8x8 Support

Recommended DNS Servers

Overview

It is best practice to first set up the DNS with the DNS from the Internet Service Provider (ISP). However, if issues still arise you can set the 8x8 GTM on the phones. Below is a list of DNS servers for multiple common ISPs.

It is not recommended to use Google DNS, as this will likely cause geo-routing issues.
