firmware update via config file
I'm unable to get a T2x to upgrade firmware via the config file -
firmware.url = tftp://xxx.xxx.xxx.xxx/9.71.193.6.rom
Same with HTTP.

I've tried T20, T26 and T28

The tftp server logs show the phone pulling the file blocks successfully, but it never upgrades successfully.

It pulls the same file fine from a PC when entered in the GUI.

Does this work for anyone? Ideas?

RE: firmware update via config file
Hi jdackert,

Can you tell me the current version of your phones?
Do you mean that you can upgarde them via webpage?
Please don't forget to add #!version:1.0.0.1 to your syntax.
---------------------------------------------------------
#!version:1.0.0.1

##File header "#!version:1.0.0.1" can not be edited or deleted, and must be placed in the first line.##
firmware.url = tftp://xxx.xxx.xxx.xxx/9.71.193.6.rom
---------------------------------------------------------

RE: firmware update via config file
#!version:1.0.0.1 is the first line of the config file.

I recently tried from 2.72.0.25, 9.71.0.140 and 9.72.0.1

They do upgrade from webpage. I'd like to be able to upgrade phones at customer sites where I don't have GUI access to NAT'ed phones.

RE: firmware update via config file
I found the problem - My tftp server was timing out the connection.
It works on a different tftp server

RE: firmware update via config file
The failure occurs because neither side resends the last Data (server) or ACK (Yealink) as suggested in the tftp RFC.
