I have set up autoprovisioning with PnP on the snom one and this works fine with the Snom 720s (using 4.5.0.1090 Epsilon Geminids (Win32)) Firmware on the phones is 8.7.2.9. When I upgrade the firmware to 8.7.3.10 PnP stops working. I cant even register a phone running 8.7.3.10 to the switch using PnP I have had to downgrade the phones to the old firmware to do this.
I am also trying to get buttons working on these phones, they work on the new firmware but not the old so I am stuck, do I upgrade the firmware and lose PnP or keep PnP but lose the buttons...
