4000 system is not available in redundant configurations or maximum 

security configurations.

• The dual microprocessor CMA 5000 system can support up to 5000 

concurrently registered endpoints and 3000 concurrent calls in direct

also available in an optional redundant configuration.
Integration with a corporate directory is optional for CMA 5000 systems. 

Integration with an external database (Microsoft SQL Server) is required 

for redundant CMA 5000 systems or for CMA 5000 systems supporting 

more than 400 concurrently registered endpoints and 240 concurrent calls.
