If you have to link your software with a GPL library or use header files
you have used GPL files and will be required to honor the license. If
you use AGI, the stdin/stdout sufficiently isolates the parts. 

An other option that is available is to negotiate a proprietary license
with Digium. Currently all code in asterisk is available to be licensed
in a form other than GPL.
