    摘要： A call transfer may be prompted by a first endpoint, from the active status—open bearer channels between the first endpoint and a second endpoint—in a communications network based on ITU-T Standard H.323. The call transfer is effected by a series of steps, namely a facility message for call transfer, including an address for the third endpoint, is transmitted to a proxy function; a connection setup message is transmitted from the proxy function to the third endpoint and the third endpoint responds by transmitting a call connect message to the proxy function; the connection between the first endpoint and the second endpoint is released; and the proxy function initiates a connection to be set up between the second endpoint and the third endpoint.

    摘要： A line group function in a communications network based on ITU-T H.323 is implemented via a proxy function. First, an alias address for the line group is converted into a group transport address for a proxy function, and a connection setup message is transmitted from the calling endpoint to the proxy function using the group transport address. A connection setup message is transmitted from the proxy function to group endpoints in the line group using transport addresses known to the proxy function. After a response message has been transmitted from one of the group endpoints to the proxy function, the address of this endpoint is transmitted to the calling endpoint, and the address of the calling endpoint is transmitted to the responding group endpoint by the proxy function. A connection is set up between the calling endpoint and the responding group endpoint using the addresses of these endpoints.

    摘要： A queue server is established in a packet telephony environment, wherein the queue server is defined as a callable entity, separate from the H.323 workstation for which it is being used. The queue may be used with any piece of H.323 software without modification to the software. All that need be done is the configuration that is typically accomplished when H.323 software is installed on the workstation. For example, the queue may be identified as a callable entity to receive call forwarding from the busy device or endpoint. The H.323 software of the endpoint needs to be able to handle only one call at a time, thereby reducing memory requirements for the equipment.

    摘要： A system and method in an H.323 network for automatically reestablishing signaling that was interrupted due to gatekeeper failure. Primary and secondary gatekeepers (104a, 106a) establish a supervisory link (1b) with one another while the media connection is set up between client terminals (112a, 114a). The primary gatekeeper (104a) also establishes the H.225/H.245 signaling between the client terminals. If the primary gatekeeper (104a) fails, the H.225/H.245 connections go down, but the media connections will continue. The secondary gatekeeper (106a) than takes over the call and sends a message to its zone's clients that the H.225/H.245 connections need to be reestablished. Further, the secondary gatekeeper (106a) sends a message to the other zone's gatekeeper (if any) of what has occurred. The clients then reestablish the H.225/H.245 channel by using the original setup message with a new Reestablish parameter. The receiving client receives the message, re-establishes the signaling connection and continues using the existing media channel for the media stream of the call.

    摘要： A method and a system of providing call progress tones in a packetized network include storing the call progress tones and pre-programmed audio deliveries at a first device and includes multicasting or broadcasting the tones and deliveries from the first device to a number of telephony-enabled devices. The multicasts are in a format that enable the telephony-enabled devices to individually control transmissions of the tones and deliveries to other devices, particularly calling devices for incoming calls. Typically, the audio deliveries include memory intensive signals, such as announcements and music-on-hold. The progress tones include conventional call status tones, such as ringback, busy and error tones. In one embodiment, the telephony-enabled devices are telephones to which the calls are directed. In another embodiment, the telephony-enabled devices include proxies that process the system-wide multicasts for telephones of the network. Optionally, all of the tones and deliveries may be multiplexed into a single data stream. The multiplexed multicast data stream is then processed when a particular tone or delivery must be extracted. Optionally, less frequent announcements can be multiplexed into a generally continuous data stream for periodic presentation to a particular type of caller, such as a periodic selection of a particular message that interrupts music-on-hold. In another possible modification, the data stream is not processed at a called telephone. Instead, the called telephone directs the selected multicast to the calling telephone, which provides the processing.

    摘要： An automatic call distribution system utilizes a number of H.323 compatible devices. An automatic call distribution (ACD) server (52) interfaces with a computer telephony interface gateway (54) to route calls to agents or to a music/video server (56). Calls are received by a gateway and supplied to a gatekeeper that determines an IP address of the destination. The ACD server selects the destination in response to the number of agents available. In addition, customer calls can be received via e-mail, facsimile or the Internet. The call distribution system can instruct an agent to return an e-mail or facsimile message or to call a customer if desired. Calls from one H.323 device can be routed to another H.323 device by a third party application by sending a call control message to the device's application program interface that executes the message as if it were generated at the device itself.
