1. A method for Enhanced Dynamic Emergency Location Routing (E-DLR), the method comprising:
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;
determining that the associated address is a shared address based on information in a geolocation record, wherein the shared address is not a home address associated with the roaming emergency caller;
routing the emergency call from the roaming emergency caller to a public safety answering point (PSAP) associated with the second country using a proxy TN associated with the shared address, wherein receiving is preceded by provisioning TN and address data associated with the roaming emergency caller in a location information service (LIS) associated with a VoIP Carrier and automatic location identification (ALI) databases associated with one or more public switched telephone networks (PSTNs);
receiving the emergency call at the PSAP associated with the second country; and
displaying the proxy TN and shared address associated with the proxy TN without use of a VoIP position center (VPC).
