Abstract
Methods and apparatuses for routing emergency calls originated from mobile wireless devices in a Voice-over-IP (VoIP) system are described herein. In one or more embodiments, emergency calls are routed in a VoIP system by receiving incoming emergency calls originated from dual-mode mobile devices connected to the VoIP system through wireless access points (WAPs), determining locations associated with the incoming emergency calls, and redirecting callers to a cellular network. In other embodiments, emergency calls are routed in a VoIP system by mapping WAP identifiers to emergency answering points (EAPs), receiving an incoming emergency call from an originating WAP, identifying an EAP relating to the originating WAP, and directing the emergency call to the identified EAP.
