Got a call from this number with heavy white noise in the background. Some guy (who didn't introduce himself-- bad phone etiquette!) asked for the office manager. I told him she wasn't available and asked if I could take a message. He said no and hung up. I assume he was going to try and sell me something.

Got a call from the same number but didn't answe.  Caller id said "Sixtel LLC".  Salesman.

Got a call from the same number but no one spoke only listened. The caller id said sixtel llcc

Got a call today same jerky guy. Asked for office manager and I responded we don't have a designated manager what do you need, he hung up. Was not nice at all when he spoke.

Just received the same call - Asking for Office Manger - asked if I could take a message - he said, No, he would call back later.
