We currenly have two 7825 (I think H2's) and two newer HP servers in our test lab and are looking to run Presence, Unity, and possibly Personal Communicator on a single server. We already have dedicated servers for CUCM.
1. Can two (or all 3) of Presence, Unity, and CUPC be run on one server?
If "yes" to #1, then
2. What are the server requirements to do this (and can the 7825's accomplish this)?
3. Are there any special rules or version requirements to run multiple apps on one server vs. on dedicated servers?
