Methods for emergency response location (ERL) correction in a voice over internet protocol (VoIP) 911 server and related systems and computer program products

Abstract:

Methods for ERL Correction are provided including receiving a VoIP emergency call from an emergency caller. The VoIP emergency call is identified by a unique ELIN. The ERL data associated with the unique ELIN is retrieved from a LIS using the unique ELIN. A notification is intercepted at the LIS. The notification contains both an original extension number or a DID number and the ERL data. The ERL data is matched using the ELIN to the ERL data to locate one of the original extension number and the DID number. A correct physical address is located using the original extension number or the DID number. Address data is corrected in the ERL to include the correct physical address of the emergency caller to provide a corrected ERL. The notification is reissued including the corrected ERL and the VoIP emergency call is routed to a PSAP with the corrected ERL.
