Abstract
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.
