Microsoft OCS-Office Communications Server SIP Essentials Course with Special Virtual OCS Lab - V.181
An Executive and Operational Guide to SIP & Microsoft OCS-Office Communications Server/Communicator - Available Classroom (onsite) 5 Days or online without lab.
This course was created to help enterprise technical-executive managers, channel partners and others better understand SIP-Session Initiation Protocol and Microsoft’s OCS-Office Communications Server. There is more than a year of research, interviews, discussions, meetings and presentations to channel partners, providers, manufacturer's and other interested parties in the SIP-VoIP industry.
In addition to the classroom presentation, a “virtual OCS” lab/demonstration will be included. The purpose of the virtual demonstration is to give attendees a “test drive” of OCS and be able to ask implementation and configuration questions. The lab is in the R&D stage of development and may change without notice. However, this list is being updated, please email for additions.
Course Overview and Outline
Who Should Attend: - This onsite and online course is designed for enterprise executive and technical managers, channel partners, VAR-Value-Added Resellers, SI-Systems Integrators, telephone interconnect, agents, master agents and consultants. In addition, this course will benefit corporate technical, staff marketing, training business development, sales, channel managers, operations, engineering, support and other corporate managers for SIP-VoIP providers, carriers and manufacturers.
What You Will Learn:
· Explore Microsoft’s OCS-Office Communications Server features, concepts, call flows, configurations and other issues for evaluation and implementation.
· Review the fundamentals of IP-Internet Protocol and platforms required for highperformance SIP-Session Initiation Protocol, IT-Internet Telephony or VoIP-Voice over Internet Protocol systems. This includes soft switches, gateways, routers, services and other critical components.
· Explore business applications and opportunities. Review what customers are buying today and why they are buying. In addition, emerging “killer applications” will be explained in depth.
· Quickly grasp complex subjects such as H.323, MGCP-Media Gateway Control Protocol and SIP. As SIP-Session Initiation Protocol emerges are the key VoIP communications protocol, discover how this technology will impact all voice communications systems from key, PBX-Private Branch eXchange, IP-Internet Protocol-PBX, hosted, managed and other systems.
· Understand basic and advanced SIP-VoIP concepts features. From hosted, managed, IAS-Integrated Access Service, and IP-PBX, quickly understands “what’s-what” for different customer applications and business models.
· Probe the issues behind Integrated and Converged Access. Understand when and why organizations need a converged access solution.
· Learn why “network assessment” is critical to any SIP-VoIP implementation and why this step cannot be overlooked.
· Address the issue of QoS-Quality of Service by overcoming jitter, echo, noise and other network problems. Review the role of RTCP-Realtime Transport Control Protocol and other tools to monitor and maintain high performance VoIP networks.
· Understand the functions of the new communications “toolbar.” See how the benefits of “unified communications” as they improve business operations.
· Assess the Top-10 issues why SIP trunking and hosted VoIP is more than “dial-tone,” and how it can represent change in the business and business model of even the smallest enterprises. Discuss and explore new ways to improve fundamental business processes.
· Explore how a SIP-VoIP call is processed and review potential security attacks. Discover how SPIT-Spam over Internet Telephony, VOMIT-Voice Over Misconfigured Internet Telephony, DOS-Denial Of Service and other terrorist attacks can target not just data, but voice packets.
