Preferred Codec |
G711u or G711a |
This parameter specifies the primary codec that the Voice Gateway (VG4xx ATA) should use for audio compression and transmission during calls. The preferred codec is chosen based on its balance of audio quality and bandwidth usage (for example, G.711, G.729). If the preferred codec is unavailable, the device may fall back to secondary codecs if configured.
The Preferred Codec is based on per region. So the default system Tag value reflects what region they are in as its a Per Region Tag. For example, USA location preferred codecs are :
For UK or Europe location Preferred codecs are :
|
|
Second Preferred Codec |
G711u or G711a |
This parameter specifies the second-choice codec that the Voice Gateway (VG4xx ATA) should use for audio compression and transmission during calls. If the primary (preferred) codec is unavailable, it is used as a fallback option. This ensures continued call functionality with an alternative codec that maintains a balance between audio quality and bandwidth efficiency. |
|
Third Preferred Codec |
G729a |
This parameter specifies the third-choice codec that the Voice Gateway (VG4xx ATA) should use for audio compression and transmission during calls. It acts as a fallback option if both the primary (Preferred_Codec_1_) and secondary (Second_Preferred_Codec_1_) codecs are unavailable. This ensures robust codec selection to maintain communication in diverse network conditions. |
