[cisco-voip] ITL and TVS question - CUCM 8.5.1.14048-1 and Secure URLs not working (corp dir, etc)

[Jason Burns]

Erick,

Did you also migrate to new hardware and use the backup and restore (DRS)
process during the upgrade?

If so, you might be running into the following condition / defect. Give
this a read and check it out.

If you're sure that none of the phones have ITL files installed then it is
safe to regenerate the CallManager.pem certificate and restart TVS, TFTP,
and CallManager (in that order) to resolve this problem if you can confirm
you're running into it.
