Chapter 2 Application Gateway and Broadcast Server Operation
You can also configure connection information for one or more LDAP servers or
When the Application Gateway detects that an IP telephone has come online, the Application Gateway collects from the IP telephone its MAC address, which it then uses to look up the phone’s extension in the IP/DN map. The Application Gateway sends that information to Broadcast Server where the information is used to update the subscriber list. The Application Gateway also uses the phone extension to locate the associated department name in the directory. The Application Gateway sends the department information to Broadcast Server where it is used to update the distribution list.
Any time that a particular telephone is updated, the Application Gateway collects the updated extension, user name, and department and sends that information to Broadcast Server.
If an extension is no longer used, it is not automatically removed from the distribution list, as the system has no way to determine if the extension is temporarily or permanently out of use. To remove an unneeded extension from distribution lists, use the Distribution List Membership page.
