Who called from 2026250400

Just had this number call my work line and ask for the colleague who used to sit at my desk.  He was persistent asking if that person still worked here and what type of phone line it was.  I repeatedly told him I couldn't disclose that information and that didn't make him happy and he eventually hung up.

Caller asked my first and last name and hung up.  Phone number comes up disconnected if I call back.

same thing happend to me he asked me if it was me and I never said yes.  I asked who it was and they said it was regarding a package.  This is a scam they record you saying yes to your name and then you get charged for something and apparently they have your voice saying yes that you agreed for purchase.

Same thing happened to me.  He asked for another person's name who works for our company.  I asked what it was about and he said, "a UPS package".

same thing occurred today - a direct call to my office.  foreign caller asked for me by name and when I said yes, he said Oh hello!  then hung up --- what is going on?  (I called back the number and it rang 20 times - no answer)
