| I'm wondering if stopping the CCM service is enough of a test. Could there perhaps be another service that the SRST router is connecting to?
I don't see how the SRST router and phones can continue to operate after a reboot if connectivity to the cluster is lost.

I did a little afternoon testing on this power cycle question I had.
I registered a 7960 running FW 7.2(2) to CCM in my lab and then
stopped the CCM service. The phone successfully failed over to my
SRST 3.3 router.
Then I power cycled the SRST router and when the router came back
online the phone registered back to SRST with the correct DN.
Rebooted the phone and it still reregistered with the correct DN.
It even registered back to SRST with the correct DN after power
cycling the phone and SRST router at the same time.
I then power cycled the router and did a factory reset procedure on
the 7960, choosing to save the network config during the process.
After the phone reset it registered back to the SRST router but
without any DN.
So the phone must save the most recent DN somewhere in flash and
retains this even through power failure.
I did not test this with EM.
