You answer your self in this last sentence. You don't plan to distribute
so you don't have to open source. 

Alternatively, the stdin/stdout of AGI insulates you from the GPL as you
no longer are linking against the asterisk sources. What you are linking
against is the libraries of your compiler/interpreter and most if not
all of them are licensed in such a way as to not interfere with your
software license of choice.
