Hi All,
We are facing some registration issues in Cisco 7821 Phone. It took more than 30 Minutes to register in CUCM. Some of the Phones not getting registered with TFTP failed.
CUCM version 9.1.2. We have added the necessary device package in CUCM for 7821.
Phone Active firmware:10-1-1-9
Thanks in Advance.
