Comfort Noise with Lync Server 2010 Mediation Server

  • We are seeing a lot of the following Event Viewer warnings on our Lync Server 2010 Mediation Servers:

    The Mediation Server service has received a call that does not support comfort noise.  This event is throttled after 5 calls from a single Gateway peer.

    The Mediation Server service has received a call that does not support comfort noise from the Gateway peer, dmg2xxx.contoso.com

    Cause: The Gateway peer does not support comfort noise.

    Resolution:

    Please ensure the comfort noise option on the Gateway has been enabled.

    Where would this be configured on the DMG2xxx (Version 6.0 Service Update 7.0)?

  • DMG web interface --> VoIP --> Media --> Voice Activity Detection (ON by default)

    Hope this helps
