RE: Upgrade firmware error from tftp boot server
From the syslog, we can know that the phone can't download the firmware from the server, so the phone can't upgrade to new version.

Suggest that you can check the server or change other server then test again.
And why do you need to upgrade to 9.73.193.50.
This is a Broadsoft version, if you don't use the Broadsoft PBX, please don't upgrade to this version.
