Call Server Configuration

Note: Embedded DNS server does not support IPv6

The embedded DNS functionality is not supported in an IPv6 environment.

You can enable these embedded DNS servers on the Embedded DNS page. This is a supercluster-wide setting.

Embedded DNS is enabled by default for newly installed RealPresence DMA systems. In its default configuration, the Call server sub-domain controlled by DMA system field is populated with the default sub-domain video.local. The system acts as an initial DNS server, resolving the FQDN dma.video.local to the virtual IPv4 address of the local cluster. If you change the sub-domain to a custom value, the embedded DNS service resolves dma.<newsubdomain> to the IP address of the cluster.

If you wish to use this feature, your enterprise DNS must place the Polycom RealPresence DMA supercluster in charge of resolving the sub-domain specified on this page. To do this, you must:

●Add NS records to your enterprise DNS so that it refers requests to resolve the site-based logical host name (see Site Information Dialog) to these embedded DNS servers.

●Configure your enterprise DNS to forward requests for names in the site-based logical host name to any of the clusters in the supercluster.

For more information, see Add Required DNS Records for the Polycom RealPresence DMA System. The following table describes the fields on the Embedded DNS page.

Field	Description
Enable embedded DNS service	Enables the embedded DNS servers.
Call server sub-domain controlled	The fully qualified domain name of the enterprise domain for which the
by RealPresence DMA	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.

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.
