| SRND states the goal of SRST is WAN link failure.
I've seen this debated about whether it works or not, phones in parts of
Africa lose the T1 and the power, and don't register under SRST when
power is restored.

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?
