Hello, can we change the TFTP server address on a cisco 79xx phone remotely?
I know we can use the SEP<mac>.cnf file to configure, but can we also change the TFTP address using this file. The problem we have is we are changing the IP of our SBC and it requires the TFTP server to be configured on all the customers' phone. Instead we are planning to host a new SBC on the new IP address and push the configuration with new TFTP address to all phones, so when the phone reboots, it gets the configuration using the new SBC (which will forward the requests to the call manager). Please note we are not using Cisco Call Manager.
