Is there a decent URL (I have not found one yet) where the dependencies of each of the Call Manager products is detailed. I ask this as I have several systems on 3.0(11) with Ver 2.1 eServices and AA, ICD, BATS-TAPS configured but when I upgraded the CM to 3.1 these all stopped working , The only solution I had was to upgrade to CRA 2.2 and BAT 4.2. I also had to upgrade all the ICD clients.
Did I do something else wrong or are they truly incompatible.
