I have disabled and uninstalled them multiple times, this does nothing. I have used multiple versions of Skype, the problem continues regardless of version, currently I am on Skype 6.9. My internet speeds should be no issue, download is 117Mbps and upload is 34Mbps, according to Speedtest. No other VOIP program, or anything else has any internet issues. It can happen when I'm doing nothing with my network other than Skype, or when I'm playing a multiplier game with people. The problem can happen once when I join a Skype call, or five hours later. Echo soundtest only sometimes reproduces the problem. The cutting out isn't repeatable enough to test.

In a one-on-one call, Skype will sometimes tell me my connection is slow and then back to fast. I can understand everyone else perfectly. Sometimes instead my voice won't cut out, but will skip or stutter. In Skype calls, sooner or later my voice starts cutting in and out mid sentence my voice will go silent for several seconds, with no quality loss outside of the cut out.
