  • background noise 10.1

    ever since we upgraded to 10.1 users have complained about background noise when using the speakerphone on 230 phones. (we have hundreds of this model)

    it only happens with the speakerphone, using the handset, don't hear any background noise.

    on 212's and 560's, doesn't sound as bad, but sounds sorta hollow

    our codecs are set to:

    Intersite list
    G729/8000
    PCMU/8000
    PCMA/8000

    Intrasite List
    PCMU/8000
    G729/8000
    PCMA/8000

    have tried this is the custom file, sevcustom.txt

    # Please consult Shoreline support before editing or deleting this file
    Layer2Audio 5
    SpeakerLevels 8192,258,410,649,1029,1631,2584,4096,6492,10289,14 333,517,0,0

    (the above is on the same line, it wrapped when I pasted)

    and tried this one too...

    # Please consult Shoreline support before editing or deleting this file
    Layer2Audio 5
    SpeakerLevels 4096,258,410,649,1029,1631,2584,4096,6492,10289,16 306,0,0

    anyone have better luck trying to get the background noise out.
