[cisco-voip] Phone Load update - phones do not upgrade

[Wes Sisk]

Either:
1. phones are not resolving proper tftp server
2. tftp server is not service correct data
3. config is incorrect for TFTP config file

to verify:
1. browse to phone's ip address, check TFTP server listed there.  if 
TFTP server is properly listed there security can still intervene. If 
you have cluster security enabled is the specified TFTP server included 
as a TFTP server in CTL configuration?  Form the phone LCD you can view 
the contents of the CTL file to confirm what TFTP servers are valid for 
the current security configuration.

2. TFTP could have been busy still building config files.  Check 
performance counters through RTMT for:
Cisco TFTP
 Reqeusts Aborted
 Requests Overflow

If those show large values it is likely that TFTP was still busy 
building config files and not ready to service requests.  Next if you do 
not encrypted config files enabled you can attempt a TFTP download to 
confirm behavior.  From windows command prompt:
C:\Temp>tftp -i 14.48.40.57 get XMLDefault.cnf.xml
Transfer successful: 6425 bytes in 1 second, 6425 bytes/s

C:\Temp>notepad XMLDefault.cnf.xml
For example on my cluster for 7961 the default load is:
<snip>
<loadInformation30018  model="Cisco 
7961">SCCP41.8-4-3S</loadInformation30018>
</snip>

This is the global config applied under device->device settings->device 
defaults.



3. Next is the phone specific configuration.  Phone specific 
configuration overrides global configuration.  On the phone 
configuration page in ccmadmin you can specify "load information" per 
phone.  If this is specified it takes precedence over the global 
option.  Check the configuration in CCMAdmin or check the phone config 
file directly.  Example from windows command prompt:
C:\Temp>tftp -i 14.48.40.57 get SEP001bd5846d80.cnf.xml
Transfer successful: 7315 bytes in 1 second, 7315 bytes/s

C:\Temp>notepad SEP001bd5846d80.cnf.xml
<snip>
<loadInformation>SCCP41.8-4-3S</loadInformation>
</snip>
