SIP-T20P Old Firmware doesnt upgrade in auto provisioning

[JamesK]

for the firmware we using ftp instead of http. we have really great success with that.
when we do ftp there is only 1 line needed in the configuration file that way as well. it looks like this:

"ftp://userid:password@ftp.location.com/foldername/foldername/filename.xxx"

obviously you can use an ip address instead of the "ftp.location.xxx"
you can go several folders deep as well.
you can even use something like 2cdaemon to use as your ftp server if needed.
