The DNS should also have entries for your Active Directory server (if different 

from the DNS) and for the external database server being used by the CMA 

system.

To dynamically manage endpoints (which includes automatic provisioning, 

automatic softupdate, and presence) right out-of-the-box, they must be able to 

automatically discover the CMA system. This means you must add the DNS 

service record (SRV record) for the CMA system. The lookup key for this 

service record is _cmaconfig._tcp. So the record will resemble this:

If during First Time Setup you did not configure the CMA system to use an 

external Microsoft SQL Server database, but need to do so now, see 

Integration with an external Microsoft SQL Server database is required for 

redundant CMA 5000 systems or for CMA 5000 systems supporting more than 

400 concurrently registered endpoints and 240 concurrent calls. 

If during First Time Setup you did not configure your CMA system to use an 

enterprise directory, but need to do so now, see 

page 355.
Connecting to an enterprise directory allows users to enter their network 

usernames and password to log into CMA system. It also allows users to 

access the enterprise directory when selecting conference participants.

If you configure the DNS server to use two or more Active Directory servers, make 
sure that the servers have the same services available.

It is not recommended, but you can create the CMA system databases manually 
using Microsoft SQL scripts. Contact Polycom Global Services to request the 
creation scripts.
