I have a Cisco 7912G phone with SCCP ver 1.03 and I tried to load SIP 8.01 then SIP 1.01 via TFTP but it's not working. While I am able to go into the Network Configuration and specify the TFTP IP Address, IP Address and other functions when I save and reboot the phone it just goes off into an endless loop of searching for previous CallManager IP 10.24.97.1>Configuring VLAN>Configuring IP via DHCP> Repeat. The only thing that gets transferred via TFTP is the "gkdefault.cfg" file. I would see in status messages on the phone that TFTP times out even though the TFTP Address and, Laptop IP is correct and I turned off the firewall.
