Chapter 2 Application Gateway and Broadcast Server Operation
10 Broadcast Server User Guide
You can also configure connection information for one or more LDAP
servers or CSV-formatted directory files, enabling the Application
Gateway to automatically supply Broadcast Server with distribution lists.
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.
