    Abstract: In a communications system for conducting a teleconference, a voice bridge is employed to establish communication connections with attendees of the teleconference. In addition, a facsimile bridge is employed to distribute facsimile data associated with the teleconference. In an illustrative embodiment, the attendees provide, through the communication connections, their facsimile numbers which may be used by the facsimile bridge to distribute the facsimile data to those attendees. Alternatively, through the communication connections, the voice bridge provides the attendees with an access number for retrieving the facsimile data from the facsimile bridge.

    Abstract: Disclosed are a method, apparatus, and system for switching from a fax channel to a voice channel. Herein, the method includes: after entering a T.38 fax, counting a first quantity of scheduling periods during which a local end does not demodulate any fax data continuously, and counting a second quantity of scheduling periods during which a remote end does not receive any T.38 packet continuously; and judging whether the first quantity and the second quantity both reach a threshold, and switching from a T.38 fax channel to a voice channel when the first quantity and the second quantity both reach the threshold.

    Abstract: An IFAX IP telephone connects a call to an opposing IFAX IP telephone via the Internet, and executes a voice call process that exchanges voice packets with the connected opposing IFAX IP telephone. When transmitting an image data to the opposing IFAX IP telephone during the voice call to the same telephone, an IFAX packet is generated, the packet having the opposing IFAX IP telephone as the destination. The IFAX packet is transmitted, while prioritizing the voice packet transmission.
