Domains determine if the Session Manager Dial Plan can route a particular call and if a SIP user is part of the enterprise SIP network.
For example:
Session Manager receives a request to 123@myserver.avaya.com
myserver.avaya.com is not administered as a domain.
Session Manager checks dial patterns for avaya.com
You can create SIP domains and sub-domains on the Domains page.
A Domain name can be <organization-name.domain>. For example, avaya.com or abc.org.
A Sub-domain name can be based on the geographical location or any other corporate requirement such as an office location. For example, us.avaya.com and fr.avaya.com can be sub-domains for Avaya offices in the U.S. and in France.
