Abstract:
1. A method for terminating a modem session for transporting data across a voice-over-Internet Protocol (VoIP) network using a modem relay (MR) technique, the method comprising: receiving a modem session packet over a first packet-based network from an originating gateway without handshaking and without sending an indication of an ANSam tone to the originating gateway over the first packet-based network, the modem session packet to transport data represented by modem signals from a client modem in demodulated form; removing from the modem session packet, headers associated with transporting the data over the first packet-based network; terminating the modem session and making the data available for further transport over a second packet-based network; encapsulating the data in an Internet Protocol (IP) packet with a destination address of an IP device for further transport over the second packet-based network; and delivering the IP packet to the IP device over the second packet-based network.
