Users are requesting the ability to hang up a call without having to touch the device. Especially now that they are able to place calls hands-free. Before the "OK Vocera/Hey Vocera" hotword users were taught that whoever placed the call should end the call; the thought being that if the caller had a free hand to place the call they likely had a free hand to end the call. Now that users are placing calls hands-free that isn't always the case. I witnessed several users trying to say, "OK Vocera" hang up. Perhaps the hotword "OK Vocera/Hey Vocera" could be used to wake up the Genie during the call and then say "Hang up" or "End Call".
