Cisco’s Unified Communication as a Services, for hosted & managed
IP Telephony, offers a proven end-to-end integrated reference architecture for Unified Communications and IP telephony services, specifically targeting large, Enterprise and Service Provider deployments.

The VOSS Unified Services Manager (USM) product from VisionOSS has been fully integrated into the Cisco’s UCaaS architecture.

The business objectives of the UCaaS deployment platform proposition for Managed IP Telephony are as follows:

• To provide service providers with a pre-integrated, pre-tested managed IP telephony platform, based on the Cisco NSITE tested UCaaS architecture
• To provide a cost effective solution both for initial business trials and production deployments
• To provide a resilient platform architecture capable of scaling beyond 100,000 IP devices without any significant re-design and with investment protection

The UCaaS solution architecture supports a rich range of customer features (including virtualised: IP-PBX, extension mobility, voicemail, attendant console, presence, mobility, XML interface and much more), and this in turn presents a range of packaging and customer operations options. A number of product offerings for the VOSS-USM solution are available to support different customer segments, which can be helpful in terms of differential pricing and aiding network and dial-plan optimization.  It can also support different customer operations models that handle different customer types.

Some of the factors that differentiate UCaaS from its competitors include:

• The rich feature set of Call Manager and PGW Softswitches
• The Cisco end-to-end, integrated architecture
• Centralised management, without the need for centralised call control
• Multi-tenant capability, with customisation for each tenant
• Cisco's Unified Communications application roadmap

The architecture is highly scalable and can be deployed in a number of different line-ups:

• Standalone
• Managed
• Hosted, Managed
• Hosted, Multi-Tenant
• Hybrid
