I too was called multiple times by Ron Fisher of Olympia Group. He never wants to leave his name or number and usually just says he'll call back and hangs up on me. I've tried many times to get him to say something and I finally had to get rude and say, "Look, I'm the gate keeper. If you ever want to talk with him you'll have to at the very least identify yourself." He finally gave me his name & company. Then when I asked what this was in reference to, he hung up. What a time waster!
Ron Fisher called my extension (not my boss'). He asked me to talk to my boss. He knew his name. When I asked him the nature of his call (because my boss was not available) he said it was business related. I tried to get his phone number but was only advised that ... "he won't be able to reach me". When I tried to transfer his call to our voicemail message and told him about it then he said "bye". Be careful he is very persuasive and comes accross very natural... "business related individual".
