recording to .wav is ok but to .ogg, FS reports:

2013-06-19 20:24:34.993063 [ERR] switch_core_file.c:150 Invalid file format [ogg] for 

[D:/recordings/1006_11500_20130619202434.ogg]!

2013-06-19 20:24:34.993063 [ERR] switch_ivr_async.c:2004 Error opening D:/recordings/1006_11500_20130619202434.ogg

is there any additional mod required for .ogg, just like mod_shout is needed for .mp3?
