A general definition of Unified Communications that seems to have been broadly adopted across the board is: Unified Communications is when multiple communications tools come together in a way that brings much more value to the end user than any of the communication tools stand alone.
The definition of Unified Communications and Collaboration is the integration of multiple communication & collaboration tools with presence, behind a single user interface, accessible from wired and wireless devices, and is designed to deliver real business benefits to customers.
UC gives you a single control point to access multiple applications utilized independently today - with the device you want to access it through.
Unified Communications offers businesses the ability to significantly improve how individuals, groups and companies interact and perform.
Collaboration has become mission-critical for enterprises seeking to create agile, effective organizations.  Imagine connecting employees, partners and vendors in a manner that suits them wherever they are, over any device - wired or wireless, PDA or personal computer.

The Unified Communications (UC) market has been rapidly evolving. AT&T is seeing three megatrends in this space.
1. The first megatrend centers around mobility. It has three elements.
The first element is an explosion of mobile devices as either primary or secondary computing / communications platforms. While traditional Windows-based desktop and laptop sales are flat, mobile devices such as smart phones, tablets, and netbooks are experiencing rapid growth. The AT&T UC strategy has as one of its core design points the delivery of a full, innovative UC experience across a wide range of mobile devices and platforms.
The second element of the mobility megatrend is the effort to utilize “multiple persona” technologies to eliminate the need for individuals to carry multiple devices. This trend is being driven by the convergence of three interests: businesses are excited at the prospect of securely utilizing an employee’s existing mobile device rather than provide a company-purchased one; employees would rather carry one device than two; and carriers would prefer not to subsidize multiple devices. Our company’s status as a provider of both mobile and network services with strong presence in both the consumer and business markets offers AT&T unique opportunities to enable this trend. Our UC strategy will drive multiple persona capabilities. In the process, it will leverage the opportunity to harness the consumerization of IT inherent in this trend.
The third element focuses on mobility as a platform for business applications. Organizations want to utilize UC to streamline business processes and exploit the growth in mobile devices to accelerate this. The AT&T UC strategy of opening our underlying UC platform to customers and 3rd party developers to tap into presence, chat, conferencing and other UC services supports the growth of mobile CEBP (Communication Enabled Business Processes).
2. The second megatrend is a move towards providing UC from the cloud. While this is part of the larger trend toward cloud-based computing, it has special significance for Unified Communications. AT&T customers are looking for two flavors of cloud-based UC. Many larger enterprises are looking to leverage their existing substantial investments in premises-based voice, video, and user management infrastructures and acquire the remaining UC elements from the cloud via a “hybrid” solution. Smaller companies, along with larger companies looking to migrate onto new infrastructures or integrate new acquisitions, are more interested in taking the entire UC solution from the cloud. The organization’s size, technology strategy, and existing premises-based investments will determine the mix between a hybrid UC deployment and a full cloud-based implementation. The AT&T UC Services strategy will support both designs.
 3. The third megatrend is the need to enable UC to work effectively beyond an organization’s firewall. People have a need to find the presence of, chat with, and collaborate with people outside of their firewall in a simpler, more scalable way than corporate IT can support today. As part of our UC strategy, AT&T is planning to implement federation on a broad intercompany scale to address this market need.

4. Mobile Applications Are liberating the employee and continue to grow in demand

PC focused, office user
Movement toward non-windows based devices
Individual applications with different functionality
Mobile-centric devices, integrated with wireline networks:
Integrated wireline/wireless solutions, least cost routing
Single Number Reach
Fixed Mobile Convergence
Communication enabled business applications
Companies are experiencing changes in the behaviors of their employees as new generations of workers are joining the workforce. Employees are becoming more technology savvy and are eager to share their ideas, experiences and work in “on-line” communities and require flexible working arrangements. Mobile devices, and the ability to deliver applications on a users device of choice, virtually in the world they choose is key to attracting and maintaining the best talent.
Historically, business employees have been in the office, working from a PC and a desk telephone. Increasingly, individuals have a mobile phone that is used regularly for work-related calls. These are even more attractive as they are enhanced in several ways. Fixed-Mobile Convergence gives your mobile phone the same telephony functionality as a desk phone. The FMC application allows a mobile phone to be transparently integrated with a PBX and to be used as an alternative to the desk phone. Additionally, single-number applications allow a single number to ring multiple devices,
including a desk phone, a mobile phone, a home phone or a temporary phone.
Voice over IP/Wi-Fi will let your mobile PC, dual-mode mobile phone or other device act like a desk phone that can make and receive calls.

Unified Communications brings major benefits in productivity, and responsiveness to customers, decision making and business interactions throughout the supply chain. The ability to instantly connect people, information, and teams can do more than maximize productivity—it can transform the way organizations conduct business.
Historically, the requirements and cost of supporting multiple unified communications tools delivered in the form of on premises hardware and software (multiple licenses, expensive upgrade and support costs, and integration challenges) has discouraged organizations from taking advantage of the full benefits of UC.
Moving UC to the cloud makes it possible to solve the challenges of coordination and management. Cloud-based solutions, with their ability to bridge the gaps between offices, companies and geographical locations, can reduce the cost and complexity of UC. Applications delivered as a service through the Cloud enables an organization to scale and gain the flexibility to meet dynamic business requirements. The AT&T global network underpins these cloud-based technologies, delivering services at the scale and service levels needed by organizations operating in global and dynamic environments.
Cloud’s real contribution to business agility goes further—speeding up time to market, lowering barriers to innovation, accelerating business transformation, minimizing risk in new business ventures and helping to deal with fluctuating market conditions. As a result, cloud promises to support top-line growth by increasing an organization’s ability to quickly respond to business opportunities and challenges while controlling costs through more efficient use of assets.

Cloud components can be integrated with existing on- premises and hosted capabilities, benefits include:
Preserve existing investments
Expand capacity
Enhance functionality
Provide single point of responsibility for integration
Growing adoption of UC, collaboration and federation among enterprises is creating new challenges for businesses. Organizations are needing to implement the components of UC to satisfy communications needs of employees across many functional areas. Whether cloud or premises based, the result is either a rip and replace solution or multiple solutions with limited integration.
Many future UC installations will take the form of a hybrid as a service architecture. This calls for some functionality to be delivered from the cloud with other functionality delivered via premises-based platforms. For example, an enterprise may rely on the cloud for some functionality (for example, presence, video and Web conferencing) while maintaining on-site platforms for voic and until they are fully depreciated.
Cloud-Based, Hybrid UC solution architecture enables customers to leverage existing communications investments, integrating new UC components helping transform business processes, as well as inter- and intra-enterprise communications.
