Explanation

The Hybrid Message Service enables integration between Cisco IM and Presence (IM&P) clusters and the Cisco Webex Cloud Messaging service, providing unified and consistent messaging across on-premises and cloud environments. For encrypted communication between the on-premises IM&P clusters and Webex, the following configurations are required: 1. Hybrid Message Service License: The Hybrid Message Service requires a specific license installed on the Cisco Expressway-C, which acts as the hybrid connector between the IM&P clusters and the Webex cloud. 2. Webex Certificate Management: To ensure encrypted communication, Webex must manage certificates automatically. This simplifies deployment and ensures proper handling of secure TLS connections between on- premises and cloud services. 3. Multiple IM&P Cluster Support: The Hybrid Message Service supports multiple IM&P clusters, making it suitable for global enterprises with distributed deployments.
