We get several calls a week from this number, asking for various employees by name. No caller ID just says Chicago IL. We screen our calls and these people can never give a project name or a reason for the call so they don't get through, all they will say is their boss asked them to contact so&so and transfer the call when they are connected. Most likely telemarketers or recruiters/head hunters.
Recd a call a today. Said hello multiple times and I responded with a hello as well. He pretended he did not hear few times I said hello. I think he was recording... Not sure why.... Forgery, ID ??? Perhaps
He Had correct correct first name but wrong last name. When I paused and responses, noooo, he very courtesy and quickly apologized. I hung up. This is a phish attempt for identity theft... beware!!!
Some sort of name-to-number enumeration scheme, they call and wait for you to introduce yourself, then repeat your first name back to you with incorrect last name and hope you correct them, then apologize and say they have the wrong number.
