A few weeks ago, outgoing calls from our Panasonic phone system (base station plus wireless handsets) began dropping after 20 - 50 seconds. Xfinity tech rep had us plug the base station directly into the modem - didn’t help. He also found water / ice in the coax connectors and replaced the line all the way to the pole - didn’t help. We plugged an old-fashion wired phone directly into the modem - didn’t help. Xfinity tech rep’s only other thought was that we had a modem problem.
Has anyone else experienced this problem? Does anyone have a suggestion?
