i have 2 5530e phones that are giving me issues. when i put on the icp address and use the same address for the tftp server i get connected to the 5000 and then it doest and upgrade and then reboots and the cycle begins again. i take the tftp out and nothing happens even if i give the phone an ip address, gateway and subnet mask. i took out the ip address, gateway subnet mask and changed the tftp server address to a made up address like my modem ip address.... it worked but it says tftp unavailable. what do people use normally for there tftp server address and how come it keeps updating software on the phone and never gets anywhere?
