<pre wrap="">I'm going to retract my earlier statements.
After shutting down the CallManagers completely, the 7960 (FW 7.22)
phone does not register back to SRST router after power cycling the
phone.
Perhaps the phone needs to TFTP from the CCM before it can register to
the SRST router.
This seems like a limitation of SRST. I can see a bad storm knocking
out a T1 line and commercial power.
Is there something I'm missing or is the answer to have a PoE switch
and a SRST router on a UPS?

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.

This isn't specific to EM. But what happens if you are operating in
SRST mode and you lose power to all the phones and the SRST router.
Do the phones or router keep record of their last DN in flash or would
you be completely down after power came back with access to the CM
cluster still unavailable.

I just tested with a 7970 and when the phone drops into SRST mode it
keeps the EM profile dn(s). Since you don't configure ephone/dns in
SRST the phone keeps whatever dns it had before it unregistered
with CM.

<pre wrap="">Hi Ryan,
i am sorry that i didn't clarify it but i was
refering to the situation
where there is an SRST involved:
there is a CCM cluster and an SRST configured at the
Device Pool to the
remote site.
At the remote site a user logs in with EM but at the
USER device profile
there is no reference about the device pool.
What happens to that phone while it is logged in
with EM and the remote
site loses connectivity with all the CCM cluster?
Cheers
Anthony
