B179-CS1KR75

Another combination that could be used in low bandwidth environments would be to give high

preference to the compressed G.729A codec, with fallback to G.711, as shown below. In the case

of G.729A, ensure that the VAD setting matches that configured in the CS 1000. In this case,

checking Enable VAD results in G.729AB. After choosing an appropriate codec preference list,

click Save. Note also that for this release of the Avaya B179, G.711 is required to be in the

codec list with G.729 in order for call hold by CS 1000 telephones to operate correctly.
