What Providers, Agents and Users are saying about these courses:
According to Matt Jolly IT Consultant, “SIP Business Executive course training to a new higher level. For example, there is nothing like the tutorials SIP available anywhere or from anyone. For the channel partner or customer, this course provides critical insights for successful implementation and management. The new user interface speeds learning allowing viewers to grasp complex concepts faster than ever before. With this course, SIP/VoIP providers can rapidly accelerate the learning process for their channel partners which in turn accelerate revenues. Now is the time for users and providers alike to make this course an integral part of their business operations.”
Matt Jolly – Consultant
“I am writing regarding Tom Cross and the online training and VoIP/SIP course. By far this is the best program in place, as Tom is one of the most recognized trainers in the United States for VoIP/SIP. It might be worth to add this course to your sign-up package for agents around the country not only as a profit center but something that you could co-brand and have a “leg-up” on your competition.”
Bill Bowyer – CEO – VoIP in America
“The SIP/VoIP courses are more than a superb primer on VoIP/SIP technology; they are an indepth business plan for a VoIP/SIP implementation. In addition, the VoIP/SIP diagnostic and troubleshooting guide is the most thorough approach to VoIP QoS available. I need information that informs but does not overwhelm. Information that guides but not drives you away. The courses provide insights and actionable information that has helped me get the technology we need sooner but saved me a considerable amount in understanding what we didn’t need. The SIP course especially is a valuable one which provides much needed information in a readily understandable format.”
Paul Daubitz – President – ATI-TeleManagement
Who Should Attend: – This 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, software developers and hardware manufacturers.

This ebook is provided to all students of the SIP 2012 Business Applications Planning Guide Course and some concepts from the book are included in the courseware. However, since there is more than four years of vendor-neutral continuous research and development, the SIP 2012 Course provides a more comprehensive view of the subject.
SIP Trunking is one of the first complete books to planning, evaluating, and implementing high-value SIP trunking solutions. Most large enterprises have switched to IP telephony, and service provider backbone networks have largely converted to VoIP transport. But there’s a key missing link: most businesses still connect to their service providers via old-fashioned, inflexible TDM-Time Division Multiplexed trunks. Cisco® authors show how to use Session Initiation Protocol (SIP) trunking to eliminate legacy interconnects and gain the full benefits of end-to-end VoIP. Written for enterprise decision-makers, network architects, consultants, and service providers, this book demystifies SIP trunking technology and trends and brings unprecedented clarity to the transition from TDM to SIP interconnects. The authors “separate the true benefits of SIP trunking from the myths and help you systematically evaluate and compare service provider offerings. This book includes detailed cost analyses, including guidance on identifying realistic, achievable savings.” SIP Trunking also introduces essential techniques for optimizing network design and security, introduces proven best practices for implementation, and shows how to apply them through a start-to-finish case study. Some of the concepts explored in the book are
- Discover the advanced Unified Communications solutions that SIP trunking facilitates
- Systematically plan and prepare your network for SIP trunking
- Generate effective RFPs for SIP trunking
- Compare SIP deployment models and assess their tradeoffs
- Address key network design issues, including security, call admission control, and call flows
- Manage SIP/TDM interworking throughout the transition
- This IP communications book is part of the Cisco Press® Networking Technology Series. IP communications titles from Cisco Press – SIP Trunking book by Christina Hattingh, Darryl Sladden, ATM Zakaria Swapan was first published February 4 – 2010 available at www.informit.com – ISBN-10: 1-58705-946-0

NEW for 2012 – Designing and Planning Scalable SIP Networks
The five areas of discussion presented (with modifications I added) are:
Here are the highlights in text format:
1 – Benefits of Server Virtualization aka Abstraction
- Distributed user endpoints and application servers
- Scalable growth with QoS control abstraction
- MACS* via signaling “abstraction”
*Moves, Adds, Changes & SAS-Stand Alone Survivability – SAS enables backup for SIP devices by the multiple “abstract” local or cloud Media Gateway(s)
2 – Benefits of SIP Trunking
- Session and Signaling control layers for:
- On-net (IP PBX to IP PBX)
- Off-net (IP PBX to local PSTN)
- Off-net (IP PBX to LD/IDDD PSTN)
- SPOC/SMOC-Single/Multiple Point of Connection
- National control points for access (vendors) – Migration path to ALL-SIP & IMS-3GPP
3 – Benefits of Number Transparency
- End-to-end media control (transparency) for voice or other media types
- Access to SS7 applications for text messaging, mobility or call center routing
- Enterprise control over call completion whether PSTN or SIP rather than provider
- Migration path to E.164 & IMS-3GPP
4 – Benefits of SIP Routing
- Eliminates “mesh” network mess
- Add intelligent Session Layer 5 routing – Maintains end-to-end media transparency
- Add media CoS-Classes of Service – Adds SPOC NOC-Network Operations Center
- Migration path to ALL-SIP & IMS-3GPP
5 – Benefits of SIP Proxy Peering Networks
- Platform for multi-vendor services
- Ensures multiple CoS & QoS options
- Migration path to ALL-SIP & IMS-3GPP
- Foundation for any future network needs

- UDDI-Universal Description, Discovery and Integration uses standards-based services such as XML, HTTP, SOAP, TCP/IP (define above) uniform service description and service discovery protocol. Discovery services provide a consistent publishing interface and allow programmatic discovery (registration) of services. Description services provide the means for internet registration – to be found but not advertisement or placement on search engine listings. UDDI file structures are designed using a “publish-once-read-by-many” concept. That is, web site URL-Uniform Resource Locator can be designed using UDDI standard file structures which can be published to the UDDI server network. The UDDI network can be accessed (discovered) by search engines, customers and other list builders in a standard published (register) format. UDDI Registries and protocol servers with:
- White Pages – Names, Address, Contact and Vcard information
- Yellow Pages – Industry categorizations and taxonomies
- Green Pages – Technical information including internal URL file discovery structures
- UDDI is also designed to replace the robot.txt search engine web site document structure concept. Here are some of the web site description-discovery-registry information retrieved by search engine spiders/bots and other retrieval programs.
- Voice-driven yellow pages – SALT-Speech Applications Language Tags adds voice commands to web applications. SALT is an extended set of markup (meta) tags based on XML-eXtensible Markup Language though compatible with HTML-Hyper-Text Markup Language and others.
