Methods for Enhanced Dynamic Emergency Location Routing (E-DLR) are provided. The method includes receiving a Voice over Internet Protocol (VOIP) emergency call from a roaming emergency caller associated with a first country having an associated telephone number (TN) and an associated address, the VoIP emergency call being made in a second country, different from the first country. It is determined that the associated address is a shared address based on information in a geolocation record. The shared address is not a home address associated with the roaming emergency caller. The emergency call is routed from the roaming emergency caller to a public safety answering point (PSAP) associated with the second country using the proxy TN associated with the shared address.

Methods for providing a call-back number for emergency calls initiated from a non-DID device are provided. The methods include receiving a call from a public safety answering point (PSAP) at an application programming interface (API) associated with a carrier, wherein a PSAP operator calls a proxy call-back number on a PSAP screen that has been previously assigned to a non-DID device; requesting instructions at the API from a control function based on the proxy call-back number dialed by the PSAP operator; receiving information at the API related to the non-DID device from the control function based on pre-provisioned data associated with the proxy call-back number; and routing the call from the PSAP to the non-DID device through a voice over internet protocol (VOIP) switch.

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.

Techniques for providing SOS call routing for emergency calls are disclosed. One example system includes a first computing device that receives a message including identification information from a telephony endpoint; and retrieves location information for an IoT device based on the message. The system includes a second computing device that receives a call from the telephony endpoint that includes call information. The first computing device receives a notification of the call from the second computing device that includes the call information; verifies the call is associated with the message based on the identification information and call information; and generates instructions for the second computing device that includes forwarding the call using the location and callback information to a public safety answering point (PSAP). The second computing device receives the instructions from the first computing device and forwards the call with the emergency information to the PSAP, which services a location of the IoT device.
