Audio Alg (con’t) When Siren7 (16, 24 or 32 bit) is available, select
the audio algorithm in the following order: Siren 7
(16), G.728, G.722, G.711, Siren7 16 bit and G.728
algorithms are interchangeable, and a participant
using either one will be fully connected when one
of them is selected as the audio algorithm.
If the conference line rate is higher than 128 Kbps,
to achieve the best audio and video quality, select
the audio algorithm in the following order: G.722.1
(32), G.722.1 (24), G.722 / G711.
In Transcoding or Continuous Presence
conferences, you can set the audio algorithm to
any of the available audio algorithms as in a Video
Switching conference.
In Transcoding or Continuous Presence
conferences, you can set the audio algorithm to
any of the available audio algorithms as in a Video
Switching conference. If set to "Auto", the system
will try to connect the participants using the best
possible audio algorithm selecting it in the order
described for Video Switching conferences.
In Audio Only conferences, the default algorithm is
G.711 (56).
In a VOIP (Audio Only, IP Only) conference, you
can choose between the default G.711 (56) and
the G.729/G.723.1 (8) audio algorithm.
VTX1000 The VTX 1000 is a high quality, Wide Band PSTN
conference phone that can be used with the
Polycom MCU. During endpoint capabilities
exchanges a modem is used and the G.722.2
algorithm implemented. the VTX 1000 users are
allocated resources during the conference.
Select the checkbox when using VTX1000
endpoints.
Note: The system.cfg flag, VTX1000=YES and the
Entry Queue must be enabled in the MGC
Manager.
