• The Dedicated Instance add-on bundles Cisco Unified Communications Manager, optional Cisco Unified IM and Presence, Cisco Unity Connection, Cisco Expressway, Cisco Emergency Responder in the Americas region only, and optionally Cisco Session Management Edition. fact in context
• Dedicated Instance is a single-tenant cloud calling option built on the Cisco Unified Communications Manager architecture and integrated with Webex Calling for centralised administration. fact in context
• Calling features are not harmonised between Dedicated Instance and Webex Calling multi-tenant; for example a multi-tenant Webex Calling user cannot be a member of a hunt group hosted on Dedicated Instance. fact in context
• Cisco positions Dedicated Instance as a low-disruption migration path from on-premises Unified CM, preserving the same features, user experience and integration options and requiring no retraining for existing Unified CM customers. fact in context
• A fully deployed Dedicated Instance cluster supports up to 8 call processing servers or approximately 50000 devices on Unified CM version 14 and above. fact in context
• On the evidence gathered, the choice between Dedicated Instance and Webex Calling multi-tenant turns on whether the organisation wants to preserve its existing Unified CM feature set and administration model or is willing to re-platform onto Webex Calling's native feature set; Cisco does not publish an explicit decision tree or a named migration tool that distinguishes the 2 paths. inference in context
