g711u Codec Enable
The ITU-T G.711 with mu-law standard codec
that uses Pulse Code Modulation (PCM) to
produce a 64 Kbps high-quality voice data
stream. This standard is used in North
America and Japan.
Enable
Enable/disable
g711u Priority
The priority of codec by which the unit will
attempt to use for best voice quality
Fourth
priority
g711u ptime
Set the time (in miliseconds ) for the unit to
attempt to use the codec highest priority in the
list before trying the next lower one.

g711a Codec Enable
(G711.aLaw): The ITU-T G.711 with A-law
standard codec that uses Pulse Code
Modulation (PCM) to produce a 64 Kbps
high-quality voice data stream. This standard
is used in Europe and most other countries
around the world.

g711a Priority
The priority of codec by which the unit will
attempt to use for best voice quality
Third
priority
g711a ptime
Set the time (in miliseconds ) for the unit to
attempt to use the codec highest priority in the
list before trying the next lower one.

g729 Codec Enable
The ITU-T G.729ab standard codec that uses
Conjugate Structure Algebraic-Code Excited
Linear Prediction (CS-ACELP) with silence
suppression to produce a low-bandwidth data
stream of 8 Kbps. Note that DTMF and fax
tones do not transport reliably with this codec,
it is better to use G.711 for these signals.
