    摘要: A method for establishing a multimedia connection with quality of service (QoS) using an ATM backbone for ISDN network or IP network calls. QoS makes IP over ATM useful for video and audio conferencing by ensuring a minimum packet error rate at acceptable bit transmission rates. The invention will utilize the H.323 annex C protocol to transmit IP gateway transmissions through an ATM backbone network. This invention enables H.320 endpoints having a connection to an ATM network to send QoS communications to other endpoints. When call setup is initiated between two endpoints, an ISDN (or IP) call is sent to a gateway. The gateway will utilize a network gatekeeper to route the call to the addressed endpoint's corresponding gateway. When a route is established, the call will be converted to an H.323 annex C protocol transmission and sent through the ATM backbone to the destination gateway. At the destination gateway, the call will be converted to another protocol (as necessary) for delivery to the destination endpoint.

    摘要: The present invention is a system, apparatus and method for voice over Internet protocol telephone (VoIP) calling using enhanced SS7 signaling packets and may include localized time slot interchanging. A system embodiment of the invention includes originating and terminating VoIP gateway switches in communication with the public switched telephone network (PSTN) and also in communication with an IP-based packet network, such as the Internet, for transmitting packets. The VoIP gateway switches are configured to exchange enhanced SS7 signaling packets over the IP-based packet network for setting up and tearing down VoIP telephone calls. A method of placing a VoIP telephone call in accordance with the present invention includes initiating a telephone call to a destination and connecting the telephone call to an originating VoIP gateway switch using enhanced SS7 signaling packets. The method also includes determining a preferred route from the originating VoIP gateway switch to the destination through an IP-based packet network and through a terminating VoIP gateway switch nearest said destination, and setting up two-way communication through the preferred route using the IP-based packet network using enhanced SS7 signaling packets.

    摘要: Methods and apparatus of managing a communication system, wherein a decision regarding a level of activity at a first end is made based at least in part on the level of activity at the second end. In one embodiment, the energy level of a first-end audio signal is measured. The first end is declared voice-active if the first-end energy level is greater than or equal to a first threshold value. The first end is declared voice-inactive if the first-end energy level is less than the first threshold value. To determine the value of the first threshold value, the energy level of a second-end audio signal is measured. If the second-end energy level is greater than or equal to a second threshold value, the second end is declared voice-active, in which case the first threshold is maintained at a relatively high level. If the second-end energy level is less than the second threshold value, the second end is declared voice-inactive, in which case the first threshold is maintained at a relatively lower level.

    摘要: A method of and system for telecommunication are disclosed, in which a service provider establishes a point of presence with a plurality of telephone numbers in at least one first vicinity. The service provider receives telephone calls to those numbers and relays each such call over a wide-area network (WAN) to a recipient in a second vicinity to which the telephone number in question is not local. Each said telephone number is assigned to a specific recipient, and each call is directed to its recipient on the basis of the telephone number to which it was made, so that each number can be presented to potential callers as if it were a local number in the first vicinity for the recipient, even though the recipient may have no physical presence in the first vicinity. The recipient thus has a nullVirtual Telephone Numbernull (VTN) in the first vicinity. The caller need merely telephone the local number in his or her own vicinity, and is connected to the recipient without any further action or effort on the caller's part.

    摘要: A method for transmitting voice data over various types of networks wherein user data are transmitted via a transmission link of a circuit-switched network and are distributed to data packets and forwarded via a packet transmission network if the user data are typical of voice transmission. If, in contrast, the user data are typical of silence intervals, no user data are forwarded via the packet transmission network. The type of connection is determined in a signaling unit.
