Dropping calls on both Comcast VOIP and Mobile WIFI Calling

Dropping calls on both Comcast VOIP and Mobile WIFI Calling

I have been having trouble for the last several weeks with phone calls dropping.  Here is what happens:

 

I will be on the phone and all of a sudden the person I'm talking to will no longer be able to hear my voice while I can hear theirs.  We then have to hang up and then try the call about a minute or so later.  The same thing happens when I am on my cell phone (AT&T) using the WIFI calling feature.  If we are on both lines, the calls drop simultaneously.

 

I have no other problem with my internet connection.  We have already replaced my modem and ran a new line to my house.  Am I missing something easy?
