It "feels" very expensive. Part of it is because of starting a new
instance of Asterisk. It will not load any module and such, but if you
care about speed, you can use netcat (it takes some care).

You'll also encounter some artificial delays in the response which make
it feel more expensive.

The main reason to avoid it is because its output is not intended for
automated parsing.
