International Classification:

H04L 1266

US Classification:

370352, 370353, 370355

Abstract:

A telephone call from first telephone device to a second telephone device is initiated by a call directly from the first telephone device to a first gateway. The first gateway receives dialed digits from the second telephone device, identifies an address on a packet switched network of a second gateway associated with the second telephone device, which identified by the dialed digits. The first gateway contacts the second gateway via the packet-switched network. The second gateway initiates a circuit-switched telephone connection to the second telephone device. When a ringing signal or busy signal is received from the second telephone device by the second gateway, the second gateway provides a signal via the packet-switched network to the first gateway. The first gateway provides the corresponding signal to the first telephone device.

Abstract:

A server, upon receiving a request to complete a call over a packet-switched network, looks up an address on the packet-switched network on a local table. If the local table does not contain a matching address, the server asks a routing server to identify a receiving server address. The routing server identifies a suitable address and sends a message to the originating server containing the address. The routing server may consider such factors as the volume of calls currently being handled by various potential receiving servers in selecting a receiving server. The receiving server then receives, via the packet-switched network, a message requesting a telephone connection to a second telephone device. Before completing the connection to the second telephone device, information in the message representing the address of the device on the packet-switched network that originated the message is identified. The address information is compared to selected predetermined addresses for permitted origins of the message.

Harvey S. Schultz - Manalapan NJ

Assignee:

AT&T Bell Laboratories - Murray Hill NJ

International Classification:

H04M 1100

US Classification:

379100

Abstract:

A facsimile (fax) machine is arranged to automatically answer a call and to transmit a fax message if a document or stored message is awaiting transmission, otherwise the fax machine goes into a fax receive mode. In another arrangement, the fax machine is connected to a station port of a customer switching system such that an existing call at a system station set can be transferred to the fax machine when a fax message is to be transmitted or received as part of that call. In one embodiment a station set and fax machine are packaged together in one housing.

Before completing the connection to the second telephone device, information in the message representing the address of the device on the packet-switched network that originated the message is identified. The address information is compared to selected predetermined addresses for permitted origins of the message. The permitted origins may be other servers or clients of the receiving server. If the address in the message corresponds to a predetermined permitted address, the server will proceed with completion of the call. If the address in the message does not correspond to a predetermined permitted address, the server will refuse to complete the call.
