asterisk users - Aug 2005 - help with waning on OSS/dsp, condition 16 and 17

Hi,

I hope someone could help me, or at least give me a hint about this error.

ERROR =>

Aug 18 10:48:51 WARNING[17120]: chan_oss.c:838 oss_indicate: Don't
know how to display condition 16 on OSS/dsp
    -- Started music on hold, class 'default', on OSS/dsp
    -- Stopped music on hold on OSS/dsp

    -- Started music on hold, class 'default', on OSS/dsp
    -- Stopped music on hold on OSS/dsp

This always happens when: Im making a call with x-lite and i put on
hold to make a second call. What can I do to make * know how to
display the condition. Anyways i can put on hold the first call and
make a second call, but it bugs me that message. Maybe i am not
defining quite alright the music on hold or something like that, I
would apreciate someone to point me out a direction to take.

Thanks,
Claudio Canseco
