Hi, I have 7960G with P0S3-07-5-00 firmware. I can not get to menu because I get "Protocol Application Invalid" When I track down communication with Ethereal I see that IP phone is sending requests from 255.255.255.255 IP address which is strange. If I reset the phone ( * + 6 + Settings ) it does not reset the IP address. Is there any factory default reset? Hopefully my phone didn't become a brick.
Additionally I found this in Cisco Bug Tool My problem(bug) is probably below, but I didn't input the
255.255.255.255 there but looks like the same behavior.------------------------------------------------ bug CSCeg55180
Symptom : On a Cisco 7960 Phone, the IP Address of the phone may be manually configured with certain illegal values. These values include the following ranges:
127.0.0.0 through 127.255.255.255 - the IP Loopback address 224.0.0.0 through 255.255.255.255 - Multicast and Class E Address rangeConditions: DHCP is disabled, and address is entered via the IP Address item on Network Settings menu.
Workaround: None.

Thank you for any ideas. Lada
