Does anyone know if there is a way to have chat notifications (audio) mute automatically when an agent is on a call? 

What is happening is that the agents are picking up calls and talking to the customer when a chat request comes in and the audio is so loud, we have to tell the customer to hold on until we dismiss the chat request. A lot of the time, we are away from the help desk looking up the persons issue, so it can be pretty distracting and jarring. I know we can log out of the chat when we take a phone call, but that requires the agent to remember to log back in when done with a call. 

If there is a way to have chat audio mute when on a phone call, that would be awesome.
