If you have audio problems and you are working behind a Firewall you must check the following parameters.
First try opening the following ports and do a test:
TCP only: 10443 and 10444
TCP and UDP: 3478
If the problem persist, open these other ports in your Firewall
TCP only: 5090
TCP and UDP: 10000 to 65565.
Also if the firewall allows it, prioritize everything on *.toky.co
If this doesn't solve the problem, please contact our customer service team.
