cable modem dropping telephone calls

Oh, I think it's part of a generalized low-level hinkiness seen across many large scale systems caused by so many folks working from home- systems engineers, techies, etc.- with only skeleton crews on hand in many central facilities.

It's a credit to all of them- and the underlying technology- that things are working as well as they are.

Keep the faith. When things simmer down, all will go back to normal...

I don't think it is the increase in usage of the internet. This started before Christmas. We don't use the land line that much so has not been much of a problem. However now that the virus started up and our children do not visit that much now we are starting to use the land line more and it is getting to be more of a problem than a slight annoiance.

Never had a problem with my OOMA

The Internet has truly come of age. It is now clearly indispensable and has achieved reliability close if not equal to that of the old (POTS) telephone system. Now if we just had politicians who would use it inform themselves rather than just for propaganda purposes.

Just in time for zoom meetings.

You could call the Spectrum people. These modems have diagnostic capability and I would think they could do some diagnostic remotely, like loopback testing, etc. It probably also has some history of errors that it holds that they could read. It could be a modem/VOIP box problem, a cabling problem, or something else. Maybe they are sending replacement swap outs by mail, especially now.

I wasn't clear enough in my post.

The problem isn't so much increased traffic due to folks working from home- but that the engineers, QC folks and systems people are working from home rather than being in the office/data centers. I think this is what's reducing overall reliability and performance.
