VoIP Calls Dropping and Lag

@user_2c43a8 

Anyone able to help with why my internet keeps dropping out randomly and causing my audio on VoIP calls to drop as well as my wireless tv box lags constantly. I have the best plan and best xfi router/modem. Tech said everything looks great but still having the same issues. Work from home everyday and will need to change services if I can’t get this resolved ASAP. 

Did the tech check the lines outside?

If you log into the gateway, what do the upstream/downstream signals and the error log look like?  Post them here.  You have to redact the MAC addresses or the bot will hide the post (personal information).  About halfway down on this page gives some guidance:  https://forums.xfinity.com/conversations/your-home-network/internet-troubleshooting-tips/602dae4ac5375f08cde52ea0 

It's a snapshot in time.  Try to look at it when your internet is messing up, or when your TV is lagging.  Might have looked OK when the tech was there, how about other times?

Recently our apartment builing call box (voip) is going right to voice mail. Seems that calls from other phones go right through, only the voip calls from the call box do this. Mostly xfinity but sometimes Verizon. This started happening in September and there seems to be more each week.
