I called a company after hours using Google Voice, and the call waited for me to leave a message. But I just wanted to hang up. There was no hang up option on the screen, and I could find none by visiting the four Google Voice tabs. I finally restarted the device, and that seems to have hung up. That company will receive a voice message containing a very long silence.
