Edit Vertical Service Code Dialog
The Edit Vertical Service Code dialog lets you edit a call forwarding or hunt group service invoked when 
callers dial the vertical service code (VSC) for that service followed by the alias. These services are included 
on the Prefix Service page and can’t be deleted. But you can disable them or change their names, 
descriptions, or VSCs (shown in the Prefix Range column of the Prefix Service page). If you change the 
VSCs, be sure to inform users of the change.
The following table describes the fields in the dialog.

Embedded DNS
In a superclustered configuration, the clusters that make up the supercluster automatically take over for 
each other in the event of an outage. In order to gain the full benefit of this feature, however, the endpoints 
that are registered to each cluster must re-register to a new cluster when the new cluster takes over. 
This can be accomplished by specifying the gatekeeper or SIP proxy that each endpoint will register to as 
a site’s domain name, rather than an IP address. Then, when there is a failover, the DNS A record for that 
site’s domain name can be mapped to a different IP address, changing the Call Server that each endpoint 
is registered to. 
The embedded DNS capability of the Polycom RealPresence DMA system automates this procedure. 
Each Polycom RealPresence DMA server hosts its own embedded DNS server. It publishes a DNS CNAME 
record for each site. That CNAME record maps to the active cluster with which endpoints at the site should 
register. Whenever responsibility for the site moves from one cluster to another, the change is automatically 
published by the embedded DNS server. Endpoints will automatically re-register to the correct cluster.
