Any way to disable Entry/Exit tones in Conf Connection?

[paul.roche]

Is there any way to globally, or even better on a conference by conference basis, disable the participant entry and exit tones in Cisco Conference Connection 1.2(2)SR1 ?

Or can someone tell me the name and location of the specific Wav files for these two tones? I have not found them yet under C:\Program Files\wfavvid\Prompts\

Thanks.

Think I found out how to disable them globally here:

anyone know if there's anyway to make this a conference by conference parameter?
