audio algorithm
The system will automatically select the best audio algorithm based on the call rate and the capabilities of the remote system. Use this menu to disable audio algorithms in case you want to remove “low quality” audio, or if you have interoperability issues calling other systems.
G.711
Normal quality audio (telephone quality 3.1kHz at 64kbps). This audio algorithm is manda- tory for video conferencing equipment and is impossible to uncheck.
G.728
Compressed normal quality audio (telephone quality, 3.1 kHz at 16kbps)
G.722
High quality audio (7 kHz at 48kbps, 56kbps or 64kbps)
AACLD
G.722.1
Compressed high quality audio (7 kHz at 24kbps, 32kbps and 48kbps).
