7821 Registration issue

[gpsriramdc]

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.

Hi Ajith,

In our case some of the phones are registered & partial phones are having the problem. CUCM configuration , TFTP Server , Voice VLAN everything is identical as same as working phone.

But in the Phone configuration i couldn't see the UCM IP Address.

Thanks Nagarajan.

We have resolved this by upgrading CUCM to ES version for the specific bugfix.
