Note: We highly recommend consulting an IT or network professional when configuring advanced network settings or devices. 

The following options and port settings are typically available in your router/firewall's web interface (GUI) and are generally required to ensure quality 8x8 service. (Not every setting will be available in every router.) Consult your network administrator and or your manufacturer's documentation for more details on setting up your router for optimal Quality of Service (QoS).

For your convenience, routers and firewalls pre-configured for optimal QoS are also available from 8x8. Contact your 8x8 Sales representative to ask about ordering.
