! Voice Activity Detection – Enables or disables the use of Voice
Activity Detection (VAD). When the VAD algorithm is enabled,
silence intervals are identified. Therefore, only relevant information
is transmitted, using less bandwidth than during voice activity
intervals. This allows for a better overall utilization of the available
bandwidth. Voice Activity Detection is not applicable when using the
G711 codec. Voice Activity Detection is implemented automatically
in G729wAnnexB and G729 Annex A w Annex B (Annex B activates
the silence compression).
Available options are:
" Voice Activity Detection OFF.
" Voice Activity Detection G7231 (enable when using G723.1
compression).
The default selection is Voice Activity Detection OFF.

! Output (D/A) Gain - Applicable only to SU with voice HW version D
