I just have two quick questions about updating the firmware/phone load on UCCM 6.1.2. We have a 3-server UCCM cluster; 1 Pub & 2 Subs. We are using the two Subs as primary TFTP servers and the Pub as TFTP backup for all IP phones.
Is it necessary to update each TFTP server with the new phone load before the Load Information shows updated under Device Defaults Configuration? I ask this because my Load Information on each Sub did not update after installing the newest IP phone firmware file and restarting TFTP services.
When I attempt to install the firmware file on the Pub, I get "Error on Page" in the lower left corner of the browser just as I click the NEXT button after entering the FTP server info on the Software Installation/Upgrade page. I'm using IE7 and do not have this issue with any other UCCM servers in the cluster. Has anyone else experienced this symptom?
The short answer to your questions 1 is Yes
The release notes for any phone release states
Installing Firmware for the Cisco Unified IP Phone (SCCP)
Before using the Cisco Unified IP Phone with Cisco CallManager release 3.3 or later, you must install the latest firmware on all Cisco Unified Communications Manager servers in the cluster.
Also make sure you have the appropriate device pack.
As for question 2 sorry not seen this before have you tried re-accepting the certificate
