VAD suddenly stopped working on my Pearl today...I had used it earlier in the day, and then an hour or two later it wouldn't work.

It's like the phone can't hear me...I initiate VAD and hear the "Say a command" prompt. I say "call john smith" (someone in my phone book) and nothing happens...VAD then says "Say a command" again (and will interrupt me if I don't say my first command quickly enough) and ignores me again when I say "Call john smith" a second time. Then VAD closes.

Anyone have any ideas...I've done a battery pull, no joy. Never had any problems before, no new apps loaded and no changes to my Pearl in a while.

My speaker phone works fine, I tested calling someone on it and they could hear me fine.

I'm mystified!

Any help greatly appreciated!
