October 30, 2007 4:49 PM | 0 Comments

Boulder: Boulder Valley School District’s Lifelong Learning Program proudly announces innovative online courses designed for high school students and adult learners. As technology continues to evolve at break-neck speed, it has become increasingly critical for students of all ages to stay ahead of these advances. The new Lifelong Learning “Internet Studies” Program online courses are the perfect Web-based solution.

According to Shere Holleman, BVSD/LLL, “Our classes reach over 4500 students each year and most of them take place in school district facilities. However, in today’s ‘split-second society’ there is an urgent need to provide flexible learning options where students can attend classes anytime, 7 days a week, 24 hours a day from anywhere. In addition, Internet Studies can help keep students on the cutting edge of technology so they can compete in the global economy.”

Students and adults alike are faced with an increasingly competitive work environment. BVSD’s Lifelong Learning Internet Studies program helps address this problem by allowing anyone to get answers to many technical questions through online learning and this partnership with TECHtionary.com.
Tom Cross, TECHtionary.com and Internet Studies developer/instructor, explains, “New technology continues to expand more rapidly than ever, as WiFi, WiMax, SIP, Voice over IP, Metro Ethernet, storage, web conferencing and other emerging technologies become more widely accepted. To offer a truly innovative education, students of all ages need to know all about today's technology and be informed on what's being developed for tomorrow. With Internet Studies online courses, anyone can become a credible expert.”
Online courses are available for $155 each.   Course titles include:
-          Internet Studies 101:  Communications Technology Manager – Introduction to the Fundamentals,
-          Internet Studies 201:  Wireless Technology Manager – Job Training and Implementation of WiFi, WiMax, Cellular and IMS

OCS-Office Communications Server Exposed – SIP Mediation Server

October 25, 2007 7:19 AM | 0 Comments
What sounds more like having an “intervention” or “meditation,” Microsoft refers to their “media” server as a mediation server. The Mediation Server communicates with the IP-Internet Protocol to PSTN-Public Switched Telephone Network TDM-Time Division Multiplexed gateway and the Director to provide connections from the PSTN network into the OCS-Office Communications Server 2007. In addition, the Mediation Server provides:
• Translating SIP over TCP (on the gateway side) to SIP over MTLS-Mutual Transport Layer Service (on the Enterprise Voice side)
• Encrypting and decrypting SRTP (Secure Real-time Transport Protocol) on the OCS side
• Translating media (conversations) streams between OCS and the media gateway
• Connecting clients that are outside the network to internal ICE (Interactive Connectivity Establishment) (explained later in this presentation) components to enable media traversal of NAT and firewalls
• Provide as an intermediary for call flows that a gateway does not support, such as calls from remote workers on an Enterprise Voice client (referred to as PBX devices).
 
Shown here is one of the many cool applications coming with SIP applications:
On demand business meetings, training, broadcast announcements, call-to-meeting notifications, even reverse 911 are enhanced with SIP trunking. "Event" notification can also be enhanced with SIP Trunking for fire-public safety or business applications such as sporting-concert events, restaurant-airline seat availability or stock price monitors.
 
If you want to know more about OCS, this and more than 100 other concepts are explained in a new course called SIP Essentials – OCS Special Edition available online or in a classroom. There is also a separate version for channel partners wanting to explore offering OCS to their customers. For more go to: http://www.techtionary.com/nacse/istudies-ocs.htm

OCS-Office Communications Server Exposed - New Ideas "Inside"

October 22, 2007 9:19 AM | 0 Comments
Starting today I will look "inside" Microsoft's OCS-Office Communications Server. Certainly its one of the most fascinating approaches to VoIP/SIP and one worth considering by anyone looking into UC-unified communications or simply wanting a better way to communicate. I will explain some of the new terms and concepts in OCS starting with GRUU. The Mediation Server uses GRUU-Globally Routable UA-user agent URI-Uniform Resource Indicator to identify the gateways that are associated with the Mediation Server. Some SIP applications require a UA-User Agent to construct and distribute a URI which can be used by router on the Internet to route a call to that specific UA instance. In other words, a URI which routes to a specific UA instance is called a GRUU.

SIP-VoIP Alert: Microsoft OCS-Office Communications Server "Shock & Awesome"

October 16, 2007 8:20 AM | 0 Comments
Maybe not since 1-1-1984 with the breakup of the Bell System has there been such a time to re-think the telecommunications business.  Today, Microsoft officially enters the CPE-Customer Premise Equipment or hardware side of the telephony business.  Rumors abound that Microsoft will also, in response or anticipation of yet another threat from Google, get into the network side becoming a carrier or provider.  Given the cash on hand they could easily buy almost anything they want.
 
Meanwhile, I am at the Broadsoft Connections Conference (www.broadsoft.com) where VoIP and SIP is "Scaling New Heights" with lots of new products with video phones, call center tools, cool converged hardware products and exciting product products (www.sutus.com) and CRM integration with SalesForce.com (www.salesforce.com) and many others which I will write more about.
 
In response to Microsoft’s entry, there is not panic but great uncertainty when people were asked. For many its, more “shock and awe” than “shock and awesome.” For me, it’s the greatest time in a long time as new energy and ideas will emerge with new and cool SIP applications. In addition, efforts by the SIP Forum www.sipforum.org and its many members like Chris Gatch the CTO of Cbeyond will certainly accelerate “the need for speed.”
 
Meanwhile, back to the Conference, I leave you with some more details on Microsoft OCS-Office Communications Server. Office Communications Server 2007 supports three types of MG-Media Gateways. These MG's include basic, collated and advanced.  A basic media gateway requires the support of a Mediation Server to route a PSTN call to the Unified Messaging client. The basic media gateway requires the support of the Mediation Server to route the calls from the Unified Messaging clients to the PSTN.
 
A collocated media gateway resides (collocates) with a basic media gateway and the Mediation Server on a computer that is using the Microsoft Windows Server 2003 operating system. The collocated media gateway may reduce provisioning, installation and management costs when compared to the other types of gateways.
 
An advanced media gateway has the features of the basic media gateway and the Mediation Server. An advanced media gateway does not require a separate Mediation Server to handle the signal and to translate media that is necessary to route a PSTN call to the Unified Messaging client.

OCS-Office Communications Server - SIP-VoIP Learns New Tricks

October 4, 2007 10:41 AM | 0 Comments
With October 16, the release date of OCS fast approach, the world is buzzing all over.  The telephony world is going to get a "new sheriff" and better get ready to learn telephony according to Microsoft.  Starting now, I will add some of the cool new features and explain the way Microsoft approaches the telephony (SIP/VoIP) world.  Concepts like Forests, Schema, Kerberos, Active Directory and the vast array of other Microsoft terms will be explored.
 
Today, we begin with Federation. OCS-Office Communications Server supports both 1-1 and 1-X messaging internally and Federation IM-Instant Messaging. With one-to-one instant messaging, two users can exchange IM-instant messages. With I-X-group instant messaging, three or more users can exchange instant messages. Federation IM is IM allows communications of IM, exchange notification and presence (SIP) with users of another organization.
 
This presentation is part of the SIP-VoIP Essentials online course available from TCMnet at http://www.tmcnet.com/tmcnet/mkt/nacse/sip-essentials.htm or the version for Channel Partners called NVBE http://www.tmcnet.com/tmcnet/mkt/nacse/.

Book Review of "Securing VoIP-SIP Networks"

October 2, 2007 1:01 PM | 0 Comments
“Once in a blue moon you read a book that not just meets but beats your expectations.
The book I am referring to is Securing VoIP Networks by Peter Thermos and Ari Takanen, Addison-Wesley,
ISBN-0-321-43734-9, www.awprofessional.com.
The more you read, the more you want to read. All too often technical books are too-deep or too-high.
This book provides practical, understandable and most importantly, implementable (new word) information.
As a SIP course developer and trainer, I am always looking for something to help students learn and do more.
This book does that and more. Guess by now you know how I feel, so I will stop.”
