[cisco-voip] IPCCX Agent Licensing ?

[Dane]

Can someone confirm if the agent licensing for IPCCX is based on the
number of agents logged in at one time or the number of agents you
will install the software (CAD) on?

For instance, if you have 40 possible agents but only 20 are ever
logged in at the same time (shift work).  Do you need 40 agent
licenses or just 20 for the max ever logged in at same time?

I ask the group because I don't always trust my sales reps when it
comes to licensing.
