We just replaced the DECT telephone connected to my mother-in-law’s Connect Box on the analog port. She had noticed that during almost all longer calls the sound ok the start but was getting broken up (missing sections and robot sounds) after about two minutes.
We thought it was her telephone since it was an older model but we still see the same problem with this new (senior friendly) telephone and new cable. Just called UPC support and they are sending her a new Connect Box. We don’t use the fixed line much ourselves but now have the same issue also happening after about 2 minutes. It seems to be a new effect in last two weeks.
Any suggestions? To be honest it seems unlikely to be the modem/hw related (2 different sites showing same issue in a short space of time).
