I´m performing a fresh install to a CUCM 11.5 (the old version of CUCM is 8.6.2). I´m performing a some IP Phone test (firmware download, locale, etc) before updating and I modified the TFTP manually in each telephone to the IP of the new CUCM. I have problems with the Trust List.
- This problem is due to I modified manually the TFTP ?
- This problem is solved using DHCP option 150 with the IP of new CUCM?
- How to check this before the date of migration to CUCM 11.5?
