I have a customer who is relocating their CUCM servers to a data centre, and wants to upgrade their existing C2921-VSEC/K9 with SRST. When I use the Dynamic Configurator to generate a parts list, I end up with the following additional parts:
Cisco Survivable Remote Site Telephony License
Communication Manager Express or SRST - 5 seat license
The part number L-FL-CME-SRST-5= exists, but it seems to me I should have to add the SRST "application" to the router - can I just add the licenses to the router and have it work?
