You may see the phone-home related syslog even when there's no phone-home client configuration in place.

If you look at the syslog generated before and after the time that phone-home related logs generated, you may see that process mgd is calling several other child processes, along with the phone-home process.

All those child processes was called due to the command "show version detail" command. To get the version information of all software components, mgd executed all other software processes and that's why many child processes were executed and exited at the same time. While the child process "phone-home" was also called just for retrieving the version information, it does some system information gathering when being executed, which is the reason why phone-home related syslog was seen on the system.
