Running Windows 7 Professional SP-1 32-bit, I need a way to have reliable notification when a new message arrives via Google Hangouts g-chat. The notification needs to be visual, not auditory, because my desktop audio is muted during the time when notification is required. If I am working on my desktop with another window in focus, the g-chat thread does not come to the foreground when there is a new message, which results in an unacceptable delay before I become aware of the message. There is a Hangouts desktop App, but it doesn't work on 32-bit Windows.
An alternative to desktop notification would be an auditory notification on my iPhone. I have tried installing the Hangouts App on my iPhone, but it does not deliver notifications, even though it is configured to do so. My cellular service provider has done troubleshooting, and believes there is an issue with the Hangouts App, itself, because my iPhone delivers notifications for new text messages and new Emails, and the only notifications which are missing are from Hangouts. If there is a third party application which would produce a desktop notification when there is a new g-chat message, or an auditory iPhone notification, that would be helpful.
