[Freeswitch-dev] Audio formats without transcoding

[seven du]

Brian,

I tested using originate  
{ignore_early_media=true,absolute_string=g729,ringback=/sounds/ 
somefile}sofia/default/1000 &bridge({ignore_early_media=true,  
ringback=/sounds/somefile,absolute_codec_string=g729}sofia/gateways/ 
xxxx/00000)

To listen the ring back, you need set ignore_early_media, the ringback  
variable maybe not needed at A-leg


To make codec g729 work, I commented one line in switch_g729_init in  
mod_g729.c:


//	codec->flags |= SWITCH_CODEC_FLAG_PASSTHROUGH;


However, I need to carefully make sure no transcoding happens,  see
