SMART Licenses - SRST

I have opened a ticket with Cisco but I want some input from the community. I have deployed ISR4331 routers. When I do SMART Licensing, it applies 110 SRST License which is the max that the router can do.  I have several sites that have a lot fewer licenses, such as 40 or 50 licenses, so I don't need to apply all of these licenses. If I do then I run out of SRST licenses.  For example, I have 24 ISR4331 routers, so if I use 110 at each site then I would need 2640 licenses and I only have about 1550 SRST licenses to cover the actual phones I have.

 

I was told by Cisco that SRST licenses are counted as the sum of the max-pool (under voice register global) and max-ephones (under telephony-service). Also I have some schools that use SCCP and some that use SIP. So if I have school that has 50 phones, I want to use 50 SRST license (not 100 or 110). What is the solution to get the correct number of licenses for a school? Does the solution change on whether it is a SIP or SCCP site?

 

A snippet of the config:

Re: SMART Licenses - SRST

As per the guide it is just upper license limit. You can purchase the required number of SRST licenses and register in Smart Account. No

The license limit on Unified SRST is restricted by the maximum platform limit defined for the Unified SRST router (a cumulative sum of phones configured under max-pool and max-ephone).
