Does "telephony-service" and everything you have configured under it just disappear? Does it stay in the config but stop working and phones no longer register? If something bad happens after the 8 weeks is up do you need to buy some sort of physical license file that needs to be installed on the flash and activated, thus opening back up the "telephony-service" function, if it does disappear or cease to work? It seems the only thing that triggered this event of the 8 week timer was the provisioning of "telephony-service". More specifically, (CME 8.6) when you enable "telephony-service" on a base router that has uc9, the router then asks you to "agree" to use, and after you do, an 8 week timer starts on some kind of "CME-SRST" built in trial license/feature/whatever you call it. What happens after the 8 weeks, exactly? No one can answer this.

Then you need the CME licenses you listed to allow endpoint registration, these licenses don't get applied you just need to accept user agreement on router.
