Right.

However This is incorrect: '!' only works in a remote asterisk terminal: 
a connection from a different process (on the same system) to the running
Asterisk process.

It will run a subshell of thatremote process. So it is not necessarily
related to the environment of the Asterisk process.

Also: when running something in System(), note that you run a
subprocess, and that this subprocess may have its own separate
environment.
