AMR-WB is codified as G.722.2, an ITU-T standard speech codec, formally known as Wideband coding of speech at around 16 kbit/s using Adaptive Multi-Rate Wideband (AMR-WB). G.722.2 AMR-WB is the same codec as the 3GPP AMR-WB.

TelcoBridges supports the G.722.2 variant. Unlike [[GSM-FR]], [[GSM-EFR]] or [[AMR]], no additional license is required when using G.722.2 in a TelcoBridges-based production environment.


TelcoBridges supports following options:


The following options are supported:
*'''packet duration''' options of 20, 40, 60, 80 ms  
 
*'''packet duration''' options of 20, 40, 60, 80 ms
*'''bit rates''' of 6.60, 8.85, 12.65, 14.25, 15.85, 18.25, 19.85, 23.05, 23.85 kbps

AMR-WB is codified as G.722.2, an ITU-T standard speech codec, formally known as Wideband coding of speech at around 16 kbit/s using Adaptive Multi-Rate Wideband (AMR-WB). G.722.2 AMR-WB is the same codec as the 3GPP AMR-WB.


TelcoBridges and G.722

TelcoBridges supports following options:

  • packet duration options of 20, 40, 60, 80 ms
  • bit rates of 6.60, 8.85, 12.65, 14.25, 15.85, 18.25, 19.85, 23.05, 23.85 kbps
