Hi ,

That command is used to define the IP address(es) of the TFTP server(s) (CME/CUCM) to download the phone configuration files.

Option 150 is the TFTP server IP  provided by the DHCP pools in the DHCP servers.

These are used by the IP phones to get the information of the TFTP servers from where it can download required configurations.

Cisco IP phones find the required TFTP server through the DHCP option 150

Option 150 is a DHCP option used to define the IP address of the TFTP server from which IP Phones then download the configuration files.
