Asterisk DSP
From Makers Local 256
This project will focus on improvement of the goertzel algorithm in asterisk's dsp.c. This won't be an improvement to the algorithms themselves, but more to the frequencies detectable by the code. It is currently limited to detecting US tones only which limits call progress severely. The ultimate goal of this project is to get the code submitted and into trunk so that it can go into the next major release of Asterisk.
