Roll20 offers a built-in audio / video communication feature. If it works for you, in the LFG you can look for games that are listed for voice and/or video which don't mention a 3rd party program like Skype or Discord. Ask them if they are using the built-in Roll20 solution. Wiki docs, <a href="https://wiki.roll20.net/Video_and_Voice_Chat" rel="nofollow">https://wiki.roll20.net/Video_and_Voice_Chat</a>
