The Cisco UCaaS solution provides a number of benefits to Service Providers and large Enterprises (Government Agencies):

• Enables Service Providers to customize full-featured IP-PBX telephony services for multiple tenants, departments, divisions and locations, including secure, devolved management for each tenant.
• Accelerates Unified Communications deployments and new services launches
• Minimizes disruption to users when migrating from existing telephony environment to new managed Unified Communications solutions
• Simplifies telephony management through Web-based automated provisioning, deployment, and management, providing centralized management without the need for centralized call control
• Reduces operating costs through business process automation and customer self administration of day-to-day moves, adds, changes and deletes, using an extensive set of secure, web-based administration, self-care or bulk operational tools
• Supports overlapping dial plans, enabling agencies or enterprises to support different dialing and telephony environments, invisibly to existing users. Ideal for migrations to new IP telephony environments, allowing groups of users to begin benefiting quickly from advanced IP telephony capabilities without disrupting service for existing users of private branch exchange (PBX) or analog services.
• Supports regulatory features, such as lawful intercept, 911, and other capabilities.
• Allows multiple departments or agencies to administer and customize their  valued-added services available.
• Supports highly dynamic environments, enabling agencies, large enterprises, and service providers to acquire or divest agencies or subsidiaries and grow to more than 200,000 phones while managing them as a single entity, simplifying integration with other business and operating support systems and reducing operational complexity and costs.
• Automates and simplifies large-scale site roll-outs, providing real-time, phone-based provisioning to save time and reduce associated deployment logistics and costs.
• Enables mass configuration through the ability to integrate bulk load capability in support of migration programs and to allow much faster rollout of IP devices and services.
