Abstract
There is provided system and method for communication over a network, which includes a first gateway and a second gateway capable of communicating with each other using a packet protocol. Further, the second gateway is capable of communicating with a communication device, such as a modem device or a facsimile device, over a telephone line. The second gateway receives a call request from the first gateway for the communication device. In response to such call request, the second gateway places a call to the communication device over the telephone line. Next, a tone detector is enabled to detect a tone, such as an answer tone generated by the modem or facsimile device. Second gateway detects the answer tone received from the communication device over the telephone line and enables a filter, in response to the detection of the answer tone, to prevent the answer tone from reaching the first gateway.
