how many gateway can 3600 router support as a gatekeeper

[admin_2]

I like to check how many gateways a Cisco 3640 can support as a H.323 gatekeeper. Is there a difference in the number for Cisco (AS5300) and Non-Cisco gateways?

Cisco is recommending 100 registered endpoints per gk ( no difference between endpoints),

it's based upon a desired call/second rate of 80 cps. The basic concept is that as you increase the number of supported endpoints, the performance

in calls/second will decrease.
