hi, everyone. anyone knows how I can make my ip phone working again? after i made a factory reset on it, the screen show only three words, the ip address, mac-address, and a big word CISCO below it.,i already tried doing the 3491672850*#, but it wont work, and now the biggest problem is, there is no characters shown in the screen, but still it can get an ip address from a dhcp address. the version shown in the router is "79xx_default_loads" goes something like that. working on this couple of days already, been trying all the troubleshooting tecniques i found on the net. Thank you.
