1. Bringing IP communications to the Microsoft desktop While the PC is a key communication tool, voice remains the strongest medium for user interaction, with devices such as desk phones and mobile phones carrying the most communication minutes. Increasingly, these three types of communication devices the PC, the desk phone and the mobile phone must all be able to access presence information and provide IM capabilities. Interactions are increasingly going beyond enterprise borders, and a new generation of IP communications must link employees with their colleagues within the organization as well as with their partners and customers. Because the workforce is composed of multiple generations of users, the desktop must reflect this heterogeneity, offering traditional and feature-rich telephony for some users and rich multimedia and media-session communications for new, hyper-connected users. A user profile-based approach is required because communication software must also be available from a wide variety of desk phones, mobile phones and PCs. Desktop integration of real-time communications offers tremendous benefits for enterprise users. The ability to interact with contacts more easily and quick access to project team members allow enterprises to realize cost savings, improve efficiencies, and increase access to knowledge leading to higher productivity with immediate and instantaneous communication, interaction, collaboration and knowledge-sharing. A key challenge in bringing IP communications to the desktop is for IT managers to leverage and integrate best-of-breed software while optimizing investments. In addition, business line managers are looking to improve office worker productivity; for example, with a solution that integrates Alcatel-Lucent telephony, collaboration and unified messaging capabilities with Microsoft Outlook e-mail. Alcatel-Lucent is a leader in the data networking, telephony, voice mail, audio conferencing and contact center markets. The company has decades of experience in serving small-to-large organizations with scalable and reliable carrier-class communications. Alcatel-Lucent has enriched its telephony platform with a full set of UC services, including IM, presence, video, unified messaging, web conferencing and application sharing. These UC services are all accessible from multiple devices, such as the PC, desk phones and mobile phones. The company s compliance with key standards in such domains as web services, IP security, and Session Initiation Protocol (SIP) simplifies the integration of best-of-breed software components. With deployment of Microsoft Office Communicator presence and IM, there is an opportunity to integrate Alcatel-Lucent OmniPCX Enterprise telephony as well as Alcatel-Lucent OmniTouch audio conferencing. By integrating converged desktops, IT managers are able to reduce the TCO and, leveraging existing directories allows implementation of a single sign-on for all applications and directory look-ups (see Table 1).

Connectivity topologies for Microsoft Office Communications Server 2007 There are two approaches to integrating the Microsoft Office Communicator environment with enterprise communication servers. The first approach is based on deployment of the Office Communications Server as a supplementary telecommunications server in the enterprise network. The second approach, which is recommended by Alcatel-Lucent, consists of the co-existence of the Office Communications Server with Alcatel-Lucent equipment, where the call control remains at the enterprise communication server level providing Office Communicator users with the benefits of both worlds. 2.1 SIP trunking With SIP trunking, the Microsoft Office Communications Server is seen as another node in the voice network, but with few features for the Office Communications Server population and without integration between the Office Communications Server and enterprise communication server populations. Office Communicator clients are able to call enterprise communication server extensions and access the Public Switched Telephone Network (PSTN) through the enterprise communication servers, but this topology creates silos of distinct users, with different levels of service for each population and limited interactions among populations. Implementing SIP trunking, the Office Communications Server requires a Mediant 1000 Gateway from AudioCodes. It interfaces Microsoft SIP with IETF SIP, supported by Alcatel-Lucent and all other telecom vendors. This gateway also endorses CODEC conversion between the Microsoft and the telecom worlds. This topology has multiple feature restrictions and creates tromboning of all voice paths through the Gateway, not to mention the bottleneck and single-point of failure that it represents. For all the aforementioned reasons, Alcatel-Lucent does not recommend SIP trunking implementations with Microsoft. Nevertheless, our expert team is ready to evaluate requests on a case-by-case basis. 2.2 Going beyond direct SIP interactions SIP trunking does not provide consistent usage for all enterprise users. But desktop integration of real-time communications, whatever the enterprise user and whatever the communications usage, offers a tremendous benefit for end users in their day-to-day jobs. 2 Enriching the Microsoft Office Suite with Alcatel-Lucent Unified Communications Solutions Application Note
2.2.1 Microsoft SIP trunking enhancements: dual forking To provide superior features compared to standard SIP trunking and a consistent, converged desktop experience for all enterprise users, Microsoft introduced dual forking: SIP trunking enhancements with twin-set functions in the Office Communications Server to associate the Office Communicator with the phone device. Alcatel-Lucent has never supported this integration because of potential complexities for end users and administrators due to dual call control, discrepancies between user experiences, and limitations in SIP networking. Microsoft has recognized the poor execution of such architecture and announced the phase-out of dual forking in July 2009. 2.2.2 Integrated voice call control and service virtualization To provide real-time communications and an easy, efficient Microsoft desktop experience for all users, Alcatel-Lucent recommends Microsoft Office Communicator integration based on voice call control integration and service virtualization. Users keep their phones on the enterprise communication servers and benefit from the Office Communicator interface on the desktop for all communication activities. This integration model provides the best of both worlds, offering a coherent communication layer along with a homogeneous, feature-rich end-user service level across the enterprise. Its many benefits include: Improved ROI on IT and telephony investments with enhanced functionalities Improved productivity for all users, whatever their profiles The Alcatel-Lucent voice call control integration solution is recommended for enterprises with one of the following requirements: Users who need a converged desktop with real, enterprise-grade telephony services: the main Alcatel-Lucent OmniPCX Enterprise business-class features are delivered to users Users in branch offices and a centralized telephony network to lower TCO: OmniPCX Enterprise handling of telephony services, supporting heterogeneous IP phones in the small branch office without requiring deployment of a local media server for voice flow optimization OmniPCX Enterprise ability to provide service continuity, whatever the size of the enterprise, from geographic redundancy in data centers to branch office survivability Control of local area network (LAN)/wide area network (WAN) bandwidth while offering enhanced voice quality Users with different profiles and communication usage/needs: OmniPCX Enterprise delivery of services to a variety of user devices PC multimedia, desk phones and wireless handsets so that users retain the benefits of their preferred devices while experiencing a converged desktop with the Office Communicator Mobile users with a broad range of devices: wireless LAN (WLAN), Digital Enhanced Cordless Telecommunications (DECT), cellphones, smartphones such as the RIM BlackBerry, Nokia Eseries, and the Apple iphone 1 mobile digital device and other phone brands that operate on Google Android or Windows Mobile platforms Users who need rich interactions with contact center agents, portals and attendants Users who need tight business process integration and a rich ecosystem, including voice loggers and notification servers 1 Apple and iphone are trademarks of Apple Inc., registered in the U.S. and other countries.

3. Maximizing the Office Communicator user experience with enterprise communications solutions For global coverage of customer needs, Alcatel-Lucent offers two options for integration with the Microsoft Office Communicator: 1. If a customer needs Microsoft presence and IM as well as enterprise telephony embedded in the Office Communicator client, and where multivendor enterprise communication servers are in place, Alcatel-Lucent recommends remote call control (RCC), supported using Genesys Enterprise Telephony Software (GETS). 2. If a customer needs Office Communicator as a converged desktop but expects to retain a high level of telephony services, Alcatel-Lucent recommends client integration with the Alcatel-Lucent OmniTouch 8600 My Instant Communicator (MIC). With this integration approach, users benefit from Unified Communications and Collaboration (UC&C) real-time features such as full business telephony, advanced audio conferencing, and unified messaging using the Office Communicator desktop. 3.1 Empowering Office Communicator users with telephony in a multivendor communication network GETS delivers telephony capabilities for the Office Communications Server. Microsoft users benefit from one-click access to their desk phone or Voice over IP (VoIP) softphone from Office Communicator, with the following features: Mid-call controls such as call transfer and call waiting Pop-up notification when the phone is alerted Viewing of the telephony presence of Office Communicator contacts GETS is a middleware solution, with telephony services under enterprise communication server control to offer enterprise-grade telephony services to all users whatever their phone devices: fixed/mobile, Time Division Multiplexing (TDM) or IP. GETS delivers a multivendor gateway that aggregates telephony and presence from the multivendor telephony infrastructure, including both IP and TDM (see Figure 1). The GETS solution simplifies the handling of software release evolution for both the Office Communications Server and multivendor IP enterprise communication servers. The GETS solution is targeted at companies who have chosen a multivendor approach for their enterprise communication server infrastructure and/or Microsoft only on the desktop for their employees. 4 Enriching the Microsoft Office Suite with Alcatel-Lucent Unified Communications Solutions Application Note

The OmniTouch 8600 My Instant Communicator is targeted at companies that have chosen to deliver enterprise-class telephony for high reliability as well as in-sourced, carrier-grade conferencing for fast ROI. Until now, to initiate communication a user had to select a specific device and channel for example, a telephone to call his or her contact. However, if the line was busy or there was no answer, the user could only leave a voice message and/or try another medium another land line or mobile number or try to communicate by sending an IM or e-mail (see Figure 2). Now, within an OmniTouch 8600 My Instant Communicator window, users can see the presence status of their contacts on each of the available media and can initiate communication using the preferred device and channel. With the media-blending capabilities of the OmniTouch 8600 My Instant Communicator, users can initiate an IM session with one click or answer a voice call with an IM (see Figure 3). Figure 2.

Audio conferencing integration will be available in H2 2010. 4. Federated IM and presence for borderless collaboration We have seen how Alcatel-Lucent UC solutions can enhance the Microsoft Office Communicator with real-time communications. We now consider collaboration interactions IM and presence in a multivendor environment. Even when a company has chosen a collaboration tool, its employees may need to communicate with contacts who connect using different IM and presence collaboration tools. These contacts can be internal, following company acquisitions or mergers, or external, such as partners, suppliers or vendors. The Alcatel-Lucent OmniTouch 8460 Advanced Communications Server (ACS) is the collaboration application server in the Alcatel-Lucent OmniTouch 8400 Instant Communications Suite. The OmniTouch 8460 ACS integrates an IM and presence federation gateway to enable exchanges between OmniTouch 8460 ACS users and other collaboration platform users, with support of Office Communicator 2007 IM and presence federation. Alcatel-Lucent IM and presence federation is targeted at companies that want to: Improve interactions among employees in a hybrid enterprise environment, saving on equipment replacement and user training Improve interactions with partners in a multivendor IM and presence environment, expediting communications, problem solving and collaboration while saving money and removing barriers to success 5. Active Directory and converged information repositories Alcatel-Lucent real-time communications solutions complement Microsoft communications applications and are also fully compatible with the desktop environment of enterprise users and compliant with IT policy. Companies are able to reduce their TCO by integrating converged desktops, implementing a single sign-on for all applications and directory look-ups on a unique reference directory, and leveraging existing directories. With the support of standards such as Lightweight Directory Access Protocol (LDAP)/LDAP over Secure Socket Layer (LDAPS) and assignment of a unique security ID to each user, the Microsoft Active Directory can be the universal repository for administrator and user information. During the bulk provisioning of users, the Active Directory can act as the reference database for user information, allowing administrators to gain operational efficiencies. The Active Directory also provides authentication of administrators and users who are accessing UC services with a single sign-on. 6.
