Subject: Re: [Freeswitch-users] Codec G.729 encoder error

2015-08-11 14:32:28.827339 [ERR] mod_g729.c:102 This codec is only usable in passthrough mode!
2015-08-11 14:32:28.827339 [ERR] switch_core_io.c:1423 Codec G.729 encoder error!

You're trying to use mod_g729 to do transcoding (converting between different codecs, which includes playing a file). However that module is the version that doesn't require a license and thus can only act in passthrough mode where it transfers data between call legs that's already converted to G729. It cannot encode or decode, hence the error when you try to play your WAV file.

Your options are:
1) Use mod_com_g729, which is the licensed version and supports transcoding (see freeswitch.org<http://freeswitch.org>)
2) Try using a codec other than G729 (perhaps the codec choice of the client is not in your control though)
3) See whether mod_native_file can playback the file already converted to G729 (you'll still need a license for the conversion though, and still hit transcoding errors at other times eg during a bridge)
