No Name Appears When Callings from OC to Cisco or vice versa

Posted by Mino on August 10, 2009

One of the frustrating drawbacks when Implementing OCS enterprise voice integrating with Cisco Call Manager or other PBX is that No name would appear in Communicator 2007 when a telephone user calls a Communications Server 2007 user or vice versa .

The only solution by then was to place a media gateway in the middle between mediation and IP-PBX and use a translation feature built in the media gateway to edit the packet header and add Caller Name before sending it to the PBX.

But Finally Microsoft has listened to my prayers and they have released July fix for OCS 2007 R2, once they were released our team started to do the testing in our LABs. At the beginning things didn’t work fine but in the end it worked and it appeared that we only applied the server side updates while the KB 971844 includes Office Communicator update too.

However, even with these fixes, this don’t send display name by default. So, this configuration in KB 972721 will be also necessary. Below are the snapshots taken by our Engineer Amr Nassar who has worked on this and successfully made it work after applying those Fixes.

But let me also share Microsoft explanation on why this problem happens in the first place and what these updates fix?

Problem Explanation:

When a Private Branch Exchange (PBX) telephone user calls a Microsoft Office Communications Server (OCS) 2007 R2 user, the calling party name that exists in PBX is stripped at the OCS 2007 R2 Mediation Server. Because the PBX telephone user does not exist in Active Directory, no name appears in Microsoft Office Communicator 2007 R2

This problem occurs because the OCS 2007 R2 Mediation Server does not forward the display name information from the Unified Communications (UC) side to the gateway side. Therefore, the Communicator 2007 R2 client does not receive the display name information.

Update 970679 introduces functionality for the Mediation Server role of Communications Server 2007 R2 to forward Display Name information that is part of the From header between its gateway side and its proxy side.

A file called MediationServerSvc.exe.config should be created in the Mediation Installation Directory which be default is at  %programfiles%\Microsoft Office Communications Server 2007\Mediation Server

This file should contain.

<?xml version=”1.0″ encoding=”utf-8″ ?>
<configuration>
                 <appSettings>
                                <add key=”forwardDisplayName” value=”True” />
                 </appSettings>
</configuration>

New Microsoft Office Communicator Mobile 2007 R2 Update

Posted by Mino on August 5, 2009

The Windows Mobile version of Office Communicator 2007 R2 has just been updated. Communicator Mobile is strongly positioned as a desktop replacement application allowing OCS-enabled users to receive and place work calls over a mobile phone, exchange instant messages, and keep their presence indicators up-to-date while on the road.

This new version is available now and will be also compatible with the soon-to-be-released Windows Mobile 6.5, offering even richer integration to its users.

includes additions such as the Join Conference feature, where instead of dialing in and entering complicated conference entry codes, users can now join a meeting with the click of a button. This capability is available for all types of meetings that are scheduled using the new UC Conferencing capability in Microsoft Office Communications Server 2007 R2.

 What’s new?

Communicator Mobile 2007 R2 update is far more than a standard QFE, with several new key features:

  • Click-to-join conferences!  No more pesky dial-in numbers or passcodes to remember!
  • A better Call via Work experience, where callbacks are automatically accepted.  Just click Call via Work, and place the phone to your ear.  After a quick call setup, you’ll be connected!
  • Support for new Windows Mobile Homescreens, on Windows Mobile 6.5 and higher devices.
  • The ability to call any number via Work, on Windows Mobile 6.5 and higher devices.  This means that you can even dial extensions from your mobile phone!
  • Detection for when the phone is roaming:  by default, Communicator does not sign in to roaming networks.
