For IP telephones, SIP-enabled telephones, or Softphone, all of which do not have a physical connection to the Messaging server or gateways but access the communications system over the LAN, Messaging uses the subnetwork to identify the location of the telephone. Messaging then converts this location into an Emergency Location Information Number (ELIN) and passes the ELIN on to the PSAP. For Softphone only, Messaging also allows the user to enter a phone number which the PSAP can then use to identify the user’s location during an emergency call. For some types of E911 locating capabilities, the Cielo E-911 Manager from RedSky Technologies, Inc. offers more precise location capabilities. Contact RedSky for more information about how that product interacts with Messaging E911 capabilities. The website for RedSky Technologies, Inc. is http://www.redskytech.com.
