This document provides an overview of Microsoft Dynamics 365 Customer Service (Dyn365CS) integration with bots and voice capabilities. It discusses direct routing, using telephony with Dyn365CS for omnichannel experiences, and configuring the Azure Communication Services (ACS) for direct routing. Potential issues that could occur are outlined such as calls without sound or wait music continuing after a call is transferred. The document recommends tools to stay organized when setting up these voice integrations such as using Excel for tracking, working with a telephony partner, filing support tickets, and leveraging diagnostic tools like SIP tracing and ACS logs.
