December 2007 Archives

The following are examples of Simple & Enterprise Deployments based on Microsoft documentation. It is highly unlikely that these configurations will “fit all sizes” and after considerable research, please see read this as guidelines, not absolute configurations. Here are the major configurations:
 
1 - Simple Deployment Path - Internal Access Only
Standard Edition Server
Scale - one server (up to 2,000 users)
Features
     - IM/Presence/Conferencing including A/V, Web, IM conferencing)
     - Integrated address book server (ABS)
 
2 - Simple Deployment Path with External Access
Standard Edition Server
Scale - two servers (up to 2,000 users)
Features
     - IM/Presence/Conferencing including A/V, Web, IM conferencing)
     - Integrated address book server (ABS)
 
3 - Simple Deployment Path with CWA & Archiving
Standard Edition Server (CWA-Communicator Web Access)
Scale - five servers (one mediation server) (up to 2,000 users)
Features
     - IM/Presence/Conferencing including A/V, Web, IM conferencing)
     - PSTN-Public Switched Telephone Network access
 
4 - Enterprise Scale Collocated Topology
Enterprise Edition Server with Load Balancer
Scale - 5,000 users per servers
Features
      - Mission-critical Large Enterprise IM and Conferencing usage
 
5 - Enterprise Scale - High Scale, High Availability
Enterprise Edition Server with Load Balancer
Scale - 11+ Servers (5 roles) 50,000+ users per pool (goal)
Features
      - Mission-critical Large Enterprise IM and Conferencing usage
      - Optional SQL clustering
      - Multiple IIS-Internet Information Servers for security
 
Here are some explanations of various servers:
- Access Edge Server - remote access, public IM connectivity (PIC), conferencing signaling
 
- Web conference Edge Server - external access to conferencing, remote/federated/anonymous user
 
- A/V-Audio-Video Conf Edge Server - conferences with external users, point-to-point A/V calls, voice to external UC endpoint
 
- Reverse Proxy - access to web services including ABS-Address Book Server
 
- Front End (FE) Server:
- The front end server role of OCS (or the Director) is responsible for processing and routing the call to the UM-Unified Messaging server.
- Cannot be on the same Active Directory server as the OCS server
- Can be used for SSO-Single Sign on for SIP traffic, UM, etc
- Allows for “seamless” functioning such as missed call notification, naming and priority and so forth.
- Perimeter Server (PS):
- Server or servers dedicated to authentication, security policies, etc
- ISA- Internet Security and Acceleration server is an example
- Usually multi-homed, i.e. having more than one NIC-Network Interface Card installed for outside to inside traffic direction.

Virtual OCS Labs is an advanced technical and operational guide to Microsoft OCS-Office Communications Server/Communicator also available as a companion to the classroom (onsite) formats of three-five (3-5) days, online or custom version courses. These courses are designed to help enterprise technical-executive managers, channel partners and others better understand installation, configuration, management and troubleshooting of 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 OCS and SIP-VoIP industry. 
 
Virtual OCS Labs takes our OCS training to the next level,” noted Tom Cross TECHtionary CEO. “OCS is a complex product taking a truly distributed approach to voice communications. Rather than a single box approach, OCS consists of a large number of separate servers providing specific voice, mail, meeting, database, domain, directory and other functions. This makes planning and understanding all these elements even more critical, Virtual OCS Labs provide key truly indepth “hands-on” insights for success,” Cross added.

OCS will extend “presence” throughout Microsoft Office® and other applications, reducing "info lag" (office jet lag) finding the right person, dialing the right number and using the right communication (audio, video, animation, group) in the right context (1-1, 1-X, X-1, X-X) at the right time (real-time, shifted, archived). Estimates vary, however, approximately 45 minutes a day can be saved by the business user whose vmail, email and faxes can be routed to a single inbox. The benefits only increase with the number of missed calls, misdialed outbound calls, wrong numbers, out-of-office message exchanges, etc. Dial-by-name instead of number has been reported to save telephone-intensive staff 15+ minutes a day alone. In the future, with technology metrics, the speed of communications will be measured in OV-Organizational Velocity, the speed of communications throughout an organization.
 
Even though there are considerable security and compliance risks associated with IM-Instant Messaging the majority survey respondents still use consumer-grade IM applications. However, SPIM-SPam over IM and other vulnerabilities is protected through via OCS. OCS also offers an increasing series of developer tools and API-Applications Programming Interfaces to provide enhanced SIP presence controls. Voice will treated like data elements like data in a database with multi-media presence components accelerating voice-enabled business processes. 
 
One-day class offered at the Leading IP Communications Event in Miami
Norwalk, CT, [December 11, 2007] — Technology Marketing Corporation (TMC), announced today that their TMC University division will offer a Microsoft Office Communications Server (OCS) training course at INTERNET TELEPHONY Conference & EXPO East 2008 in Miami, Florida. The daylong course, which includes a 30-minute certification exam, will be held Wednesday, January 23rd, day one of the three-day conference.
Titled, ‘Introduction to Microsoft OCS’, this TMC University course offers an initial training session teaching users how to integrate Microsoft’s new platform into their existing infrastructure.
According to TMC President and conference chairman, Rich Tehrani, TMC University is the only independent program of its kind. And this new OCS certification course is an overdue addition to the series.
“Since Bill Gates’ unveiling of Microsoft OCS in October, enterprises have scrambled to determine the most effective way to integrate its considerable advantages into their organizations. This new course gives the necessary background for enterprise telecom and IT managers to make smart recommendations about what’s best for their companies,” said TMC president Rich Tehrani.
The program will be taught by Thomas Cross – CEO TECHtionary.com, an innovative communications advisor with considerable expertise in market planning and development, hardware/software design and development, project management, intellectual property in telecommunications, information technology, conferencing, teletraining, telecommuting, groupware, networks, call centers, internet, artificial intelligence and other fields.
Cross commented, ”OCS is the most profound innovation in telephony since digital PBX systems.”  “It is very likely OCS will be a ‘must-have’ for business communications.  By adding this training course  to the Miami program, attendees can attend a one-day class that prepares them to make recommendations to their companies about an OCS strategy.,” Cross added. 
The TMC University Microsoft OCS Course consists of sessions covering the following topics:
Introduction and Overview
OCS business communications scenarios:
·         Instant messaging
·         On-premise Web conferencing
·         On-premise audio/video conferencing

Here is my lead-in:

OCS Insights – News/Views – Tips/Tricks on Microsoft’s Office Communications Server
This newsletter will focus on all aspects of OCS, LCS-Live Communications Server, Exchange Server, Active Director, Media Gateways, Mediation Server and all other systems and technologies related to Microsoft’s entry into the internet telephony business.
 
Microsoft’s entry into internet telephony is profound in many ways.
First, consolidation of acquisition may be the most significant. In survey after survey, the number #1 business issue that companies, large and small want from a supplier is “one-stop” shopping for acquiring and maintaining services. Today, the internet telephony business portends to provide more than VoIP services but alas most SIP/VoIP providers offer internet telephony but little else. Interconnect companies, many too old or scared to learn IP and VoIP, pooh-pooh VoIP/SIP alarming their customers by saying “you don’t want to put all your eggs in one basket, do you?” Lastly, the vast array of software providers, VARs and other channel partners offer a piece to the puzzle but often no or integration of voice. No more. OCS is the future. OCS will consolidate acquisition for customers giving them fewer vendors and ideally improve performance at a lower cost. OCS is also good, if not great, for the internet telephony industry. OCS will “lift all boats,” at least those that can learn to “tack” to the new wind blowing. 
 
Second, integration of voice as “just another application” is long over due. We don’t need to have separate networks for voice and data. That is a myth that is driven by the dinosaur providers who are trying to save in vain their legacy investments. We also don’t need to have devices separate devices for integrated applications. That is, we don’t need desksets (for most users). Deskset telephones are like desktop PCs, yes some occupations still require a desktop. However, if you have a laptop the idea of a desktop telephone is like requiring the user to carry a boat anchor. In addition, with users extending their usage to the home, hotel, etc. there is little want to carry something else along. Lastly, there are a lot of really great headsets that give the user not just one but two earfuls of audio which is something that even A. Bell didn’t give us.
 
Third, OCS gives us something new. New is a good thing. OCS will make voice really exciting like what is going on in mobile telephony. Look at what the iPhone has done it has given a major wakeup call to the cellphone industry. I have an iPhone and stood in line to get it. I still tell people that the iPhone is a one of the most significant innovations in technology because it truly integrates a vast array of services in one device. OCS will bring about new opportunities and new ways we haven’t thought of before including embedded and multi-dimensional content. Oh, I wrote a book on artificial intelligence so I can attest to the fact that there are many innovations that need a new platform to become market reality. In simple terms, think of OCS making voice as simply programmable software.
  
These are just three reasons why we are doing this new newsletter – consolidation, channels and content.
 
From now on, we at TMCnet at committed to bringing you news on OCS implementations, challenges, new approaches, innovations and more.
If you have suggestions for indepth pieces, please send them along.
 
Cheers and great stories ahead,
Thomas B. Cross – Columnist
