This is not how this works as per my experience. A router configured for SRST will use the amount of licenses based on the configured max number of devices in the SRST configuration. It doesn’t matter if the devices are registered with the router.
That said there is no cap for the amount of devices that you can actually use in SRST in relation to the number of licenses you have. For example let’s say that you have 100 licenses, but 200 devices that require SRST services. This would work, but would of course be a breach of the licens terms.
A-flex license are subscription based and they Smart license which Cisco deposit on the Smart account you provided during the order. License will not be installed on the router.
You need to connect the router to your smart account.
normal scenario you need to connect with CSSM which cloud.
For an airgap you need to have and SSM server and connect the gateway to the SSM server.
SSM must be synced manually with CSSM.
The SRST license count reflects the total phone count for both the ephones and voice register pools that are configured in the Unified SRST irrespective of whether the phones are registered or not.
If you have 70 phones configured on one router and 70 in other you need a total of 140.
Cisco IOS XE Amsterdam 17.3.2 and Cisco IOS XE Bengaluru 17.4.1a Release Onwards
This release introduces a new paradigm for tracking license usage across your business. In earlier releases, license authorization was forward looking, binding licenses to a device until the next authorization request. Actual license usage during the proceeding reporting period is now sent to CSSM, allowing you to plan ongoing license requirements based on historical usage data. Initial device registration is no longer required to use most platform functionality and the evaluation period is deprecated.
License usage reports are submitted periodically according to a minimum reporting policy set for your account. Typically, this period could be once per year. However, you can generate reports more frequently if the use of licensed features varies over time. CSSM acknowledges each Resource Utilization Monitoring (RUM) report to ensure that the usage is recorded reliably. If the router does not receive an acknowledgment within the minimum reporting period, call processing is disabled. Call processing is resumed when a valid acknowledgment is received.
Reports can be submitted to CSSM directly or through a satellite. Cisco Smart Licensing Utility (CSLU) applications can also receive usage reports, providing you with more flexibility in managing your license usage. Also, when a device is not able to communicate directly with a licensing server, a signed usage report can be generated and manually uploaded to CSSM. The acknowledgment that is generated by CSSM must be uploaded to the device within the license reporting policy period to ensure continued use.
As license reporting is now based on historical usage, the registration process that is used previously has been replaced with a trust association that also defines the reporting policy set in your account. Establishing trust with CSSM or Cisco Smart Software Manager Satellite uses an identity token similar to earlier registrations. Use the license smart trust idtoken token command to establish the trust relationship within the initial reporting period set for the device. The CLI license smart registercommand is deprecated from this release
