[Freeswitch-users] Codec G.729 encoder error

Tue Aug 11 14:01:34 MSD 2015

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)
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)
