Abstract

Various methods and systems for establishing modem relay connections are provided. For example, a modem relay method for use by a first gateway device in communication with a calling modem comprises the exemplary steps of: receiving a call from the calling modem for establishing a communication with a remote modem; requesting a second gateway device to place a call to the remote modem for establishing the communication; transmitting ANSam to the calling modem for a predetermined period of time according to an ANSam message received from the second gateway device in an RFC2833 message via a packet network; monitoring for detection of a CM signal from the calling modem; monitoring for detection of an AA signal from the calling modem; monitoring for receipt of a modulation type message from the second gateway device; and monitoring for receipt of a pass through mode message from the second gateway device.
