An update is available to enable RTAudio narrowband ...

    The RTAudio narrowband exists between Lync 2010 clients and the Lync Server 2010 Mediation servers across a wide area network (WAN). Additionally, if the client detects a round-trip delay of more than 25ms, it automatically flips to a low-bandwidth codec (for example, Siren instead of G.722 for the conference audio).

    Hi, the RTaudio is dynamic so if Lync have enough bandwidth in a peer to peer call, lync will use normally RTAudio wideband. You can see the used codec in with the Monitoring Server on the Report for the user under media Quality Report, audio-stream, x-msrta is RTaudio and the sample-rate 16000 is 16khz for wideband.

    In head-to-head tests SILK has consistently outperformed the other Lync wideband audio codecs. Although the wideband version of SILK requires slightly more bandwidth than the wideband version of RTAudio it is much less than G.722 and also can perform better is less than ideal network conditions.

    Even though one of the tasks performed by an SBC is media transcoding, no SBC on the market today will transcode RTAudio. That must occur in the Mediation Sever. However, if Lync Media Bypass is enabled, all voice calls will be sent as G.711 which bypasses the Media Server. With Media Bypass, calls go straight to the SBC.

    RTAudio, as with a few other supported audio codecs, is provided in both narrowband (8 kHz) and wideband (16 kHz) options. The wideband codec is most commonly used in peer-to-peer Lync calls while the narrowband option can be used for either peer Lync calls or in some outbound calling scenarios.
