How it do this things :-

Lync 2010 includes a service called Location Information Service (LIS) database which, we can Identifiy the locations of users when they register based on. it using following techniques to do this.
IP Subnet

• • The IP address of the user’s PC or phone is cross-referenced to a customer-built database of where each subnet is (address, floor, etc.)
• WiFi SSID
  • The WLAN Access Point that the user is attached to is sent to Lync, which looks cross-references the location within customer-built database of where each SSID is (address, usually)
• MAC Address/Switch port (for hardphones only, not softphones/USB phones)
  • If a state (i.e. Florida) or organization mandates that they must pinpoint callers “to the station level” or cube-level, then subnet mapping is not adequate
  • Microsoft-certified phones use Link Layer Discovery Protocol to send the MAC address of the switch port that they’re connected to up to Lync when they register. They obtain their switch ID and port name directly from the LLDP frames on the Ethernet network
  • If an organization has taken the steps to map their LAN switch port locations (i.e. LAN switch MAC addresses (Lync phones report their switch ID to the LIS, which then returns the location associated to the switch id and port.
