Officially: nowhere, they seem to be under an NDA. There was a post 
stating the commands from a user under [1].

Very likely, yes.

The only thing I know about it is 'Enable AEC and Noise reduction', 
which is the response you get from the phone if you send the command.

As OM currently does not seem to have the resources (or motivation as 
there are more pressing problems) to improve the echo situation it 
maybe useful if someone from the community could sign an NDA with TI. 
Maybe OM could help on this front (establishing communication with TI)?
