2 Oracle s UC infrastructure solution combines tightly coupled session management, border control, and service management functions with comprehensive professional services that enable enterprises to deliver highly secure, reliable, and scalable UC services quickly and cost effectively. Enterprises are turning to unified communications (UC) solutions and all Internet Protocol (IP) networks to improve collaboration, increase worker productivity, and contain telecom costs. Next-generation UC platforms, interactive video solutions, smart mobile devices, and tablets are enabling a new virtual workplace, where one-on-one phone calls give way to rich multiparty collaboration experiences, and mobile information workers efficiently conduct business from any place, at any time. However, implementing an enterprisewide UC solution and extending real-time IP communications sessions including voice, video, presence, and instant messaging across IP networks can introduce a variety of deployment and operational challenges. Connectivity, security, and control issues can lead to project delays, budget overruns, and poor service quality. Oracle s UC infrastructure solution is designed to help enterprises overcome the unique connectivity, security, and control challenges encountered when integrating diverse UC solutions or extending UC services across applications and networks. The solution combines tightly coupled session management, border control, and service management functions with comprehensive professional services that enable enterprises to deliver highly secure, reliable, and scalable UC services quickly and cost effectively. 2

3 Unified Communications Deployment Challenges Enterprises face the complex connectivity, security, and control challenges deploying or integrating UC systems. Connectivity Information technology teams often run into difficulty when connecting disparate communications systems, business applications, and fixed and mobile endpoints. Protocol interoperability issues can complicate the integration of multivendor IP private branch exchanges (IP PBXs) or UC servers, or the interfacing with SIP trunking services. And third-party endpoint devices may not be able to access the full range of UC services. In addition, IP PBXs, UC servers, and SIP trunking services and endpoints may support different codecs and varying methods for conveying Dual Tone Multi-Frequency (DTMF) tones, fax tones, and SIP response codes. Network administrators may have difficulties integrating autonomous IP PBX and UC systems because of overlapping addressing schemes or dissimilar dial plans. Security Protecting real-time workforce and customer interactions from attacks and intrusions is important for any business. SIP trunks and internet-facing services open the enterprise to a wide range of threats and service quality concerns, including denial of service (DoS) attacks, viruses, and IP telephony spam. Attackers can leverage public domain scanners and reconnaissance tools to identify and exploit security weaknesses from inside or outside the enterprise. Attackers may try to manipulate signaling or media flows, disrupt network infrastructure, eavesdrop on confidential exchanges, or commit service theft. Conventional IP security devices firewalls, intrusion detection and prevention systems, and antimalware solutions are not designed to control real-time IP communications sessions and thus do not address the unique security or service quality concerns associated with real-time communications (RTC). Limited Control Managing distributed heterogeneous UC environments including administering dial plans and routing across diverse IP PBXs and UC servers can be a labor-intensive, error-prone proposition. Identifying, isolating, and resolving signaling and call quality issues can be challenging, especially across vendors and service boundaries. Enterprises need cohesive session management solutions to intelligently route traffic across trunks, interfaces, and resources to optimize cost, availability, and service quality. And enterprises need unified management, monitoring, and analytics solutions to efficiently troubleshoot problems and ensure high service levels in real time. 3
