Adding ELINs to the Location Information Server

As mentioned in the previous section, the administrator needs to populate the Location Information Server (LIS) database with a network wire map, which maps the company's network elements to civic addresses. Once done, it can automatically locate clients within a network. You can add addresses individually to the LIS or in a batch using a comma-separated value (CSV) file containing the column formats for the network elements, as listed below:

Wireless access point: <BSSID>,<Description>,<Location>,<CompanyName>,<HouseNumber>, <HouseNumberSuffix>,<PreDirectional>,<StreetName>,<StreetSuffix>,<PostDirectional>, <City>,<State>, <PostalCode>,<Country>
Subnet: <Subnet>,<Description>,<Location>,<CompanyName>,<HouseNumber>, <HouseNumberSuffix>,<PreDirectional>,<StreetName>, <StreetSuffix>,<PostDirectional>, <City>,<State>,<PostalCode>,<Country>
Port: <ChassisID>,<PortIDSubType>,<PortID>,<Description>,<Location>,<CompanyName>, <HouseNumber>, <HouseNumberSuffix>,<PreDirectional>,<StreetName>,
<StreetSuffix>,<PostDirectional>,<City>,<State>,<PostalCode>,<Country>
Switch: <ChassisID>,<Description>,<Location>,<CompanyName>, <HouseNumber>,<HouseNumberSuffix>,<PreDirectional>,<StreetName>,<StreetSuffix>, <PostDirectional>, <City>,<State>,<PostalCode>,<Country>

For the ELIN number to be included in the SIP INVITE (XML-based PIDF-LO message) sent by the Mediation Server to the ELIN device, the administrator must add the ELIN number to the <CompanyName> column (shown in the table above in bold typeface). As the ELIN device supports up to five ELINs per PIDF-LO, the <CompanyName> column can be populated with up to this number of ELINs, each separated by a semicolon. The digits of each ELIN can be separated by hyphens (xxx-xxx-xxx) or they can be adjacent (xxxxxxxxx). When the ELIN device receives the SIP INVITE message, it extracts the ELINs from the ELIN field in the PIDF-LO (e.g., <ca:ELIN>1111-222-333; 1234567890 </ca:ELIN>), which corresponds to the <CompanyName> column of the LIS.

For backward compatibility, if the ELIN field doesn't appear in the PIDF-LO, the device extracts the ELINs from the NAM field.

If you do not populate the location database and the Skype for Business location policy, and Location Required is set to Yes or Disclaimer, the user is prompted to enter a location manually.
