So this number of agents is actually the capacity of each CC? like how 
many simultaneous calls the CC can handle.

Have you looked at the load_balancer module ? 
(http://www.opensips.org/pmwiki.php?n=Resources.DocsTutLoadbalancing)

you can define the size of each CC in the DB and also change it at 
runtime (see the MI commands)

If you need some help on this, please let me know.
