DMA OperationsGuide Domains
242 Polycom, Inc.
On the Domains page, you can add administrative domains to or remove
them from the list of domains from which registrations are accepted.
If the list is empty, all domains are considered local, and the system accepts
endpoint registrations from any domain. Otherwise, it accepts registrations
only from the listed domains. This is a supercluster-wide configuration.
The following table describes the fields on the page.
Note
The Resolve to external address dial rule action (see “Add Dial Rule Dialog Box” on
page250) doesn’t ma tch ag ainst domains that are considered local. If the list of
domains is empty and all domains are considered local, this dial rule action won’t
match any dial string and can’t be used.
In some circumstances (depending on network topology and configuration), dialing
loops can develop if you don't restrict the DMA system to specific domains.
