TFTP connecting but config not updating

[Darren.Jordaan]

Hi, I'm attempting to set up auto provisioning via TFTP for a T20P running Firmware 9.70.0.140. Wireshark trace shows the phone submitting the TFTP read request and the correct y000000000007.cfg file however none of the parameters are updating on the phone. To simplify troubleshooting I removed all parameters except for the Auto pProvisioning and Time Settings parameters. My minimized config file is shown below as well as attached [/code][/quote]and I'd really appreciate any help:

#!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.##
