Lync Server Documentation Update on April 2011

May 02, 2011 By: Yann Espanet Category: KB articles, Lync, Whitepapers

New Documentation and Tools Available

Updates to existing topics

Certificates and Wildcards

In addition, we clarified some of our guidance around certificates and wildcards. Lync Server 2010 supports wildcards only in the SAN and not the subject name.

For more details, see the following topics:

Migration Updates

Operational Guidance

New topics about Lync Server Control Panel have been added to the Operations, Planning, and Deployment sections of the documentation. The documentation now includes tips to troubleshoot access to Control Panel. To accommodate these and other updates to software requirements, permissions, and procedures for administrative tools installation, we added some new topics, as well as restructured other topics and sections. For details, see the following topics:

We also updated information about Enterprise Voice branch-site resiliency to address recommendations regarding policy and dial plan configurations for different routing scenarios, as well as guidelines for handling call rerouting in outage scenarios, particularly for phone numbers that include extension numbers. For details, see:

Topics about creating Quality of Service (QoS) policies were updated to include the executable names for components for which you can enable QoS. For details, see:

The recommendations for choosing between deploying Survivable Branch Appliances or Survivable Branch Servers for branch-site resiliency have been updated. For details, see the following topic:

The procedure to enable QoS on Windows Server 2003 and Windows XP now specifies that you use Group Policy to modify default Differentiated Services Code Point (DSCP) values. The topic now also includes the default DSCP values for the IP packets for audio and video. For details, see the following topic:

The time interval that you can configure Lync 2010 to wait between connection attempts to Lync Server 2010 have been corrected to state that the accepted values are between 1 minute and 60 minutes.

Planning Updates

The Planning documentation for Enterprise Voice now contains additional clarification about requirements and recommendations for Mediation Server topologies. For details, see:

Enterprise Voice content was also updated to remove references to dual-forking to reflect that dual-forking is not supported in Lync Server 2010.

Clarification has been added to various topics that refer to the Enterprise Voice media bypass feature to explain that media bypass does not interoperate with every PSTN gateway, IP-PBX or SBC, also known as peers of the Mediation. Media bypass is supported only with products and versions listed at Unified Communications Open Interoperability Program – Lync Server.

Deployment Updates

Deployment documentation has been updated to specify that server in-band provisioning settings take precedence over settings configured by the user on the client. For details, see the following topic:

March Updates

In case you missed the March updates, they included the following:

In addition, we corrected the following errors found in our documentation:

  • We corrected our guidance on deploying Edge Servers. Previously, our documentation said that deploying Edge Servers in an Active Directory domain was not supported. That was an error. This is now corrected in the Deployment Best Practices for External User Access topic.
  • We also clarified the SQL Server database collocation and database instances. The supportability topics and all other topics referencing database collocation are now updated.
