To handle contacts via waiting lists you do like this:
The content of the merged Waiting list depends on which services and waiting lists you are logged in on. Which data you see is configured per media type, in CallGuide Admin, the Waiting lists in CallGuide Agent window. You may want to sort the contacts by e.g. Real-time media first or Shortest wait time first.
For callback appointments you see colours depending on your defined service levels. See Book Callback appointment in Edge Agent
