Hi,

I have an issue where calls on Freeswitch hangup when using DTMF (i.e. ) interactive touch tone services. I traced the log while this was happening and it looks like an error in switch_core_media.c  where it can't load a particular codec and appears to hangup. Does anyone have any suggestions on how to fix this? Log trace at http://pastebin.com/Ua7ji1fk


Thanks
