Allows the phone to find other phones of the same model on
the subnet and share updated firmware files. If the phone has
a new firmware load, it can share that load with the other
phones. If one of the other phones has a new firmware load,
the phone can download the firmware from the other phone,
instead of from the TFTP server.
Peer firmware sharing:
•
Limits congestion on TFTP transfers to centralized
remove TFTP servers.
•
Eliminates the need to manually control firmware
upgrades.
•
Reduces phone downtime during upgrades when large
numbers of phones are reset simultaneously.
•
Helps with firmware upgrades in branch or remote office
deployment scenarios that run over bandwidth-limited
WAN links.
