Trouble dial forreign countries from Lync with SIP trunk

I have noticed some trouble due to timeout when calling abroad.
What I have done that fixed this problem was:

Configuring Parameters
Some of the above timeouts can be configured. The file which has the configurable parameters is 'OutboundRouting.exe.config”  Use caution when changing these values, as a rule of thumb try not to increase or decrease the value by more than 25% of its original value.

from OutboundRouting.exe.config
      <add key="FailOverTimeout" value="10000"/>
      <add key="MinGwWaitingTime" value="1"/>
      <add key="MaxGwWaitingTime" value="20"/>
      <add key="FailuresForGatewayDown" value="10"/>
      <add key="FailuresForGatewayLessPreferred" value="25"/>
      <!-- Valid values are between 5 and 600 -->
      <add key="HealthMonitoringInterval" value="300"/>
      <!-- Valid values are between 60 and 3600 -->
      <add key="GatewayStateReportingInterval" value="1800" />

The FailOverTimeout should be increased to the desired time limit.
The file is found under C:\Program Files\Microsoft Lync Server 2010\Server\Core

Change this from 10000 to 20000 (20 sec). Save the file and reboot the frontend server.
<add key="FailOverTimeout" value="20000"/>


Office Web app Server

One of the new things thats comes with Lync 2013 is Office Web App Server.
So what is this, and that is a good question to ask. Do I need this??
This is a part of the topology builder and it ask you if you have a Office Web App server already running in you network. If not, well then you have to install a new one if you want.

From the deployment document we can read this:

In Microsoft Lync Server 2013 Preview PowerPoint presentations were viewed in one of two ways. For users running Microsoft Lync 2010, PowerPoint presentations were displayed using the PowerPoint 97-2003 format and were viewed using an embedded copy of the PowerPoint viewer. For users running Lync Web App, PowerPoint presentations were converted to dynamic HTML files then viewed using a combination of those customized DHTML files and Microsoft Silverlight. Although generally effective, this approach did have some limitations:
  • The embedded PowerPoint Viewer (which provided the optimal viewing experience) is only available on the Windows platform.
  • Many mobile devices (including some of the more popular mobile phones) do not support Silverlight.
  • Neither the PowerPoint Viewer nor the DHTML/Silverlight approach support all the features (such slide transitions and embedded video) that are found in the more recent editions of Microsoft PowerPoint.
To help address these issues, and to improve the overall experience of users presenting or viewing PowerPoint presentations, Lync Server 2013 Preview employs Office Web Apps and the Office Web Apps Server to handle PowerPoint presentations. Among other advantages, this new approach enables:
  • Higher-resolution displays and better support for PowerPoint capabilities, such as animations, slide transitions, and embedded video.
  • Additional mobile devices to access these presentations. That's because Lync Server 2013 Preview uses standard DHTML and JavaScript to broadcast PowerPoint presentations instead of customized DHTML and Silverlight.
  • Users with the appropriate privileges to scroll through a PowerPoint presentation independent of the presentation itself. For example, while Ken Myer is presenting his slide show, Pilar Ackerman can look at any slide she wants to, and without affecting Ken's presentation.
But there is more, you can use Sharepoint2013 to communicate with Office Web App Server. So there might be a good way when RTM comes out to start to plan for this environment.
I have not found any "server spesifications" yet, so if anyone out there has something please inform me...........

Cool feature in the Lync Client

I have installed Lync 2013 preview client form Office2013 preview running on my Windows 7 X64. The Lync environment on server side is still Lync2010 .
But when I join meetings I will if I have or can see picture of those who are in the meeting, name on who is speaking.
Great feature, just love it :-)


Lync Client 2013

The Lync client for 2013 is working fine with Lync 2010 server. I have tested it for 1 week now and evrything works as I expected. I have used it to conferencing, dialin, desktop shareing.
Evrything works just as I was waiting.
Lost calls is even logging in Outlook.


Lync Certificates

As we know Mircosoft say that *.domain.com (wildcard certificates) is not supported under Lync.
This is also the issue under Lync 2013 preview.
Documentation from Microsoft say's its ok to use wildcard certificates on TMG/UAG reverse proxy.
If you plan to use Polycom with Lync Phone Edition on any versions of Lync, please do not think about useing wildcard certificates. And not on the "frontend server" and on the internal NIC for Edge. This will give you trouble download the certificate to your Polycom device.
For the internal NIC of Edge server and for the "frontend" server use certificate from the PKI server.
