Introduction
Unified Communications (UC) has exploded in recent years, and with good reason It isn’t a revolutionary idea to centralize the various components of real-time communication However, the technology has evolved to a point where the implementation has very much caught
up with the vision, making everything from inbound call routing to IM manageable under a single umbrella, with a consistent interface and cross-platform compatibility Traditional PBX (Private Branch eXchange) systems connected to standard the Public Switched Telephone Network (PSTN, or POTS – the Plain Old Telephone System) are quickly being abandoned in favor or flexible, scalable, cost-effective Internet-based solutions, saving businesses money, providing powerful new features, and bringing control of communications systems back to the businesses they support
However, as all of the parenthetical notes in the previous paragraph suggest, Unified Communications can be an overwhelming bowl of alphabet soup, especially to businesses just looking to connect their employees to each other and to their customers This beginner’s guide to unified communications will help decode the jargon and give organizations a jumping off point for evaluating solutions to meet a wide range of communications needs, whether connecting call centers in the Philippines with engineers in Canada or connecting coworkers across an office
The Components of a UC Solution
Unified Communications solutions can vary widely by vendor and can easily be customized
to suit a particular organization’s needs That said, most UC solutions include a number of key components (Gartner broadly identifies six areas that are universally included in all major vendor offerings):
• Telephony and Voice: This was essentially the origin of UC How can businesses take the new VoIP (Voice over IP) technologies replacing traditional phone systems, improve upon them, and integrate them with other forms if Internet-based communication? Many vendors offer specific phone hardware as well as back-end appliances (or cloud-based services) to support voice communication over IP networks instead of the PSTN
However, telephony can also be more loosely implemented on everything from iPads to user-supplied mobile phones to desktop computers and usually includes organizational directory and contact functions As UC matures, voice communications increasingly overlap with the other functions below
• Conferencing: While video conferencing used to be either an expensive proposition exclusively for enterprises that could afford specialized video capture, display, and transmission hardware, the conferencing within modern unified communications can

include any voice or video solutions that enable real-time collaboration among multiple users Document sharing, desktop sharing, remote presentations, group video chat, and conference room video all fall under the conferencing label
While telephony functions tend to have a fair degree of feature parity across vendors, conferencing tools fall on a much wider spectrum Some still require specialized hardware and additional appliances while others are strictly web-based and can use the webcams found on nearly every laptop sold today From the conference room to the hotel room, conferencing is quickly becoming a UC killer app for improving collaboration
• Messaging: In UC nomenclature, messaging is usually differentiated from IM (Instant Messaging, described below) Messaging, also often referred to as Unified Messaging or
UM, generally refers to voicemail, fax transmissions, SMS (text messaging), and, in some cases, email Few UC vendors include email as native components of their messaging suites but most include hooks to external email services Although email remains a critical, high-volume piece of the business communications landscape, most businesses have already invested significant time, money, and effort in existing email solutions long before they consider UC, so this approach actually offers significant flexibility
• IM and real-time presence: The key differentiator between messaging and IM is the asynchronous nature of messaging Emails and faxes, for example, can be sent and viewed
as users have the opportunity IM, on the other hand, generally involves near-real time interactions between users sending quick notes and messages back and forth
While IM is nothing new, with services like AOL Instant Messenger, Yahoo Messenger, and Google Hangouts making the technology completely mainstream among both consumers and enterprise users, the real-time presence aspect of IM has emerged as a critical feature for many businesses Finding out where an officemate is and whether she is available to meet can be challenging; when colleagues are spread across time zones and continents, branch offices and home offices, electronic means of tracking availability become indispensible In UC solutions, the ability to determine a coworker’s physical or virtual (and often, mobile or remote) presence is usually integrated with instant messaging features
• Client/user experience software: The actual user experience in UC is determined by client software While the client software may actually be presented in a web browser, most
UC vendors include both mobile and desktop “fat clients” These are resident applications that manage all aspects of messaging, telephony, and presence for the user, as well
as providing single sign-on to integrated applications Clients may include full-featured softphones (software for making voice and video calls on mobile and desktop devices), contact databases, chat features, and more, depending on the vendor
• Integrated applications: Vendors may provide APIs, pre-built integrations, or even their
Trang 4ziffdavis com 4 of 4
own integrated software and services to extend the capabilities of UC solutions Integrations can be as simple as basic federation or may involve deep business process automation for CRM, call center management, business intelligence, email, and beyond This extensibility is both a minimum requirement for a UC solution to be called “Unified Communications” and the area in which UC can demonstrate its real power When UC can begin transforming and simplifying workflows and breaking down silos among groups, colleagues, and partners, it moves from being a glorified phone system to a mission-critical business tool
No Matter How You Do It, It’s Time to Unify Your Comms
The business and technology research firm, Gartner, recently released its 2013 report on the state of the Unified Communications industry For the first time, they identified UC as a
“mature” market, entering the “mainstream adoption phase ” With VoIP and telephony forming
a core of UC and conferencing/collaboration tools emerging as highly effective, money-saving replacements for both traditional phone service and business travel, UC solutions are taking advantage of ubiquitous broadband and powerful technologies that impact both productivity and an organization’s bottom line
By including IM and real-time presence functionality, integration with a variety of business systems, messaging services, and even fax capabilities, UC ensures that employees can always be connected to each other, to customers, and to partners, regardless of their location
or the device on which they work In fact, UC is helping organizations make the most of BYOD, telework, and remote/virtual office facilities, with new device- and location-independent clients and the ability to connect employees to communication services anytime, anywhere
Most importantly, the barriers to entry for businesses looking to move to a UC architecture are now incredibly low Hosted systems keep companies from making large capital expenditures in hardware, software, and in-house support for UC, while robust and highly scalable on-premise systems can take advantage of advanced virtualization and deep datacenter investments where they are available The notion of “UC for everyone” is no longer a fantasy for SMBs looking for a better way to communicate and collaborate while large enterprises have more options than ever to dramatically enhance their external and internal communications
