I suggest you discuss this with a local Cisco partner with UC specializations, and explain your needs, goals, future growth, etc. So they can propose the best solution based on your requirements.

Hi,

You can deploy it as CME but not as CUCM unless you get UCS-E card to
deploy CUCM on ISR4k. For the number of phones listed, here is the sizing
table.
