Dear all,
I have a customer, where he has 270 soft-phones and 30 hard phones in India registering to a Call-Manager installed in US.
Also he has 2 number of MCS7825I2-K9-CMA2 (CUCM 5.1) and another 2 number of MCS7825I2-K9-ECS1 (Unity) which are bought years back and not installed for some reasons.
Now he wants to upgrade his CUCM 5.1 to the latest version i.e. CUCM 8.0 or 8.5, and make all phones in India to register to this CUCM.
MCS7825I2-K9-CMA2 is under smartnet coverage, but he has no UCSS.
As per my understanding he should be able to upgrade software version 5.1 to 8.0. Can you please confirm?
What is the upgrade part-numbers that he should buy?
Your suggestions will really help.
Tks,
Raghavendra
