I've a customer with a 2821 CME and the AIM-CUE with installed a CUE 7.1.5 and no contract support. Now he want to convert the CME to SRST and use the AIM-CUE with the CUCM 8.5 that he already own. I've checked the compatibility matrix and i found that i can install the CUE 7.3 that it work with the CUCM 8.5.
My problem it's about the licenses. I'm not able to find in the ordering guide if it is possible to buy the upgrade from CUE 7.1.5 to 7.3 and what product-number are needed for that upgrade. There is someone who know about that question?
