Enter a FQDN for the SBC.

{% hint style="info" %}
Make sure the domain name portion of the FQDN matches a domain that's registered in your tenant, and keep in mind that the \*.onmicrosoft.com domain name isn't supported for the SBC FQDN domain name. For example, if you have two domain names, contoso.com and contoso.onmicrosoft.com, use sbc.contoso.com as the SBC name.
{% endhint %}
