What Providers, Agents and Users are saying about these courses:  

According to Matt Jolly of Oxford Networks, “VoIP Business Executive course VoIP 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, 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 - Oxford Networks
............................................
“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

- 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.

-       SIP – exciting new applications

Online OCS-Office Communications Server

 Fundamentals of OCS  

Course Concept

The fee for this course is $499 per person with discounts for five or more and 50 or more (flat-rate) students.  That is, if you have need to train 10 or more students (staff, channel partners, etc.), the flat-rate option is extremely cost effective.  In addition, with a one-year contract the courseware can be installed on your servers for tracking, logging and other marketing purposes.

This course is not for the technical repair or programming of vendor-specific equipment.  It is a business strategy course that includes sales, marketing, technical issues and critical success issues needed to understand SIP and OCS technology. 

Like with life, there is not a consistent “look and feel” of the content.  Designing and animating requires an enormous amount of work and sometimes either font size or some other graphic factors are compromised to get the job done.  There are NO refunds.  However, we hope you like the enormous effort that went into building this innovative new approach to learning as this course is being constantly updated.  Your feedback during and after class is appreciated and will be incorporated into subsequent versions. 

If you need a "slice" of the course before you buy, here are two examples of 300+ other Flash-animated slides in this course.

In addition, you can also see more OCS tutorials on the following blog:

SIP & Microsoft OCS-Office Communications Server with Virtual Online Demonstration Virtual Lab

This is the online (e-learning) version of the executive and operational guide to SIP-Session Initiation Protocol & Microsoft OCS-Office Communications Server/Communicator. These are the exact slides presented in the classroom version but without the instructor.  The slides are pretty explanatory and interaction is available via email.  In addition, more than 30 multi-media audio (voiceover) tutorials are provided.  However, as we all know, online learning is like buying a book, you the reader have to push yourself through the book.  

This course is designed 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. 

As part of the online presentations, 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.   

This is not a "hand-on" lab but a online demonstration.  If "hands-on" labs are desired, please call for details on lab setting and additional costs.
