Lync 2010 with CU1 introduced the LIS for identifying the Users Location for E-9-1-1 call and internal information too. The E-9-1-1 Service must be supported by a) SIP Trunk Provider or/and b) Law. What does Law mean?   Simply explained, if you are for example in Germany, so need to ensure you can make Emergency Calls also during Power Interruption. This cannot be done with Computer based Systems. A PABX is different, there are service ensuring the phones availability. So let look into LIS itself: The information will be stored in the LIS Database for Lync, which is the same for Lync 2010 and 2013.

This may mean configuring DHCP relay agents to forward DHCP packets to DHCP servers on the Registrar.   DHCP Options which are requred: Option 120 (SIP Servers) is defined in RFC 3361. It is used to return a list of SIP servers. Option 55 is used by the device to ask the DHCP server for the values of specific options (in our case 120 and 43). Option 60 is used by the client to specify the vendor f

Now it's time for the for the fir Lync 2013 site. I'm following up with the Topology blog i released earlier. I prepare the first Enterprise Server Lync 2013. Just in the Test Lab, I don't have the Load Balance yet, so what I did was, I gave the only EE Server two IP addresses. The second one is for the POOLLEFT, this is a supported scenario if you only have single pool server in place. First we need all the Pre-Requisites for the new EE Server in place, which I have listed here: PowerShell 3.0 PowerShell 3.0 is not a standalone product, it's part of the Windows Framework 3.0 http://www.microsoft.com/en-us/download/details.aspx?id=34595 .Net Framework 4.5 http://www.microsoft.com/en-us/download/details.aspx?id=30653 Windows Identity Foundation http://www.microsoft.com/en-us/download/details.aspx?id=17331 IIS Windows Desktop Experience SilverLight 4 Visual C++ 11 x64 Active Directory Management tools IIS: Static Content Def
