Transcoding happens automatically when the legs are using different codecs.

disable-transcoding modifies the bleg codecs so it only offers the same codec as the aleg has selected from the options, so that transcoding is not required. You don't need the option.

Are you using mod_g729 or mod_com_g729? Only mod_com_g729 supports transcoding (assuming you don't have a hardware transcoding card).

Perhaps you could share the debug-level logs? They'll contain some information on the codec negotiation.

Everything seems to work except transcoding between extensions. 

Looking at the docs I can only find the value of disable-transcoding which can be set to true. This seems as quite the opposite. 

Where can I allow FS to automatically transcode if 2 extensions (client and sip trunk) speaks different codecs?

Yes, you only need to turn on transcoding and put at the beginning the codec on the codec string

I've got FreeSWITCH running and works really well.

I would like to use G729 as codec whenever possible.

My SIP Trunk does not support G729, only G711.

My apps which are connecting to my FreeSWITCH are supporting G729, license has been paid for these.

Can I setup FreeSWITCH to use G729 whenever possible, and for SIP Trunks conversion happens, such as:

app/G729 <> FS <> app/G729

app/G729 <> FS <> SIP Trunk/G711
