After the call has been answered, there has in some cases gone up to 8-9 seconds before you can hear the person on the other side. Obviously this is quite a pain…

When trying to google the problem you get a lot of posts telling you to disable Windows Firewall. This actually solves the problem so if you are content with just disabling a firewall without knowing why, you can stop reading now.

Seems that when you install the mediation server on a Windows Server 2008 the firewall fails to open the proper UDP port negotiated during the RFC 3690 Early media negotiation until Windows Firewall detects an outgoing UDP stream. This can be solved/worked around by adding an inbound rule in the firewall that allows all UDP ports.

Thanks to JeffNye for tipping me in the right direction!

Commands to install the necessary prerequisites for OCS 2007 R2 on Windows Server 2008

Front End on Windows Server 2008
Servermanagercmd.exe -install web-windows-auth web-mgmt-compat web-mgmt-console web-http-logging msmq-server msmq-directory powershell was-process-model was-config-apis rsat-addc

Installs the following components:

  • [Web-Windows-Auth] – Windows Authentication
  • [Web-Mgmt-Compat] – IIS 6 Management Compatibility
  • [MSMQ-Server] – Message Queuing Server
  • [MSMQ-Directory] – Directory Service Integration
  • [RSAT-ADDC] – Active Directory Domain Controller Tools
  • [WAS-Process-Model] – Process Model
  • [WAS-Config-APIs] – Configuration APIs
  • [Web-Mgmt-Console] – IIS Management Console
  • [Web-Http-Logging] – HTTP Logging
  • [PowerShell] – Windows PowerShell

The last 3 in the list are not required, but they are highly recommended. IIS 7.0 Management Console is IMHO much easier to use than the IIS 6.0 version. The logging tools often come in handy when troubleshooting OCS IIS issues and PowerShell makes working with OCS WMI values a piece of cake.

Servermanagercmd.exe -install msmq-server msmq-directory

  • [MSMQ-Server] – Message Queuing Server

CWA Server on Windows Server 2008
Servermanagercmd.exe -install web-windows-auth web-mgmt-compat web-mgmt-console web-http-logging
