Sound that I can get rid of *SOLVED*

[vMAC]

Ok so I've had a custom ROM for about the last three months and about every month I have to change it because of the same problem.
The problem is that I get this annoying sound that beeps right when I hit the button to initiate a call. It starts when I'm roaming, but then even after I get back into a service area it continues. The only solution is put another ROM on the phone. Here's the thing though, it doesn't beep like that when I have all the sounds on the phone turned off, or when I have the phone on vibrate. Only when I have the sound on does it ring. Anyone know how to get rid of this?
