ABSTRACT:
A system and method to provide emergency call access in Voice over Internet Protocol (VoIP) systems without compromising network security. The system and method enables VoIP emergency signal detection at a user device, and transmission of the VoIP emergency signal from the user node to a network server node through the use of data encapsulation and decapsulation (or “tunneling”), allowing VoIP data routing via an IP transport layer regardless of access or network security restrictions.
