If I can remember correctly, mod_g723_1 is a passthru codec. So in other words, transcoding will not work at all

Hi,
   I am currently working on freeswitch-1.2.12 version. how can i convert wav to G723 format using fs_encode binary.
   After installing the module mod_g729_1, I run the command as follows

    "./fs_encode -l mod_g723_1 temp.PCMU temp.G723"
then it is raising the error as " Couldn't initialize codec for G723@8000h@20i ".
Thanks in advance.
