Overseas caller asks for IT guy, then anyone in the IT department. Probably selling white papers or some such dross.

Called me at work trying to tell me about a microsoft document aimed at "professionals such as myself." I told him off and hung up on him.

SO RUDE!  He called ... I answered ... He hung up without saying anything.  Called back seconds later ... I answered ... He asked for a co-worker that I out of town (which I informed him of) and he immediately hung up (AGAIN!) without saying anything.  He'll be blocked from calling again!

This guy has called several times.  Yesterday on my voicemail he didn't realize the mic was open from one of the many calls his robocall system made.  He identified himself as George.  It's hard to tell from his accent but the last name sounded like "Farsquaad".  He also said he was from "SumoLogic", although I'm sure they are just a call center doing work for SumoLogic among other clients.  I heard him talking to some poor sap who answered one of his calls where he was pushing to talk to a specific person even asking when they would be back for him to call again.

Female caller asked for the President of the firm, said she was with CTI
