<DIV><BR></DIV>I did a little afternoon testing on this power cycle question I
had.<BR><BR>I registered a 7960 running FW 7.2(2) to CCM in my lab and
then<BR>stopped the CCM service. The phone successfully failed over to
my<BR>SRST 3.3 router.<BR><BR>Then I power cycled the SRST router and when the
router came back<BR>online the phone registered back to SRST with the correct
DN.<BR>Rebooted the phone and it still reregistered with the correct
DN.<BR><BR>It even registered back to SRST with the correct DN after
power<BR>cycling the phone and SRST router at the same time.<BR><BR>I then
power cycled the router and did a factory reset procedure on<BR>the 7960,
choosing to save the network config during the process.<BR>After the phone
reset it registered back to the SRST router but<BR>without any DN.<BR><BR>So
the phone must save the most recent DN somewhere in flash and<BR>retains this
even through power failure.<BR><BR>I did not test this with
EM.<BR><BR>Justin<BR><BR><BR><BR><BR>On 6/28/06, Ryan Ratliff <<A
