AT&T - U.S. IP Telephony & UC Services Report Date: July 13, 2012

Product Assessment: AT&T - U.S. IP Telephony & UC Services Report Date: July 13, 2012 Analyst: Whelan, Cindy Service: Hot Topics, Business Network and IT Services Market: Unified Communications & Collaboration, Business Network and IT Services - US Class: IP Telephony & Unified Communications Services (U.S.) Summary Current Perspective AT&T s IP telephony and unified communications services are threatening to competitors because the provider supports a suite of network-hosted, premise-based and managed services, backed by an extensive U.S. and international reach and a brand with global recognition. Most recently, the carrier launched its Unified Communications Solutions (UCS) offer, launched in January 2012 (please see AT&T Launches Cloud-Based Unified Communications Features, January 27, 2012), providing enterprise customers with a path to next generation unified communications and collaboration services. UCS consists of three elements: UC Voice is cloud-based IP telephony and unified messaging that was launched in the U.S. in late 2011; UC Central is a cloud-based client application that provides a single user interface for collaboration features that will be launched later in 2012; and Managed UC Solutions integrates vendor-specific solutions with AT&T VPN, SIP trunking, conferencing and security. AT&T backs its services with strong monitoring and reporting capabilities through its BusinessDirect portal, as well as professional services that include network and technology assessment, service architecture and design management, service development and deployment, operations and maintenance. AT&T sells its VoIP services to businesses of all sizes, but the carrier has a reputation for providing premium services that are most suitable for enterprise-class customers, giving competitors an opportunity to portray AT&T as an expensive solution for mid-size businesses. However, the AT&T brand is clearly a choice for companies ranging in size from large enterprises to mid-size businesses. Outside the 22 states where AT&T is the incumbent local carrier, other in-region incumbent operators will have an advantage targeting mid-market businesses and smaller customers. The table below details AT&T's IP telephony and UC product portfolios: IP Telephony Services Description AT&T Voice DNAManaged SIP-based network-hosted VoIP. AT&T IP Flexible ReachManaged IP trunking/integrated access offer that supports local, domestic long-distance and international calling. AT&T Business in a Box Managed turnkey voice and data service for small businesses or enterprises with branch offices in the U.S. Includes fully managed CPE, firewall protection and virtual private networking. Managed IP Telephony Fully managed, dedicated Cisco and Avaya based Unified Communications solution that can be located on the customer s premise or hosted in a data center. Unified Communications Solutions AT&T Unified Communications Integrated solution that combines real-time communication services such as chat, presence, IP telephony, audio/web Solutions conferencing and non real-time communication services such as e-mail. The solution is delivered across desktop, mobile and landline devices. AT&T Connect Enterprise-wide business application that includes integrated audio conferencing, web conferencing and video conferencing delivered from AT&T s global platform. AT&T Telepresence SolutionGlobal immersive and non-immersive videoconferencing offer available in 40 countries as a full-suite managed service, and in an additional 40 countries where customers own their own equipment. Strengths and Weaknesses Strengths AT&T offers an IP-enabled voice service for every segment of the market, from teleworkers to the largest multinational enterprises, and the carrier has offered VoIP solutions since 2001. AT&T is one of the best-known telecommunications brands in the world, and when it comes to selling to large domestic or multinational enterprises, AT&T has a name that gets it in the door. AT&T s UC solutions allow enterprise customers to phase UC features into their overall communications environment, preserving infrastructure investment where necessary and managing the process of transitioning and training employees on new features. Deployment options range from premisesbased solutions that can incorporate legacy equipment, to a hybrid mix of premises-based and network-hosted, to a fully hosted solution. AT&T UC Solutions support PCs and mobile devices, including smartphones and tablets that use the ios, Android, BlackBerry, and W indows Mobile operating systems. The bring Weaknesses As one of the world s largest service providers, AT&T has a reputation for designing and delivering premium services that target the world's largest corporations. Some competitors can take advantage of this by touting services that seem to have much lower prices up front, possibly hiding limited feature sets and extra charges until the customer is hooked. Other competitors specifically target smaller enterprise customers with relatively simple needs, using low-price VoIP services that offer fewer features, less options and limited quality monitoring and management which customers may consider sufficient for their needs. Several major carriers offer a shared trunking service option that lets multi-site enterprise customers share concurrent calling capacity among geographically distributed locations of an enterprise: locations are able to burst beyond the subscribed number of concurrent calls for their location by using idle concurrent calling capacity from their other offices. The feature potentially lets enterprises save money by managing the number of concurrent calling

your own device (BYOD) phenomenon is a big issue as employees rely on personal mobile devices for business tasks. W hen AT&T s UC Central launches later in 2012, it will include a mobile client that supports devices from vendors other than AT&T Mobility, although not all features may be supported across third-party wireless networks. AT&T eventually anticipates offering full support of all features across phones and tablets regardless of the underlying wireless provider. AT&T IP Toll-Free delivers inbound toll-free calls to U.S. locations. The service supports SIP-enabled features (i.e., SIP Refer, SIP Redirect), and interoperates across IP and PSTNbased contact centers. Interoperability with AT&T s Toll-Free Advanced Features and the ability to use AT&T Route-It! to control PSTN and IP network call routing allows customers to operate a hybrid environment. AT&T NetPROTECT call monitoring is available to AT&T IP Flexible Reach and Voice DNA retail customers, which reduces the risk of, and caps customer liability, in the event of toll fraud. packages, getting the maximum use from the packages purchased. AT&T has not launched a similar enterprise line pooling service. AT&T s Business VoIP Site Availability SLA could be stronger. The default SLA states that clients may be eligible for a one day credit if a problem from the AT&T network, dedicated access or CPE prevents customers from making calls for more than two hours. By comparison, CenturyLink customers may be eligible for a one day credit for affected units for outages of ten to 30 minutes; and Verizon offers a one day credit for affected units for every hour the service is unavailable. As the nation's largest carrier, many customers considering migration to VoIP will already be AT&T voice and data customers. AT&T will be selling customers on new technologies, but in many cases the carrier is moving its TDM customers to IP rather than adding new logos and new sources of revenue. Metrics AT&T s customer-facing W eb portal, BusinessDirect, streamlines customer self-service and provides detailed performance reporting for services. BusinessDirect gives AT&T Business VoIP customers an Administrator portal with access to reports, ebill, eorder, emaintenance and eservicing functions. The personal end-user portal lets individual VoIP users forward calls, view call logs, set up on-demand conference calling and listen to voicemail via any Internet connection. AT&T Consulting offers customers professional services options in many areas, including UC. W ithin its UC consulting practice, AT&T offers a series of service options that clients can mix and match to meet their needs, from establishing a UC roadmap to implementation and integration of Microsoft services.
