As part of my lab-work (roaming project), compiled SILK and AMR codecs for Asterisk. Will publish instructions –- currently newly compiled codecs are on stress test. Who wants to build prior my post could try, I was use this repository: github.com/mordak/codec_silk.

Have little issues with AMR-NB, will post update later.
