摘要： A system and method for providing Quality of Service in an Ethernet network. One or more telephony application programs are provided, along with an H.323 Recommendation stack (101a), an IP layer (114), and preferably modular Generate QoSEthernet (118) and QoSEthernet layers (115). The Generate QoSEthernet layer (118) is adapted to read Type of Service or Differentiated Service bytes (502, 602) and generate desired QoSEthernet commands therefrom. Either the Generate QoSEthernet layer (118) and/or the QoSEthernet layer (115) may be replaced and/or modified without necessarily having to modify the H.323 Recommendation stack and application program(s).

摘要： A bandwidth adjustment server, BWAS 109 is provided which monitors system bandwidth usage, sends requests to terminals 102A, 102B and/or 106, to identify their coding capabilities, and directs each of the terminals to adjust their coding algorithms based on system bandwidth usage. If system bandwidth usage is high, the BWAS 109 requires the terminals to employ a less bandwidth intensive coding algorithm; similarly, when system bandwidth usage is low, the BWAS 109 will allow the terminals to employ higher bandwidth use coding algorithms.

摘要： A method and system for providing security for a computing device include resolving, conflicts between a password-protected screen saver and communication notification capabilities by selectively enabling access to specific communications when the computing device is in a locked mode. The screen saver of the computing device is configured to switch the device from a normal operative mode to a locked mode in response to detection of a preset condition, such as the expiration of an idle-time timer. The computing device then remains in the locked mode until a preset authorization condition is recognized, e.g., entering a password. However, with the computing device in the locked mode, a subset of communication access capabilities is enabled. Specifically, notification of incoming communications is enabled. Preferably, connectivity for select types of outgoing calls is also enabled, e.g., connectivity for emergency calls. In the preferred embodiment, the conflicts are resolved by integrating the screen saver with communication access capabilities in a single software package. Also in the preferred embodiment, the communication access capabilities are provided by a telephony over LAN application and a switch to the locked mode is disabled during communication sessions involving the computing device.

摘要： Techniques for validating an audio configuration of a computer are provided. Validation tests are performed on the audio configuration and results from the tests are displayed to a user as a report. The report can include an indication of the audio configuration settings that will adversely affect the audio quality for such uses as computer telephony. Additionally, the report can indicate a recommendation on changing the audio configuration to improve audio quality and can assist the user in making the audio configuration change.

摘要： In a system and method according to the invention, a gateway 106 to an H. 323 network is configured to monitor and intercept in-band signaling from external networks. The gateway 106 further provides to the H.323 terminal 102 out-of-band signaling indicative of the nature of the in-band signaling received from the external network. If the signaling changes, the gateway 106 provides this information to the H.323 terminal 102. The gateway 106 thus prevents the need to cut through audio channels for ringback tones or busy signals.

摘要： A method and system for establishing and managing subconference calls within a main conference call includes a subconference call subsystem (30) which responds to a subconference call request (28) from a first terminal (14) during the main conference call by transmitting (58) the subconference call request to a second terminal (24). The subconference call subsystem monitors (30) a connection to the second terminal to detect a signal indicating acceptance of the request. Upon detecting an acceptance, the subconference call subsystem establishes (62) a first subconference call and a data mixer (34) mixes (66) first voice data (42) from the main conference call with simultaneously transmitted second voice data (38) generated from the first and second terminals. A data router (36) transmits (68) the mixed first and second voice data (40) to the first and second terminals without transmitting the second voice data to any of the other terminals participating in the main conference call. Furthermore, the process of establishing subconference calls is transparent to the other main conference terminals. The subconference call terminal can establish (73) a second subconference call and can switch (80 and 82) the terminal for bi-directional voice transmissions within the main conference call, the first subconference call, or the second subconference call.

摘要： A method and system for exchanging electronic messages, such as email messages, include isolating personal computers and other client devices from the process of converting a message attachment from one file format to a second file format. File-format conversions are out-tasked to enhance file accessibility, free computer resources, and conserve a user's time. The access requirements of each attachment to electronic messages are compared to the capabilities of a target client device. If it is determined that a file-format conversion is required, the conversion operation is assigned to a server that supports the process of reformatting the attachments. In an email environment, the server is substantially equivalent to the conventional email server, but includes enhanced conversion capabilities. In one embodiment, the determination of whether an attachment is accessible without conversion occurs at the server level. In another embodiment, the determination is implemented at the client device level. Preferably, if a local email server is incapable of reformatting the attachment, a request is transmitted to a remote server to perform the conversion. Typically, the remote server is the email server that supports message exchanges for the person who originated the message.
