This table holds the parameters that define the
codecs used.
          
PCMA and PCMU are specified in ITU-T Recommendation G.711. Audio
data is encoded as eight bits per sample, after logarithmic
scaling. PCMU denotes mu-law scaling, PCMA A-law scaling.
          
G723.1 is specified in ITU Recommendation G.723.1, Dual-rate speech
coder for multimedia communications transmitting at 5.3 and 6.3
kbit/s. This Recommendation specifies a coded representation that can
be used for compressing the speech signal component of multi-media
services at a very low bit rate. Audio is encoded in 30 ms frames.
A G.723.1 frame can be one of three sizes: 24 octets (6.3 kb/s frame),
20 octets (5.3 kb/s frame), or 4 octets. These 4-octet frames are
called SID frames (Silence Insertion Descriptor) and are used to
specify comfort noise parameters.
          
G.726 is specified in ITU-T Recommendation G.726: 40, 32, 24,
16 kbit/s adaptive differential pulse code modulation (ADPCM).
It describes the algorithm recommended for conversion of a single
64 kbit/s A-law or U-law PCM channel encoded at 8000 samples/sec to
and from a 40, 32, 24, or 16 kbit/s channel. The conversion is
applied to the PCM stream using an Adaptive Differential Pulse Code
Modulation (ADPCM) transcoding technique.
          
G729 is specified in ITU-T Recommendation G.729, Coding of speech at
8 kbit/s using conjugate structure-algebraic code excited linear
prediction (CS-ACELP). For all data rates, the sampling frequency
(and RTP timestamp clock rate) is 8000 Hz. A voice activity detector
(VAD) and comfort noise generator (CNG) algorithm in Annex B of G.729
is RECOMMENDED for digital simultaneous voice and data applications
and can be used in conjunction with G.729 or G.729 Annex A. A G.729
or G.729 Annex A frame contains 10 octets, while the G.729 Annex B
comfort noise frame occupies 2 octets.
