And the only thing g726tog726aal2_framein does is changing order of these nibbles. So in theory g726tog726aal2_framein + g726aal2tolin_framein should be indistinguishable from g726tolin_framein. If it is not true, it can indicate a problem with the whole transcoding core not just with this particular codec. This is why I believe it is good idea to investigate.
