Microphone mute using wired headset during call?

[Don1713]

On my vzw Galaxy Nexus I could hit the inline button to mute/unmute the mic during a phone call. On my vzw Note 3 all it will do is hang up. I've tried holding it down longer, multiple clicks, even tried a few play store headphone control apps but nothing works. I'm on a lot of conference calls while driving and this has been the only issue I've had with phone. I'd rather not use bluetooth if at all possible.
