Voice Codecs. Codecs generally provide a compression capability to save network bandwidth. The WiFi connection
utility supports the following International Telecommunications Union (ITU) codec standards:
Codec Algorithm
ITU G.711 PCM (Pulse Code Modulation)
ITU G.722 SBADPCM (Sub-Band Adaptive Differential Pulse Code Modulation)
ITU G.723 Multi-rate Coder
ITU G.726 ADPCM (Adaptive Differential Pulse Code Modulation)
ITU G.727 Variable-Rate ADPCM
ITU G.728 LD-CELP (Low-Delay Code Excited Linear Prediction)
ITU G.729 CS-ACELP (Conjugate Structure Algebraic-Code Excited Linear Prediction)
An administrator can export VoIP settings to configure various codec data rates and frame rates to improve voice
quality in VoIP transmissions. To create a VoIP profile:
NOTE: Check that Voice over IP
is not disabled in the Administrator Tool Application Settings. It is enabled by
default.
1. Click Include Profiles in this package.
2. Click VoIP.
3. Click Add to open the Create VoIP Profiles page.
4. Select the Codec bandwidth, application usage, and frame rate. For Voice Data:
G711 has 10ms frame rate with 64kbps bit rate
G722 has 10ms frame rate with 64kbps bit rate
G723 has 30ms frame rate with either 5.3kbps or 6.4kbps bit rate
G726-32 has 10ms frame rate with 32kbps bit rate
G728 has 2.5ms frame rate with 16kbps bit rate
G729 has 10ms frame rate with 10kbps bit rate
Select parameters from the drop down menus.
