[cisco-voip] Cisco phones trying to TFTP file ending in TLVextension

[Wes Sisk]

If you are on CM 3.x running 7.0 or 7.1 phone loads, the phone must receive
the TFTP File Not Found response from the TFTP server, otherwise it will
abort.  I recently encountered an issue with the PIX FWSM blocking this
message and preventing phones from upgrading CSCef67634.

Could this be contributing to issues with phoneload
upgrades not taking?
