"In general, no audio on a call is caused by you, blocking something that Google Voice needs to work.
If you are using a VPN, it must not block WebRTC.
Do not block javascript, HTML5 nor WebRTC
Do not block any
google.com cookies
Temporarily disable all browser extensions to see if audio now works. If it does, then selectively enable extensions one at a time, until you find the culprit."
Thanks for the response. I've been using express VPN loaded on a router with the OBI for over a year as I am in a country that blocks VOIP. I'll have to check with express VPN and see if they've changed something on their service.
