Systems and methods for obtaining in building location data for voip phones from network elements

A system for determining a location of a phone of a network device by a location information server for an emergency response location, the system comprising:

• a location information server (LIS) configured to store in a database a civic address assigned to a network device, intermediary to a plurality of phones and a call server, for an emergency response location (ERL), location information of the phone connected to the network device at the civic address to be included with the civic address for the ERL record for the phone and to be obtained from the network device;
• and
• wherein the LIS is configured to send a query to the network device to obtain information on a port from the plurality of ports of the network device connected to the phone, and in response to the query, receive from the network device location information for the port configured on the network device;
• and create the ERL record for the phone to include the location information of the port with the civic address.

A method for determining a location of a phone of a network device by a location information server for an emergency response location, the method comprising:

• (a) storing, by a location information server (LIS), in a database a partial emergency response location (ERL) record comprising a civic address assigned to a network device, intermediary to a plurality of phones and a call server, the partial ERL record to be completed with at least a location information of a phone at the civic address stored on the network device;
• (b) sending, by the LIS, a query to the network device to obtain location information on a port from the plurality of ports of the network device connected to the phone;
• (c) receiving, by the LIS from the network device in response to the query, the location information for the port configured on the network device;
• (d) completing, by the LIS, the ERL record for the phone by storing the location information of the port received from the network device with the civic address stored by the LIS;
• (e) receiving, by the LIS, a request for the ERL of the phone of an emergency caller at the civic address, the phone connected to one of a plurality of ports of the network device;
• and
• (f) providing, by the LIS, in response to the request for the ERL, the complete ERL record for handling an emergency call of the emergency caller from the phone by a public safety answering point.
