Compared to free codecs any amount of licensing is ridiculous by comparison :). On Mon, Jan 14, 2013 at 6:35 PM, Steve Underwood <steveu@coppice.org> wrote:
There isn't really anything ridiculous about the licencing of G.729. It may be annoying, but its pretty much the only encumbered codec where there is a reasonably well defined path for fairly small scale users to licence all the relevant patents (even if one or two do crawl out of the woodwork late in the day via letters from lawyers). G.723.1, AMR, AMR-WB, EVRC, GSM-HR, GSM-EFR, etc., are all a PITA to licence.

My understanding is that AMR licensing is even more ridiculous than G729.

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?

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