UCL Licensing and mix of MCS server

Hi all,

i'm working on a solution for a customer where there is a central server farm and more remote sites.

In the server farm we are going to provide two MCS7845 (Publisher+Subscriber) while the small remote sites (from 10 to 30 users) will have a local VG with SRST. There are five big remote sites that need more attention for the backup solution, for these sites we would to provide a local MCS7825 and a local VG. My question is about the licensing and the part number i need to purchase: for the server i use those part number MCS7845I3-K9-CMD1 and MCS7825I4-K9-CMD1, for the call controll part number what i need to provide?

7 x UCM-7845-80 or

2 x UCM-7845-80 + 5 x UCM-7825-80?

The configuration tool don't let me choose a mix of call controll part-number.
