Panda, you've missed nothing, as far as I can tell. We've all thrown all the possibilities at mbtel, as well as how to detect the source of the problem. He has informed us that he Copped-out, and set up room-to-room call block. We all informed him, each in our own way, smile , that all he did was hide 1 problem and create another. I think he has decided to ignore us and hope that a sleeping dog will lie quietly, and not create a 'stink'.
If I worked in the Houston area, I believe I'd be contacting motel Mgr's looking for the one that has a front-desk crew that is REALLY irate about room-to-room call complaints. I can always use another customer! John C.
