    I use VOIP discount program to make calls on the home stationary phone and while it works perfectly well from BootCamp, I'm experiencing unbearable screeching noise as soon as I try to use my USB headset in Parallels/VMWare to make a call.

    It's really frustrating as I thought that by installing the latter I wouldn't have to boot into BootCamp anymore solely for the purpose of using VOIP.

    Could anything be done about it at all?

    Please let me know.

    In parallels and VMFusion they virtualize the USB bus, thus you will get MUCH less bandwidth then a non-virtualized machine. My experiences has been that you can't get more then 4 or 5 mbps across the interface. I send data via 2 115kbps links and even THAT has delays and other issues. My guess is that this is what your problem is, the sounds is just getting dropped, or cutup because of this. The headset is expecting data periodically, if it isn't being filled it just plays the random data in the buffer which sounds like screeching.

    Not much you can do about it.

    I read some discussions that it's an Apple's problem and they are aware of it; supposedly they will be fixing it with 10.6.3 - I really hope they do.
