Who called from 2122020948

this number has called my job maybe 20 times today and at least 3-4 times a day in the past.  some guy says he's from image or imagine systems.  i informed him that they will now be contacted by security for calling so much.

no one speaks after i answer the call

Same thing here.  He stays on the call long enough to be transferred to me, then drops off when I try to answer.

called for no reason

"Abel" called from a "systems company" and said his manager, Joe, wanted to speak with me. He would not say what calk was in reference to. Told him Jie would need to call directly and state the matter. He hung up
