Introduction

Multi-cluster UC support is a critical requirement for many large customers and is needed to support a variety of use cases. Primary Use Cases may include supporting larger user capacities, enabling geo-clustering for multi-national clients and supporting corporate segregation requirements. However, multi-cluster implementations present several deployment and configuration challenges. These include handling increased feature complexity, achieving consistent provisioning standards, facilitating a standard dial plan scheme for centralized management, catering for platform inheritance and systems integration, and providing seamless user integrations.

This document serves as an overview of VOSS-4-UC’s current support for multi-cluster customer deployments. It offers several best practice recommendations pertaining to Global Directory Search, User Integrations, Day 2 User and Feature Provisioning, Dial Plan Management and Overbuild, leveraging current field implementations and internal test efforts. Furthermore, known caveated scenarios are clearly defined with mitigating options suggested as far as possible.
