I answered no one said anything I kinda figured it was a telemarketer. Some of them use computers to dail sequentially until they get an answer, if they are not paying attention the answerer gets what sounds like nobody is on the other end, but it is that their microphone is not switched on. Either way it is annoying. Thank you John for your info. I figured it was something like what you said, now I know for sure. I also received on from 507-990-4219. Same people I think.
