "Operator" and it translate to Bilayn (Beeline).
