[cisco-voip] "File Not Found" When Upgrading to 7.1.2

[Wes Sisk]

So that leaves the TFTPServer and interim network

maybe TFTP server on CM is non responsive.  w2k has a builtin tftp 
client convenient for testing.  from cmd line:

C:\>tftp localhost get xmldefault.cnf.xml
Transfer successful: 2316 bytes in 1 second, 2316 bytes/s

Then for the extra paranoid like myself, verify the downloaded file is 
the same as the server file in the TFTPPath directory by using md5sum.  
A windows version is available here:
http://www.etree.org/md5com.html

compare the md5sum of the downloaded file and the original file.

If md5sums match, I suspect something in the network is interrupting the 
TFTP stream.  Our phones have a tenuous relationship with firewalls when 
it comes to TFTP.  the UDP port selection for tftp goes like this:

phone:RandomUDPPort --> tftp get --> TFTPserver:69
phone:RandomUDPPort <-- tftp data packet#1 <-- TFTPserver:RandomPortNumber
phone:RandomUDPPort --> tftp ack packet#1 --> TFTPServerRandomPortNumber

step 3 is where most firewalls draw the line because of the 2 random 
port numbers.
