Abstract:
Systems and methods for providing E911 services to a publicly-switched telephone network (PSTN) phone are described. In some embodiments, the systems and methods determine that the PSTN phone is connected to a voice over internet protocol (VoIP) adapter, identify an internet protocol (IP) address for an access point via which the adapter accesses an IP Multimedia System (IMS) network, determine a geographical location associated with the IP address, and enable E911 communications for the PSTN phone over the IMS network via the adapter based on the geographical location.
