PIDF-LO

Created by Kelly Evans, Modified on Fri, 31 Jan at 9:58 AM by Kelly Evans

The Presence Information Data Format - Location Object (PIDF-LO) provides the geographical location of a presentity. This corresponds to a physical location at a given instance of time. PIDF-LO provides an XML formatted “location object” that is included in the SIP Invite of an emergency call to provide the location information. PIDF-LO supports dynamic location routing (DLR).

Microsoft Teams supports dynamic location routing by including a PIDF-LO XML object in an Emergency Call’s SIP Invite.

The Method Field in the PIDF-LO XML object defines the Type of emergency address and how that type of address should be routed.
