5-Day Training - "Hands-on" Labs with 700+ page manual with Special SIP Essentials Section

Critical Course for Planning OCS Design & Certification Study for Exam 70-638, Exam 70-262 and other tests

OCS Forum (http://www.ocsforum.com) announced its new OCSR2-2010 Ultimate course. "R2 and Wave 14 coming in 2010 confirms Microsoft place in the new telecommunications networking business," noted Tom Cross OCS Forum CEO. "R2 is having a significant impact on corporate voice telecommunications strategies indicating the end of the TDM-time division multiplexed PBX-Private Branch eXchange systems is now insight. Microsoft is also driving companies like Cisco, Nortel, Avaya, NEC, Mitel, ShoreTel to rethink their featuresets and capabilities because while R2 is a new game when Wave 14 is released in 2010, their days are numbered," Cross commented.

This five -day (5-day) "hands-on" lab course with 700+ page manual focuses on the core components of OCS 2007 R2, including:

- Instant Messaging (IM) between everyone in the organization in the office or remote
- Application and Desktop sharing for true collaboration
- Audio/Video Conferencing including internally hosted audio conference calls and Live Meetings
- Integration with Exchange Server 2007 Unified Messaging
- Securing the environment to protect communications

The course provides many hands-on labs to practice and reinforce learning of many new concepts. After completing this course, students should be able to design, install, configure, maintain, monitor, and troubleshoot the core components of OCS 2007 R2.

11 Network Recommendations - All 52 recommendations can be found at http://www.ocsforum.com - signup for weekly newsletter.
- Separate SIP/VoIP applications by VLAN-Virtual LANs
- Implement MPLS VPN-Virtual Private Networks for both QoS and security.
- Evaluate and implement appropriate policies (protocol-level routing) based on types of user applications, e.g. IM, voice, SIP applications, etc.
- Add SAFW-SIP Aware Firewalls in addition to existing systems.
- Add IPSec for security, authentication, and encryption at the IP layer.
- Add Digital Certificates with Kerberos or third-party solutions.
- IDS-Intrusion Detections Systems must understand and be tested for SIP/VoIP protocols.
- Evaluate UDP encapsulated IPsec according to RFC 3948.
- Secure mechanisms should be used for traversal of firewalls. It has been reported by numerous sources that most NAT's do not work with SIP. SIP message contains IP address of the PBX and traditional NAT does not translate.
- Place feature and call processing servers behind firewalls (explained next).
- Add flexible security policies, e.g. add extended access lists to selectively encrypt or authenticate datagrams.

Authors - Actualizers - Auditors - Analyzers
First, Authors are the senior/executive management leaders providing strategic direction in the form of all-encompassing ideology.
Second, Actualizers was the best term we could find that covered anyone and everyone who touched data, applications, systems, managers, archivists and anyone else.
Third, Auditors may have the simplest role of checking on how actualizers followed authors' policies.
Fourth, the Analyzer reviews and checks the auditors to determine if the auditors are practicing their processes and documentation uniformly and universally across the enterprise. In addition, given increasingly compliance and regulatory oversight the Analyzers provide an additional independent layer of review and analysis. This additional layer of review is that the balancing security and privacy is getting more, not less complex.

Simple solution based on Microsoft unified communications software saves companies money versus traditional services

Gold Systems, a developer of voice-powered software applications for Global 1000 companies, has announced the launch of the Gold Systems Conference Server, a solution that allows companies to save money on conference calls compared to traditional conference services.
The Gold Systems Conference Server provides on-demand conference calling at a fraction of the cost of most outside conference services used by many companies. The Gold Systems offering uses Microsoft Office Communications Server 2007 R2, running on standard servers on a company's premises.
The system uses SIP trunks to deliver calls over an existing Internet connection, rather than traditional voice trunks based on physical wired connections, so they can be provisioned automatically only as needed. The system is quickly installed, requiring only power and a network connection. For conference participants the system is familiar: they are given a phone number, including a toll-free number if needed, and identification code to join a conference call.
Gold Systems has found that in today's challenging economy many companies are seeking ways to reduce their communications expense, and conference call services are one area receiving increased attention. At the same time, the economy has squeezed travel budgets, placing even more demand for conference calls.
"Until now it has not been practical for companies to host their own conference calls with any kind of scale," said Terry Gold, president and CEO of Gold Systems. "So conferencing service providers have thrived - and your costs have exploded. Gold Systems can help you quickly reverse this trend, giving you back control over this critical expense. You'll be able to immediately cut your conferencing costs and look like a hero because you reduced the budget while improving service to your organization."
For a heavy user of telephone conference services, Gold Systems Conference Server can pay for itself in just one to two months. Even light users will see a return on their investment in as little as five months according to the company. Gold Systems offers the flexibility of various pricing plans to meet a particular company's needs, including per-minute charges as low as 3 cents per minute. Full details can be found at http://www.goldsys.com/conference.
The Gold Systems Conference Server can also be a first step toward utilizing additional unified communications services based on Microsoft software. Other productivity and cost-saving capabilities such as presence, instant messaging and video conferencing can later be added with Microsoft Office Communications Server 2007 R2. "Gold Systems has long been a leader in using Microsoft unified communications technologies to deliver complete communications solutions to our customers," said Gold.
In addition to the Conference Server solution, Gold Systems provides software development and implementation services to help companies utilize the features of Microsoft unified communications products. Gold Systems integrates Microsoft Office Communications Server 2007 and Exchange Server 2007 with customers' telephony infrastructure, including PBXs, VoIP services, and mobile devices. This combination helps companies save money and improve productivity by providing on-site and mobile employees with integrated, easy-to-use conferencing, messaging and "anywhere" access. Gold Systems also offers a suite of voice-powered products, designed to enhance security and productivity, which work with the speech recognition technology built into the Office Communications Server platform.

About Gold Systems
Through its award-winning products and services, Gold Systems helps its customers identify where productivity can be improved with voice-driven solutions. The company's unified communications implementation services, as well as its self-service speech recognition solutions, allow businesses to improve productivity and profitability. Gold Systems is a Microsoft Gold Certified Partner and a 2009 finalist in Microsoft Worldwide Partner Conference Awards in Unified Communications Solutions, Voice. Since 1991, Gold Systems software has automated more than 1 billion telephone calls around the world.

Well-established SMB technology community portal SMB Nation is proud to announce its inaugural SMB VoIP workshop for channel partners, computer consultants, resellers and VARs. "Our intentions at SMB VoIP are two-fold," shared Harry Brelsford, CEO of SMB Nation. "First, we want to properly introduce our long-time SMB technology consultants to the amazing world of voice and specifically VoIP. Second, we want long-time telephony experts including interconnects and agents to embrace the SMB opportunity. This second group can benefit from our speeches on how to be a managed services provider. Our intent is to bring the SMB data and voice communities together and do good business."

The three-day workshop is "co-located" inside the well-established Channel Partners event (Virgo Publishing) at the Mandalay Bay Center in Las Vegas, March 1-3. SMB VoIP attendees will have full access to both shows and the exhibit hall (Channel Partners typically has 3,000+ attendees). The SMB VoIP workshop content offerings are both business and technical in nature. "We have content for all interests. For example, on the business-side, we have "How to Sell VoIP in SMB" and on the technical-side, we have a healthy debate about on-premises solutions versus hosted VoIP." Brelsford added.

Speakers include leading industry experts who will provide individual sessions and open panel discussions. "You will meet Erik Lagerway, Tom Cross, Jay Weiss, Karl Palachuk, Ray Horak, Doug Green, Chris Bangs, Daniel Williams, Matt Mackowicz and Matt Wass de Czege. We've brought in SMB-specific VoIP subject matter experts." Said Brelsford. "You can't afford NOT TO ATTEND to fast forward your journey into SMB VoIP right now!"

"If you don't "VoIP" your customers, some else will." Exclaimed Chris Bangs, director at Telephonation, a well-respected SMB VoIP portal. "Computer guys and gals must view this opportunity both optimistically and defensively. It's a new decade and a new economy and the VoIP opportunity on existing data networks is HUGE! Computer professionals need to learn IP-based telephone systems "yesterday" to protect their client-base. Not to mention telecoms are looking to take over network management from the computer consultant."

Click here for the Flash animated tutorial with the visual explanation of some of the different kinds of VoIP attacks. You need to be familiar with how they occur and what do to about them.

SIP/OCS Attacks

Like the weather, security and . . .other attacks
are now even more critical as disaster awaits us every day.
According to a senior consultant,
"it is always worse when the business is affected."

When you have obscene language injected into private calls or crossconnected calls allowing others to listen in on secret or confidential calls and do not have a SIP/OCS security plan in place, this is called a RGE-Resume Generating Event, ELE-Extinction Level Event and you're fired for cause or incompetence. If you are not fired, you will be on the list of "under performers" and laid-off, downsized or transferred to an undesirable location.

Understand your opponent has more time, is more focused and is more eager to attack you. While SIP brings advancement in VoIP call connections, SIP faces the same security attacks as other IP protocols such as HTTP-Hyper Text Transfer Protocol and SMTP-Simple Mail Transport Protocol such as:
- Malformed message attacks
- SPIT-SPam over Internet Telephony
- Memory "leak" buffer overflow attacks
- VOMIT-Voice Over Misconfigured Telephony
- DOS-Denial-of Service attacks (overload, part SYN, FIN)
- Eavesdropping
- Masquerading (Trojan Horses) as a phone, user, server, as a customer

- Calljacking - hijacking
- RTP/RTCP session teardown attacks
- RTP/RTCP malformed messages
- RTP/RTCP buffer overflow attaches
- RTP play-out or Media spamming
- SDP changing CODECs attacks
- Injection of malicious RTP packets into existing RTP flows and
other known and yet to be created attacks.

First of all this a great book on tele/presence. I like the / (slash) between tele and presence just like I preferred it in the term tele/conferencing. This is a multi-part book review and interview with one of the author(s) Tim Szigeti who is a member of the Enterprise Solutions Engineering Design Team at Cisco Systems.
To be brief, I will address three issues - technical, design, and human factors in each review and even if I did that for a year it would only cover a fraction of the very useful information in the book. You can read snippets that I will include in the TPF-Tele/Presence Forum newsletter or just go buy it from Amazon or Cisco Press Book Price: $49.50 and eBook Price: $15.40 - a great value at ten or even 100 times the price. How can I say that - because TP-Tele/Presence design is like the web ever-finished, final or friendly. That is, TP systems are very complex and the network design can be daunting, then there are the human factors which have, IMHO, held this concept back for more than thirty years.

Meanwhile not to waste any more of your time.

TECH-Tip - The authors recommend the implements of IEEE 802.1p/Q within TP networks. The IEEE specification defines a standards-based system for providing VLAN-Virtual Local Area Network tagging and COS-Class of Service (why the o is in lower case in CoS and in upper case in QOS is a mystery) across Ethernet networks. This is accomplished through an additional 4-byte tag (called a label in MPLS-Multi-Protocol Label Switching), which carries VLAN and frame prioritization information. The 802.1Q tag has a specific formation of four fixed-length fields. Two of the four fields carry the frame prioritization and VLAN information. If you want to see "visually" what this looks like click here or go to www.techtionary.com where you can the details in an animated tutorial. To conclude, the PCP-Priority Code Point bits provide eight levels of priority traffic priorities for Ethernet or Layer 2 frame level. For example, different classes of traffic are assigned to different CoS values such as VoIP/SIP/OCS might used CoS 5 value, tele/presence CoS 4 value and data traffic sent with a default of CoS 0 (zero). Bottom-line is if you are going to do voice, video or other multi-media communications you need to implement 802.1p/Q on the LAN. That is, QOS is important on the "last foot" as much as the "last mile."

DESIGN-Tip - It's the economy stupid, is common joke about what politicians should be really doing. In TP its audio, stupid. Why I say this is because we talk everyday often all day on cell phones where the audio skips and gaps occur all too often. In TP, it is really doubtful that that the video will ever be done correctly because it would simply take too much money to have sound stages used in network broadcast news along with makeup, news gathering and just good presentations skills. These issues are not forgotten and will be addressed in upcoming TPF Newsletter issues. However, the authors do an excellent job in room design and audio issues. They give specific valuable recommendations addressing the problems with audio. Paraphrased, the authors indicate, "Background noise and reverberation in the room can degrade acoustic qualities and even disrupt the audio switching behavior in multipoint (multi-location) meetings. Therefore, careful engineering of the environment must be done to ensure that ambient noise and reverberation levels with the room are kept in check. The goal is to re-create the experience of an in-person meeting. Cisco has defined precise targets and thresholds for ambient noise and reverberation . . . . providing a comprehensive test methodology for measuring levels and recommendations for remediating typical sources interference. The key point is to have a test and measurement methodology for all aspects of TP and a means for providing periodic auditing and improvement.

HUMAN-Tip - The book excels in many areas but it is the human factor that has kept TP or tele/conferencing from really being a part of mainstream business communications. Certainly businesses use it but there were video tele/conferencing systems thirty years ago (that's right 30) that were more advanced than what is commonly found available today. In the spirit of not wanting to wait another thirty years, here are a few human factors or as Mr. Hal Josephson, the keynote speaker of the TPF Expo calls it "tele-skills." In my book, Teleconferencing - Linking People Together Electronically focused on a wide range of human factors. For example, evaluation of the tele/presence experience should be an ongoing effort from the onset. Ultimate success depends upon a good starting point or base. When there is a basepoint or baseline is known, change, good or bad, can be measured. Here are a few examples of what to measure. Of course, you can come up with your own questions. How do people perceive and adjust to tele/conferencing? How is the speed, type and nature of inter-personal communication affected? How does tele/conferencing affect the duration and organization of the meeting? To keep this brief, please think of all the different communications patterns that existing in typical face-to-face meetings as shown by the very funny graphic shown in the newsletter available here.

http://www.telepresenceforum.org/newsletter/1-27/

Then consider how communication changes in a tele/presence meeting.
