I am very new to IP VoIP, and I am starting to have an issue with my 7911 and 7961 phones not booting up. These are phones that were active and just stopped working. When I try to power them up using either POE or a power adapter, they will flash some lights and then nothing. The display never comes up or anything. I tried to do a factory reset but when I type in the 12345678*9# sequence, the lights immediately stop flashing and the phone does nothing. Has anyone ever dealt with this issue before. Currenlty I have 4 phones doing this and I have no spares left to pull from. Any help would be appreciated!
