Ah, damn you're right Kristian! The data sheet http://sangoma.com/assets/docs/datasheets/en/d100.pdf contains this footnode that is omitted from the web page: "Except for AMR and AMR-WB. Integrators must clear patent license with VoiceAge Corp." :( In which case anyone obtaining licenses from VoiceAge Corp should be free to use them with any implementation... I guess this is due to the same patent pool mess Mike mentioned? -Steve On 14 January 2013 20:34, Steven Ayre <steveayre@gmail.com> wrote:

IIRC Sangoma doesn't provide licensing for AMR and AMR-WB (just the implementation).
AFAIK mod_sangoma_codec is no more legal than libamr.
