We have a CS1000 Release 5. We had a new UPS installed over the weekend, which cut power to our networking equipment and reuqired shutting down the signaling servers (the PBX was left up and running).
All of our phones that were registered with the signaling servers before the UPS install are fine, but any phone we move or reboot fails to come up properly.
The phone boots normally until it shows the TN. After selecting "OK" to confirm the TN, the phone display goes blank.
If I hit the left-most soft-button at the bottom of the display, the phone asks for the TN again, then immediately goes blank after confirming it.
Any ideas as to what could be causing this? Again, phones that are already registered are working fine.
Thanks for any help!
