When deciding on the setup of Avaya Contact Recorder (ACR) you need to choose between G.729 and G.711 as codes. What are two implications of recording calls using G.711 rather G.729? (Choose two.)
A.
Several times more bandwidth will be needed between the recorder and the source.
B.
Bulk recording capacity of a given server will be about halved.
C.
The quality will be a little lower for bulk recording, but a little better for Quality Monitoring (QM).
D.
The storage space requirements for Quality Monitoring (QM) will be different from bulk recording.

Voice Recording
The Avaya Contact Recorder supports two types of audio codec: G.711 (64kbps) and
G.729 (8kbps). The choice of format depends on your switch type and network
topology.
G.711
If the recorder receives audio in G.711, recordings will be compressed by the recorder
and stored as G.729 (8kbps) files (unless compression is deliberately disabled by
setting acr.disablecompress=true in the properties file.)
The implications of receiving G.711 (and compressing it) rather than receiving G.729 in
the first place are:
Several times more bandwidth will be needed between the recorder and the source of
the audio
Bulk recording capacity of a given server will be reduced by about 30% if the server
does not support SSSE3.
