I didn't change anything. Mid-call suddenly no one can hear me anymore. It's done that a few times before but rebooting or toggling modem off and on fixed it, but not anymore. 
I've tried maxing all the volume under Audio, I've tried pressing all the different options mid-call, I've tried updating, nothing. At best I can be heard for a few seconds. The other lines say they can hear when I push buttons (speakerphone, tones, linejack, etc) but nothing from me.
