Abstract: A mechanism is provided for enabling subscribers of an enhanced communication system to switch endpoints during a conversation, add or remove modalities, invite new participants while continuing the conversation seamlessly. Active endpoints associated with a participant in a conversation may publish their states to a managing server and become aware of a status of the ongoing conversation. Subsequently, the participants may seamlessly switch to another endpoint and continue the conversation using the other endpoint.

Abstract: Techniques for managing dual-channel wireless devices are described. A dual-channel wireless device may comprise a first transceiver operative to communicate control information over a data channel using a packet-switched network. The dual-channel wireless device may further comprise an enhanced call module communicatively coupled to the first transceiver, the enhanced call module comprising a back-to-back user agent operative to establish a session between the back-to-back user agent and a call terminal using the control information. The dual-channel wireless device may also comprise a second transceiver operative to communicate voice information over a voice channel using a circuit-switched network during the session. Other embodiments are described and claimed.

Abstract: A control server initiates a call to a first device. After creating a connection to the device, the control server reverses the direction of the message flow between the device and the control server such that the device becomes the initiator of the call (the caller) and the control server becomes the device that is called (the callee). A connection is also established between the first device, the control server and a second device that is an endpoint for the call. Early media and forking is available to the first device after reversing the direction of the message flow between the first device and the control server and the callee has been contacted. Additionally, information flows between the first device and the second device through the control server as if the first device and the second device were directly connected.

Abstract: Providing non-voice capabilities relating to a phone call at a computing device includes receiving a request to begin a telephone call from a first telephone to a second telephone, wherein the requesting is performed using messaging between computing devices connected via a computer network, and wherein the messaging is part of a signaling phase dialog. The signaling phase dialog may be used in providing information associated with the identity of parties of the telephone call. Commencing a call phase dialog between the computing devices may be performed after the telephone call is established over the public switched telephone network. The call phase dialog may allow messages relating to the telephone call to be passed between the computing devices, at least while the telephone call is in progress. The dialogs and messaging may be performed using session initiation protocol (SIP) or another computer communication protocol.

Abstract: Independent telephony systems are integrated by using symmetric forking from both systems. Calls received by either system are forked to the other system. Thus, a call can be accepted by one of the systems, using its external interfaces, and presented to all devices in both systems. Each system is enabled to leverage internal call control advanced features to enhance overall user experience. Internally inserted parameters to call requests are used between the two systems for preventing endless loop of calls between the integrated systems.

Abstract: Systems, methods, and/or techniques ('tools') are described that sort speakers in a network-enabled conference. In some cases, this sorted list of speakers indicates which speaker is dominant. With this sorted list, a participant's communication device may provide context about the speakers. In some cases a participant's communication device has a display that presents real-time video of the speakers or other visual indicia, such as each or the most dominant speaker's name, picture, title, or location. These and other context about speakers may help participants better understand discussions in network-enabled conferences.
