A Second Generationof Unified CommunicationsIs Beginning


UC Decision Makers show growing preference for As-a-Service

As-a-service (third-party, shared)

We use a provider to deliver it with its shared infrastructure, which we pay for in a pay-as-you-go model

Base: 547 North American and European Enterprise and UC Decision Makers who work at firms that are piloting, implementing, or expanding UC Source: Forrsights Networks And Telecommunications Survey, Q1 2011, NOTE: Percentages may not total 100 percent due to rounding

Managed services (on-premise)

We use a provider to manage it, but we own it, and it’s operated at our site

Hosted (third-party, dedicated)

We use a provider to manage it; we own or lease any equipment, and it’s operated in a dedicated environment at the provider’s site

OutsourcedWe use an outsourced provider that manages the entire capability

Self-maintainedWe manage it ourselves (including software licenses, servers, etc.)
