Is there any way I can setup an Cisco 7962 or anyother phone as a TFTP server? I know there are some IP Phones which can act as a TFTP server. Is there anyone who has done this in past or can anyone point me to cisco documentation which shows me how to do it...
The feature you are looking for is call Peer Firmware Sharing
I beleive it was added in the release of the CCM 6.x train, it is not available in any previous releases
Peer-to-Peer Image Distribution (PPID)
The Peer Firmware Sharing feature provides these advantages in high-speed campus LAN settings:
Limits congestion on TFTP transfers to centralized TFTP servers.
Eliminates the need to manually control firmware upgrades.
Reduces phone downtime during upgrades when large numbers of devices are reset simultaneously.
In most conditions, the Peer Firmware Sharing feature optimizes firmware upgrades in branch deployment scenarios over bandwidth-limited WAN links.
When the feature is enabled, it allows the phone to discover like phones on the subnet that are requesting the files that make up the firmware image and to automatically assemble transfer hierarchies on a per-file basis. The individual files that make up the firmware image get retrieved from the TFTP server by only the root phone in the hierarchy and are then rapidly transferred down the transfer hierarchy to the other phones on the subnet using TCP connections.
Configure PPID from the Phone Configuration window by using the Peer Firmware Sharing settings in the Product-Specific Configuration Layout. This menu option indicates whether the phone supports PPID. Settings include enabled or disabled (the default).
To configure the PPID feature for many phones, use the Peer Firmware Settings field in the Phone Template window of the Bulk Administration Tool. See the Cisco Unified Communications Manager Bulk Administration Guide.
