Audio Clarity
Audio Clarity improves received audio from participants connected via low audio
bandwidth connections, by stretching the fidelity of the narrowband telephone
connection to improve call clarity.
The enhancement is applied to the following low bandwidth (4kHz) audio algorithms:
• G.729a
• G.711
Guidelines
• Audio Clarity is supported with MPM+ and MPMx cards only.
• Audio Clarity is enabled by the SET_AUDIO_CLARITY System Flag in system.cfg
using the Setup >System Configuration menu.
Possible Values: ON / OFF
Default: OFF
