WARNING: Do NOT change the default SIP Domain in Lync! As Microsoft wrote in the article Planning for Simple URLs , you will also see during your Topology setup, if you use multiple SIP domains, you only have one (1) active DIALIN URL. This is by design and normal. If you default SIP domain should be different from that you want to use in your simple URL. Say your default SIP domain is CONTOSO.COM, you are able to Change your DIALIN and also MEET URL to say: CUSTOMER.COM. If you need to do this, you have to add, as Best Practice, CUSTOMER.COM as additional SIP domain. Even if this domain will not be used for user SIP addressing. If you want to make those changes after certain times, meens after you deployed Lync 2013. Be Aware about the Impact. You need to change your DNS and all related certificates. 1. NEVER DELETE nor CHANGE your Default SIP Domain 2. after you changed the simple URL, you MUST run Enable-CsComputer on all Frontend and Director Servers. Author...

You for your information, with Lync 2013 some former tools are depreciated. While in LCS, OCS and Lync 2010 exporting the user data was done with the dbimpexp.exe utility. Now with Lync 2013 new EXPORT-CSxxx commands are integrated within the Lync Management Shell. Convert-CsUserData Import-CsUserData Sync-CsUserData Update-CsUserData As we now from former days, we had to use DBIMPEXP to extract the user data, e.g. the Lync buddy list, to export data directly out of the RTC database. Lync 2013 made the export functions more convenient and added PowerShell commands to do a more simplified export. With this EXPORT-CSxxx commands, you can export: User Data Conference Directories LIS (Location Information Service) - E911 Data RGS - Response Group Data Persistent Chat Data With the Convert-CsUserData command, you are able to convert former XML formats into the actual Lync 2013 format. But if you need to convert Lync 2013 data backward to Lync 2010, you need ...

A new topic came along my way, even I personally work with windows server since NT 3.5, but in very tight configured network environments you might run into server DNS resolution issues. Principals regarding Lync Edge Server DNS resolution. It is recommended to resolve DNS queries on the Internet, which means via the external NIC. For internal DNS resolution, best practice is a dedicated hosts file, or make it possible to resolve intern DNS. Therefore a common practice is to simply let even external DNS names resolve by the internal DNS servers. NOTE: Make sure you have the put in the DNS Servers on the correct network interface! What and how Windows Server really works: A we know, each IP setting for every NIC allow us to specify a DNS Server entry. As I figured out and very important to know, DNS resolution will work ONLY on the network adapter, where DNS servers are configured. While we still keep in mind, if a hosts file is used, the hosts entries are loaded int...

Amazing the actual Polycom VVX series. The first Lync Design Phone System for Lync. The VVX series has the black+white screen based models (VVX 300 / VVX 400) and the color screen models (VVX 500 / VVX 600). Another model is the executive model VVX 1500. As this is manly well know, i want to highlight the VVX extension module. This module is also available in black+white or color. What's use full is for attendants, the simple way how it can be configured. You simple need to add some more Lync user into your Lync client and it is simple sync'ed with the Expansion Module. This Unit can support 3x28 Lync users and can be expanded with 3 modules, this means you have more then 3x3x28 = 252user on the Expansion Module, plus the 15 users on the VVX 600 phone. this is quite a lot, i think. Note the VVX Camera is not yet supported with Lync, but should be quite soon. Two more features which are amazing, the "Better together over Ethernet" and the touch scree...

Today i like to show you the simple setup for Polycom's CX8000 Lync Room System First, the CX8000 is combination build with Polycom CX5100 new Round Table camera in combination with Crestron LRS components. This combination from Polycom has the advantage of a really professional camera, since Microsoft has made the requirements, that Crestrons system is only allowed to work with any Lync certified USB camera. Personally, I'm not so happy here, since a professional Video Conferencing System should make us of a professional camera instead of any Desktop cam. Additionally the system is quite expensive, another reason for need of better cameras. Since the newly developed CX5100 with 5 HD cams, this is acceptable solution. Polycom, as I was informed, is still working on a solution making use of their Eagle Eye III cam. Lets hope this will be available soon. First you need to setup up the system physically, so the cabling. Important is, you need a large touch screen. I recomme...
