Social engineering imo. Knows the boss, number spoofed, International company, has cell phone number, calls everyday. Block this number immediately for your own good. If you don't know how to block, call the phone company. On Voip you can route the call to a black hole.
Someone from this number just called our office; the person they wanted wasn't available and hung up on me. I will remember the voice and trust me what ever tellamarketer you are, you will NOT get through even if the particular person is on the line after hanging up on me.
This number comes up at least once a day and I just get "I'll try again later" - never a message. Sure sign of a salesperson and someone who can just keep calling because they aren't getting through to the boss.
A gentleman from this number calls my office at least five times per week. No exaggeration! He asks for one specific person each time... When he does not get an answer, he'll call back and proceed to PRETEND that he knows the individual personally by saying that he will just "call his cell". One incident, he probed me with questions when he couldn't get through to that person during an entire week.. asking me things like "well, is he on vacation?" or "when will he be returning to the office". I do not feel the need to give any harassing sales person information regarding ANY of our employees. The guy is rude each time he calls and never explains what he calls for.
Caller says he is from ISM. Caller becomes rude when questioned about the nature of the call. He won't say what ISM stands for, only that it is the name of his company. He won't say what his company does!! He just pretends that our President/CEO knows him and expects to be put through to him. "Tell him I'm on the line." Yeah, riiiiight.
I researched the number 414-221-1700. It belongs to International Sports Management in Milwaukee. In other words....sports marketing and 'hospitality'.
