Hi X-man,
thanks for your reply.
With this step i don't have the way to restore defaults.
After Hold both volume up\down for 4 second the phone display??
I have a Ip 5207, but after 4 second show only "MAC Address 08:00:0F:....." and after USING STATIC SETTINGS.
No other information display.
If press up volume for about 4 second i can set a static IP, but i don't understand how to restore default!
Thanks!
Steve
