[Freeswitch-users] mod_amr transcoing for testing purposes

[Steve Underwood]

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.

Regards,
Steve
