Last week the Agent Communications Panel for Microsoft Dynamics CRM 4.0 has been released and is now available from the Microsoft Download Center. It allows a certain amount of customization such as integration with the Response Group Service of Office Communications Server 2007 R2. That said, it uses the Agent WebService of RGS to determine the agent group memberships. And given the title, it of course also integrates with Dynamics CRM 4.0.
