摘要： In one embodiment, a method comprises receiving through a telephony user interface from a user at the telephony user interface an indication of a first direction of a sound source along a first axis with respect to the user and a second direction of the sound source along a second axis with respect to the user. The first axis is substantially perpendicular to the second axis. The method further involves communicating the indication of the first direction and the second direction to enable audio communication of sound originating at the sound source to the user as if coming from the first direction and the second direction with respect to the user.

摘要： A conference adapter. In an illustrative embodiment, the conference adapter implements a method for interfacing one or more conference endpoints with one or more conference servers. The method includes registering an endpoint and a conference server to determine endpoint registration information associated with the endpoint and to determine conference-server registration information associated with the conference server. Next, the method includes receiving a connection from the endpoint and a connection from the conference server. Subsequently, the conference adapter establishes communications between the endpoint and the conference server as initiated by the endpoint and based on the endpoint registration information and the conference-server registration information. In a more specific embodiment, the method further includes receiving plural connections from conference servers of disparate types, and then selectively switching communications between the endpoint and a first conference server to communications between the endpoint and a second conference server. The method further includes selectively switching endpoints for a given conference session.

摘要： A Real-Time Protocol (RTP) source node of a network operates to send a first data packet of a first size to a destination node over a path of the network that includes a plurality of intermediate nodes, at least one of the intermediate nodes having a maximum transmission unit (MTU) size smaller than the first size such that fragmentation of the first data packet occurs. The destination node sends back to the source node a RTCP report that includes a number of fragments received and a largest minimum data packet size. In response, the source node sends subsequent data packets having a second size less than or equal to the largest data packet size of the fragments. It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.

摘要： In one embodiment, a system for conducting a conference session among a group of participants includes a server for establishing communication channels over a network connected with endpoint devices of the participants. The server operates to allocate initial resources on the network to conduct the conference session, the initial resources including the communication channels and at least one conferencing bridge. Code running on the server selects one or more different resources currently available during the conference session. The one or more different resources is selected to optimize a quality of service (QoS) criteria. Execution of the code causes the server to move the conference session to the one or more different resources responsive to a triggering event. It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure.

摘要： Techniques for storing voicemails in real-time in a caller's voicemail system when a voicemail is left in a callee's voicemail system are provided. A connection to the callee's voicemail system is detected during a call from the caller to the callee. When a voicemail is being left on the caller's voicemail system, a copy of the voicemail message is automatically forked to the caller's voicemail system. Thus, when a voicemail message is recorded on the callee's voicemail system, a copy of the voicemail message is also stored on the caller's voicemail system.

摘要： A system and method that provides a user with the ability to transmit confidential information to an IVR system in a secure manner includes invoking an interactive voice response (IVR) routine, the IVR routine determining each of the digits in the sequence by making successive queries and/or digit guesses. A user of the voice communication device need only make an affirmative response or a negative response to each query or digit quess. Once determined, each of the digits in the sequence is sent to the destination system. It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.

摘要： An intermediate network device performs service aware path selection. For example, the intermediate network device comprises a network interface that receives network traffic and a control unit that couples to the network interface. The control unit comprises a storage medium that stores a first set of cost factors for a first path from the intermediate network device to another intermediate network device. The first set of cost factors includes at least one optimization cost factor corresponding to intermediate optimization capabilities available to the intermediate network device that offset other cost factors of the first set. The storage medium also stores a second set of cost factors for a second path between the devices. The control unit selects either the first path or the second path over which to forward the network traffic based on the first and second sets of cost factors.
