Designing the CallManager Centralized Solution
In this section, we’ll discuss the centralized CallManager design. Each CallManager
is capable of hosting 2500 clients, and CallManager can be clustered together in a
logical manner to provide backup and redundancy to each organization.This section
is devoted to presenting CallManager designs geared towards clustered solutions
for a large enterprise.The reference to 2500 clients per server is a Cisco
recommendation using the servers that they suggest. However, it may be more
practical to use more servers for fewer clients per server. Some VoIP engineers
recommend no more than 800 clients per server just to be safe.
