| 1. A method for forwarding modem signals through a transport network from an originating modem to a destination point comprising:
at an originating gateway communicating with a Modem Relay Aggregator (MRA) that is located at a point in an Internet Protocol
(IP) network that is remote from the originating gateway:
receiving modem telephony signals from a circuit switched telephony network;
removing modem telephony protocol information from the modem telephony signals;
encapsulating resulting data in a transport protocol packet for use by the MRA to terminate a modem relay session;
forwarding the encapsulated packets over a Voice over Internet Protocol (VoIP) packet switched data network connection in
the IP Network;
at the MRA located at a point in the IP network that is remote from the originating gateway:
terminating a modem relay session using the encapsulated data in the transport protocol packet; and
forwarding resulting data packets through a packet data network gateway to the destination point.
