BB Pearl 8100 :: Voice Dialing Keeps Coming On / Phone Becomes Perma Muted

Pearl Flip 8230 on Bell Mobility v4.6.1.182 (Platform 3.3.0.64) Forgive me if I'm omitting any other needed information.Every so often the voice dialing app will come on by itself, prompting me to say a command. (On a side note, it never actually accepts any of my commands ever. But that's not my issue right now.)Even after I close it, a few seconds later it will pop up again on its own.I thought maybe it was a stuck side key, but I disabled it, assigning it to nothing.The phone becomes muted as a result of the above. I cannot hear the DTMF beeps when dialing, I cannot hear the ringing, I cannot hear the other person, and the other person cannot hear me.Needless to say this has made using my phone pretty much impossible.
