You can use the 
icons to give us feedback or to share a page via email. We automatically insert information about the page from which the email was launched and our feedback address (infodev@avaya.com).
However, you can replace the address with any you like if you want to share a page link with anyone else.
The icons may appear within specific pages. There are also two permanent icons at the top-right of the site:
• Use Default Email Application
Share feedback using the default email application on your PC or device.
•
Use GMail
Share feedback using a Google GMail account if you have one.
