• Location TLV
Provides location information from the switch to the endpoint device. The location TLV can send
this information:
–
Civic location information
Provides the civic address information and postal information. Examples of civic location
information are street address, road name, and postal community name information.
–
ELIN location information
Provides the location information of a caller. The location is determined by the Emergency
location identifier number (ELIN), which is a phone number that routes an emergency call to
the local public safety answering point (PSAP) and which the PSAP can use to call back the
emergency caller.
