Abstract
The invention discloses an IP telephone communication system including a first communication device and a second communication device. When a user uses the first communication device to communicate with the second communication device, the first communication device will transmit an initial signal to the second communication device via a first communication channel. After receiving the initial signal, the second communication device will transmit a DTMF signal back to the first communication device via the first communication channel. When the first communication device receives the DTMF signal, an IP address of the second communication device will be obtained by decoding the DTMF signal. Afterward, according to the IP address, the first communication device is capable of communicating with the second communication device via a second communication channel in VoIP.
