After your reboot login into that box, do your standard silly checkes….. ping by name, db replication, reverse lookup etc….
Once you shut down CM3. The phones, (I assume….. you have other cm’s in the devicepool before SRST if your using it..)) should go over to your other cm’s. At that point you should be able to call them and everything should work as expected. (Never hurts to check this while your box is down, easier then doing another outage window) My place has about 15 nodes, and thousands of end points. This happens at times with upgrade etc, TAC says its not supposed to happen, but… Hopefully that will fix it for you. If it doesn’t fix it, after 20 mins or so, you might need to get tac involved if you are not good with reading traces to figure out why. > On Jan 12, 2021, at 2:47 PM, Riley, Sean <[email protected]> wrote: > > Thanks for the quick reply.
