I found the following table in some dated Lync material. Half the time Lync is referred to as OCS Wave 14 so I hope this data is still relevant. I have never seen this table before so I thought I would share it. It lists what the limits are for various response group scenarios for Enterprise Edition or Standard Edition pools.
|Per EE pool (with 8 FE servers)||Per SE server|
|Incoming call per second||16||2|
|Concurrent calls connected to IVR or Music on Hold||480||60|
|Concurrent anonymous sessions (without IM)||224||28|
|Concurrent anonymous sessions (with IM)||64||8|
|Active agents (formal and informal)||1200||1200|
|Number of hunt groups||400||400|
|Number of IVR groups (use speech recognition)||200||200|
Can anyone confirm if this data is still valid?
