i have 3 7845 CUCM appliances that will serve about 3000 phones. I'd like to know which could be the best services distribution across the 3 appliances.
I have a multisite with centralized call processing and I will create 1 Publisher and 2 Subscribers that will load balance calls through 2 CM groups.
For TFTP, i think i will use the Publisher as primary and 1 Subscriber as secondary (i don't know if is the best choice..)
My doubt is about additional services and which one is the most processor intensive:
- Conference (i have no additional hardware for conferencing, so i use CUCM software)
Which could be the best distribution for the 3 services above ? (and for TFTP also...)
