With the Connect Now CNipIT, you can have as many users/agents as you would like. 

For display purposes, a maximum of 6 user images will populate the CNipIT at one time if more than 6 users are set to "available" the first 6 images will appear with the number 6+ Agents Available. All agents available will have an equal opportunity to claim incoming leads (subject to any Lead Routings you have set).
