 # Validate a domain for direct routing
 
-This article describes the process of validating domain name ownership. A fully qualified domain name (FQDN) consists of two parts: host name and domain name. For example, if your session border controller (SBC) name is `sbc1.contoso.com`, then `sbc1` would be a host name and `contoso.com` would be a domain name. If there's an SBC with FQDN of `acs.sbc1.testing.contoso.com`, `acs` is a host name and `sbc1.testing.contoso.com` is a domain name. To use direct routing, you need to validate that you own the domain part of your FQDN.
+This article describes the process of validating domain name ownership by using the Azure portal.
 
-To configure direct routing configuration in Azure Communication Services, you first verify domain ownership for your SBC FQDN. You then configure the SBC FQDN and port number and create voice routing rules.

-When you're verifying the domain name portion of the FQDN, keep in mind that the `*.onmicrosoft.com` and `*.azure.com` domain names aren'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.

 If you're using a subdomain, make sure that this subdomain is also added and verified. For example, if you want to use `sbc.acs.contoso.com`, you need to register `acs.contoso.com`.
