Hi Richard,
From a post in another thread:
Q:
"Are there any Cisco or other tools available which would allow me to simulate agent logins so I could test how many calls per second my system can actually support."
A:
"You can use ciltest to emulate agents. I believe it is on the CTIOS CD under Tools\ClientTest."
