Nuerom causing a loud buzz when getting a second call?

[RavenII]

Damn it, I wonder what it could be, in the reg. I ran a program called "Advanced Configuration Tool" and I think that's what might have done it. Either that, or something else. I can't imagine it being the dialer only because it started doing it after having flashed the phone for a long while, it did it out of the blue. I'll try anything at this point, because it's gotten REALLY annoying lately.

OT: just noticed the signature, why did you go back to the Titan from the pro? just curious.
