[cisco-voip] Testing phone firmware updates prior to rollout.

[Robben, John]

Can anyone share a method for testing phone firmware on a limited set of
phones?

I've installed a TAC recommended firmware update in CUCM 7.0 per the
readme, but now TAC tells me that once I restart the TFTP service, all
phones in the organization will begin downloading the updated firmware.

Thanks in advance.
