Yealink W52P ResetBase -> UserAgent Empty

[antonio3ds]

Hello

I'm testing auto-provisioned phone Yealink w52p.

When I do the factory reset the device loses its user agent and as a result I can not make it compatible with my application.

I also noticed that during auto-provisioning does not install the firmware retrieves settings that I previously exported from the device.

The firmware that I have tested are:

- 25.30.0.20.rom
- 25.30.0.26.rom

If you install the firmware manually the device recovers its UserAgent and it works, but if you change firmware.

I await your feed as soon as possible.
