Well, I'd argue that with you because that's what the technician told me. i forget the specifics. But, to put it simply (telephone volume on handset at full), in Becker, where we had DSL, telephone and video, the handset often had to be turned down. In Ramsey, before the problem was fixed, the telephone handset level at full and I could hardly hear anybody on the other end. Once the tech fixed the problem, the handset worked in Ramsey, just as it did in Becker. (different companies, too) Did he lie to me?? Perhaps. It makes sense to me. A high impedence would effectively reduce the volume at the handset.
