C7100V - Xfinity voice choppiness
I see this issue arose some years ago on this forum: that is, incoming calls are so "choppy" that I can't hear the caller, while it seems at least much of the time that the caller can hear me. The so...
Event log look ok, only a couple of criticals seen. If there were more or Errors or Warnings seen, would need the ISP to take a look there.
I see lots of Correctables and Un-correctables on the cable connections page. These channels should show zeros here.
Have the ISP check the signal and line quality UP to the modem. Be sure the ISP provisions the modem correctly.
Be sure there are no coax cable line splitters in the between the modem and ISP service box.
Be sure your using good quality RG6 coax cable up to the modem.
Start with removing any amplifiers, signal attenuators, or splitters from the coax.
From there check the line for kinks, damage, moisture in the line.
Check the connectors for improperly made ends, foil touching the copper coax line, loose connections, bad/old/cheap connectors, or corroded connections. Replace them if you do.
Be sure to power OFF the modem for 1 minute then back ON.

Thanks very much for your help, I really appreciate it. I will follow the links you provided to do some reading. I have just one question about what you wrote. What does "Be sure the ISP provisions the modem correctly" mean?
Oddly, at least to me, when I view my Xfinity account online, it states "We can't connect to your device." In fact, when I attempted to reset from the website, I'm not sure a reset occurred. I would check that again now but my wife is in an online meeting.
As for checking the internal wiring as you described, so far as I know it's a single run to the 7100; if I can find it in the basement, I suppose I'll just replace the whole thing. It was installed in 2013. Other than the telephone problem, all else is well; wifi is excellent.
Thanks again!
Means that the ISP gets the modem associated with there network properly and also sends the the right configuration file they use with the modem on there network.
Ya, if the status shows not being able to see the modem, the ISP needs to take look into this.
Also have the ISP check the speed package support for this modem as well. I think is only supports speeds up to 600Mbps.
