Hello All,
Has anyone experienced issue with 7905G and 7912G phones on CUCM 10.5x. It seems that when the system goes down and comes back up, the 7905G's and 7912G's stay stuck at "Configuring CM List". There was an issue with the network where the nexus had a processor failure. Once the phones came back online only the 7905's and 7912's did not re-register. We needed to manually walk around and reset the 7912 and 7905 phones. Has anyone experienced similar issues?
Thanks

Hi
Sorry the delay. Those two models 7905 and 7912 are in End of support for several year, so the problem is with firmware for those guys, which is not supported by these newer CUCM release. So that's why you're getting problems.
If you take a look on Cisco Collaboration Systems Release Summary Matrix for IP Telephony you will see that both phones does not show anymore

How many phones do you have?
Thanks
