Call Server Configuration
Polycom, Inc. 275
The following table describes the fields on the Embedded DNS page.
To enable DNS publishing
1Be sure you’ve added the required NS records, one for each cluster in the supercluster, to your
enterprise DNS and have configured it to forward requests for names in the logical Call Server
domain to any of the clusters in the supercluster (see Additional DNS Records for the Optional
Embedded DNS Feature).
2Go to Admin > Call Server > Embedded DNS.
3Click Enable embedded DNS service.
4In the Call server sub-domain controlled by RealPresence DMA field, enter the logical Call
Server domain name (the enterprise domain for which the RealPresence DMA system is to provide
DNS) and click Update.
5Reconfigure your endpoints to register to the correct domain name for their site.
To determine the correct domain name for a site, go to Network > Site Topology > Sites, select the
site, and click Site Information. The Logical host name field displays the correct domain name. It
takes the form:
callserver-<site name>.<logical Call Server domain name>
For instance, if the fully qualified domain name for the logical Call Server domain is
callservers.example.com, the correct domain name for endpoints in the paris site is:
callserver-paris.callservers.example.com

Field Description
Enable embedded DNS service Enables the embedded DNS servers.
Call server sub-domain controlled
by RealPresence DMA
The fully qualified domain name of the enterprise domain for which the
RealPresence DMA system is to provide DNS. For instance, for the base
domain example.com, the sub-domain that the RealPresence DMA system
services might be:
callservers.example.com
This is the logical Call Server domain name for which you must create NS
records in your enterprise DNS. And this is the domain name that the system
combines with each site name to form the logical FQDN that endpoints in
each site should register to.
Note: Verify RealPresence Resource Manager Settings
If you have a Polycom RealPresence Resource Manager system integrated with the RealPresence
DMA system, make sure that in its Edit DMA dialog box, Support DMA Supercluster is selected and
Call server sub-domain matches the value in the RealPresence DMA system’s Call server
sub-domain controlled by RealPresence DMA field.
Enter all network/DNS-related information in all lower case to avoid possible case-sensitivity issues
with various devices and ensure interoperability.
