I want to order cisco ip phone(cp-7942G), 50 qty, i was told to install a call manager RTU license before this order can go through from the configuration tool(DCT). though we have some call manager and servers like MCS-7825-I4-IPC1 and MCS-7845-I3-CCE1 coming with this order.
which option of license should i select for the IP phone:
(a) SW-CCM-UL-7942 CUCM 3.x or 4.x RTU license for single IP Phone 7942
(b) SW-CCME-UL-7942 Communication manager express license for one 7942g phone
please which license should i select?
