I have IP 7940 phones connected to an IP PBX. After the IP-PBX configuration was done, i plugged in the 7940 phone to get it on track, but unfortunately it didn't work. Now i see on the ip phone screen "TFTP timeout" and all the buttons are kind of frozen. So i tried to reset it to the default conifguration by rebooting and hold down on "#"..., and it didn't work too.
Basically the phone is not working at all, and i'm a little bit concerned and i don't know how to make work///
