There is a Lifesize icon in the notification area of a Windows client that displays a red ball when you have missed a call. If you hover over it it displays the number of calls you have missed. You can also see missed calls in "Recents" and they show up in red. If you clear "Recents", it does not clear the icon in the Windows notifications area. The only way I have found to clear the icon is to exit the application and restart it. Is there a better way to clear it?
