Abstract: Techniques are described for obtaining current location data for a non-traditional telephony endpoint for emergency calling purposes. An emergency services (ES) provider receives, from a telephony server responding to a telecommunication session establishment request from a telephony endpoint, a location registration request, the location registration request including telephony endpoint identification information and a mobile device telephone number. The ES provider may send a short message service (SMS) message to the mobile device telephone number, the SMS message including an executable registration link that when executed on a mobile device receiving the SMS message causes the mobile device to retrieve location data of the mobile device. The ES provider may then receive the current location data from the mobile device and store it and the telephony endpoint identification information for subsequent use should a 911 call be made from that telephony endpoint.

Abstract: Techniques are described for obtaining current location data for a non-traditional telephony endpoint for emergency calling purposes. An emergency services (ES) provider receives, from a telephony server responding to a telecommunication session establishment request from a telephony endpoint, a location registration request, the location registration request including telephony endpoint identification information. The ES provider may push a quick response (QR) code to the telephony endpoint, the QR code when scanned by a mobile device causes the mobile device to retrieve its current location data. The ES provider may then receive the current location data from the mobile device and store it and the telephony endpoint identification information for subsequent use should a 911 call be made from that telephony endpoint. The ES provider may then send the telephony server an authorization acknowledgement for the telecommunication session establishment request.

Abstract: Techniques for customizing an audio response to emergency test calls are provided. The technique includes receiving a Voice over Internet Protocol (VoIP) emergency test call from a test call device by an emergency service (ES) provider. Call information specific to the VoIP emergency test call is obtained from an ES provider customer database associated with the ES provider. The obtained call information specific to the VoIP emergency test call is provided to an emergency test call audio generation server. A customized audio response to the VoIP emergency test call is generated and returned to the test call device based on the provided call information specific to the VoIP emergency test call using text-to-speech technology.

Abstract: Disclosed are techniques for handling emergency calls via an emergency call routing system. A Voice-over Internet Protocol (VoIP) emergency call server may be configured to receive a session initiation protocol (SIP) INVITE for an emergency call from a telephone number serviced by a telecommunication service provider (TSP) SIP call server. The SIP INVITE message header may include multiple location objects including a registered geo-coded address location object associated with the telephone number placing the emergency call, and a location object comprised of lat-long coordinates determined at the time the emergency call is placed. The emergency call server may determine whether the registered geo-coded address and the lat-long coordinates are within a specified distance of one another.

Abstract: Embodiments of the present invention relate generally to methods and systems for validating location information and more particularly to validating an address associated with a communication identifier such as a telephone number which can be used, for example, to handle an emergency call placed from that telephone number. Generally speaking, embodiments of the present invention can include a validation process for location information received during registration of a subscriber of a communication service. The registration information can comprise a telephone number and an address. In one example, the received address can comprise a United States Postal Service (USPS) standard address while the validated address can comprise a Master Street Address Guide (MSAG) valid address.

Abstract: Embodiments of the invention provide systems and methods for handling emergency calls. According to one embodiment, handling an emergency call can comprise receiving an emergency call from a calling number, determining whether the calling number has been ported from an original geographic location to a new geographic location, determining a spatial location for the calling number based at least in part on whether the calling number has been ported, identifying a public safety system for handling the emergency call based on the determined spatial location for the calling number, and routing the emergency call to the identified public safety system. Identifying the public safety system for handling the emergency call can comprise using a point-in-polygon check of the determined spatial location for the calling number against known spatial boundaries for a plurality of public safety systems.
