AVM support answered: g711-HD is g711 A-Law sampled with 16 kHz.

Currently AVM does not have intentions to support Siren7, Siren14, SILK 
or CELT in the near future, they will stick to g722 and (g711-HD between 
their own devices with double the bandwidth of g722 when this is readily 
available).

Still I am curious: What exactly is braindead about it?
