Tanjay (LG-Nortel) “Cannot download certificate because domain is not accessible. If the problem persists, contact your system administrator”

Posted by Mino on February 20, 2009

I had this problem with the Tanjay new phone when I plugged it to my DHCP network and i was not able to find the problem .

However after little trials i found the below solution.

 Normally there is two ways to logon to Active Directory:

1.       Domain\username

2.        username@domain.local


I was getting this certificate error because I was trying username@domain.local  however I have found that if you log into the phone using domain.local\username


The phone is able to find the domain and download the certificate.


I found this out while doing a packet trace on the phone one day and found this search behavior


Netbios AD name: test

UPN Suffix: test.local

DNS Suffix: abc.com – this is given to the phone via DHCP

 So the DNS queries from the phone was this


Away from all these complicated trace like stuff, if you want to solve this problem just login with domain.local\username   and it will work fine  J

Posted by Mino on February 4, 2009

Below are some snapshots from our LAB to represent how the response group service will look like from the agent side.

I have configured a group with memebers , also i have configured a call workflow to ask whether for English language or arabic language .

In the below snapshot , both fady and Rami are two help desk agents who are logged in . when the call comes both parties recieve the call.


















when Rami answers the call , it gives him information about the call flow that the client used in order to get connected to him . on the other hand Fady recieves a confirmation that Rami has answered the call .

New services in front end server of OCS 2007 R2

Posted by Mino on February 4, 2009

I will be posting in details about those features which we have tested in the LAB here, including details about the CRM integration. The below are just a summary for the new stuff.

Office Communications Server 2007 R2 front end server also includes the Application server.

The OCS 2007 R2 Application Server has following services:

·         Conferencing Attendant

·         Conferencing Announcement Service

·         Outside Voice Control

·         Response Group Service

Following services are still installed on the R2 version of OCS 2007.

·         Front End Service

·         IM Conferencing Service

·         Telephony Conferencing Service

Additionally OCS 2007 R2 Front End server installs the following service.

·         QoE agent service

OCS 2007 Audio/Video bandwidth calculation

Posted by Mino on October 13, 2008

Medium Min High Quality
Data 56kbps 56kbps
Voice 50kbps 80kbps
Video 50kbps 350kbps
RoundTable (Conference video phone) 50kbps 350kbps

Note that the requirements are cumulative –

Data + Voice + Video =

56 + 50 + 50 = 156kbps (Minimum Quality)


56 + 80 + 250 = 386kbps (High Quality)”

Here are some calculations I have used. however the 300KBps is only video stream single direction.  Bidirectional video consists of two streams..

The following formula can provide rough bandwidth consumption estimates for conferencing with Audio / Video.

Note:  Calculation results will be displayed in Mbps

CC = Concurrent Conferences

PPC = Participants Per Conference


Conference Type

Bandwidth Consumption Mbps

Audio with Application Sharing

(((CC * PPC)*14KBps)+((CC *PPC)*90KBps))*10^-3

Audio and Video

(((CC * PPC)*14KBps)+((CC *PPC)*600KBps))*10^-3

Another OCS 2007 Audio Bandwidth Calculation

Audio Codec
Frame Size [ms]
Codec payload bit rate
[bits / sec]
Total payload bit rate
[bits / sec]
Actual bit rate
[bits / sec]

Microsoft OCS 2007 R2-New Version ( Updated )

Posted by Mino on October 12, 2008

There will be a new version announced in November 2008 and released in January 2009, this will be Office Communications Server 2007 R2and one major difference will be it’s transition to a 64bit ONLY platform a la Exchange 2007. This version will transpose your voicemails to text so you can still access them even if in a meeting (or the quiet car of a train..) among other new features.

OCS 2007 R2 will also have more Telephony style features including the ability to hunt groups…

There will then be a completely new version-OCS 2009/2010 (probably 2010)-released to coincide with the availability of Office 14. This along with the expected release of Sharepoint 2010, will help bring a more unified feel to the Office family. It is also expected that this new version will contain inbuilt translation services so if you receive an email in say Spanish, Exchange can read it back to you in English


Updated :

Office Communications Server 2007 R2 Features:

The most exiting feature, is the “one number calling” concept. It has been introduced in the original Unified Communications wave in the fall of 2007, but in the R2 build, it should be here. What to expect is not to say, but as I understand it will be a more simplified process of calling UC enabled users. I expect there to be more logic in OCS to how one person can be contacted.

LiveMeetin dial-in is another requested feature, which should allow users to have a choice of using the LiveMeeting client audio or dialing direct to the meeting to get Audio access.
We will see more presence information in more applications

The Communicator Web Access will be upgraded to allow application sharing the within the web application (however this is done…..)

We are also looking at an “attendant console” which will be some kind of switchboard for forwarding calls and so on. This is a feature often used by a front desk or service desk, and will give them the joy of presence information and VoIP.

Also a telephony queue system should be included, and will give people dialing in to the system, access to a touchtone menu to have their calls forwarded to the right department/person and so on.

The TAP program has started June 2008, and the new R2 version will be released to companies in the program.

The OCS 2007 R2 product should be released December 2008 or January 2009

Wave 13
This is the internal name for Office Communications Server 2007 R2 at Microsoft. The “wave” indicates that we can expect more than just e few additional features in this release, and from what i have seen and heard so far, this will be true. Wave 14??? Yes there is also a Wave 14, most likely to be OCS 2009.

Its official now. The OCS team is now openly discussing the next release on their blog, and its confirmed that OCS 2007 R2 will be 64 bit only. Rumor has it that some components might still need to be 32 bit, like the Communicator Web Access.

There has been rumors of an public beta of Office Communications Server 2007 r2, but there is none out there yet. I am not sure we will see a public beta of OCS 2007 R2, because of the limited time until its release. The current beta program is running as an TAP program (Technology Adoption) and is out there for selected customers mostly in the US. There have been inside rumors of a second program, but I’m not sure this will be public.

What is UC ?

Posted by Mino on October 1, 2008


The computer starts to work like a phone

To call someone, you just click on his or her name. The computer places the call. It doesn’t matter whether you see their name in e-mail, inside Microsoft Office Word, or on a Microsoft Windows SharePoint Services site: their contact information and the ability to reach them is always present.

Presence is one of the key benefits of unified communications because it unites all the contact information stored in Active Directory with all the ways people communicate: phone, conferencing, instant messaging, e-mail, calendaring. People’s availability, their contact information, and the ability to communicate with them are integrated and always just a click away.


The phone starts to work like a computer

Try this with a standard office phone: call someone, then add someone else to the call. Okay, now add ten people. Now, turn it into a live video call. Could you do it? Is it even possible?

With Microsoft unified communications technologies, you click to call. Click again and you can launch a conference call. Need video? It’s a click away. It’s that easy.


Voice mail becomes e-mail

Voice mail arrives in your Microsoft Office Outlook inbox, right beside your e-mail. That might not sound impressive, but have you ever tried to forward voice mail using the touchtone keypad on a telephone? When voice mail becomes e-mail, you can forward it just like any e-mail: to one person, a work team, or an entire department.


On the back end, things are even better

Change like this usually means a lot of new hardware, extra work for IT, and a vastly more complex infrastructure. But not with Microsoft unified communications technologies.


VoIP as you are

You don’t need a forklift to install Microsoft unified communications technologies because Microsoft uses software instead of hardware. Microsoft Office Communications Server 2007—the server that delivers presence, instant messaging, and audio- and videoconferencing—integrates smoothly with your existing telecommunications infrastructure, including your current PBX.


Unified communications streamline infrastructure

Microsoft unified communications technologies use Active Directory to unify the entire corporate directory—names, PBX extensions, e-mail addresses, and logons. This simplifies IT administration.


Use speech technology for self-service via the telephone

Voice portals offer callers an easy way to get to information they need using naturally spoken language from any phone, 24 hours a day, 7 days a week.

The powerful speech-enabled Interactive Voice Response (IVR), Speech Server, which is a part of Microsoft Office Communications Server 2007, can help businesses deliver significant value through speech-enabled self-service applications via the telephone at a very attractive price.

Such applications can be both inbound, like the above mentioned voice portals, as well as outbound applications, like quality surveys or notifications via the telephone.


Phone calls become digital assets

Just like e-mail. Which means they can be logged, reviewed, published, and archived. Having a complete record and recording of every phone call is increasingly critical as businesses struggle to comply with stricter federal and international regulations.


Flexible and future-ready

By using a software solution to deliver unified communications, your business can stay flexible and embrace innovations as they come. The Microsoft unified communications platform of powerful APIs enables developers to extend that software solution with security-enhanced and productivity-enhancing applications that span all modes of communications. When emerging technologies and changing business needs require your communications infrastructure to adapt, all you have to do is extend or upgrade your software, not your hardware
