[cisco-voip] Centralized TFTP and Auto Registration

[Jason Burns]

I think auto registration is specifically addressed in the documentation
regarding centralized TFTP. The two can't be used together.

I love the System Guide!

When phones are configured in a Cisco Unified Communications Manager other
than the cluster where the master TFTP server is configured, and
auto-registration is enabled, and the off-cluster Cisco Unified
Communications Manager goes down, if the phones are configured to submit a
request from the centralized TFTP server, they may inadvertently get
auto-registered on the central Cisco Unified Communications Manager.
Therefore, you should disable auto-registration if it is not already
disabled or delete the inadvertently registered phone after making sure
that the cluster to which it belongs is up and running.
