A method is described and in one embodiment includes receiving a request to participate in a web-based conferencing session using an IP phone, wherein the web-based conferencing session is hosted by a server; establishing an encrypted connection to the server; requesting network routing information for the IP phone from a call manager; receiving from the call manager the requested routing information; and establishing a connection with the IP phone using the received routing information. The method may further include embodiments in which the request to participate in the web-based conferencing session is initiated by a user via a client application executing on a computer device and in which the encrypted connection is established over an Internet.

Techniques for implementing telephone call back for a multimedia conferencing platform

A scalable media conferencing system minimizes delay while maintaining a consistent session across all of the distributed media servers handling the conference session. Each of the media servers sends a list of the local top streams and their importance. A global list of top streams is created and disseminated to all of the media servers. Each of the media servers then forwards any local stream that is on the list of global top streams to all of the other media servers. Once a media server receives all of the streams on the list of global top streams, it locally mixes the streams together and outputs the mixed stream to the endpoints that are locally connected to that media server.

Distributed audio mixing and forwarding

In one embodiment, a method includes receiving requests to join a conference from a plurality of user devices proximate a first endpoint. The requests include a username. The method also includes receiving an audio signal for the conference from the first endpoint. The first endpoint is operable to capture audio proximate the first endpoint. The method also includes transmitting the audio signal to a second endpoint, remote from the first endpoint. The method also includes identifying, by a processor, an active speaker proximate the first endpoint based on information received from the plurality of user devices.

Active speaker indicator for conference participants

In one embodiment, a method includes capturing samples of sound associated with an environment, and processing the samples of sound to determine whether the samples of sound likely include voice activity. The samples of sound are captured while a microphone is muted. When it is determined that the samples of sound likely include the voice activity, the method also includes providing a first notification arranged to indicate that voice activity is detected and that the microphone is muted.

Method and apparatus for providing an intelligent mute status reminder for an active speaker in a conference

A method, a system and computer readable storage media facilitate receiving a data stream from a host media server that is outside of a network, designating a multicasting source within the network to receive the data stream from the host media server, and multicasting the data stream from the multicasting source to a plurality of client devices within the network.

Client assisted multicasting for audio and video streams

In one embodiment, a participant device joins a collaboration session among a plurality of participant devices. The content shared within the collaboration session includes lower-priority data and higher-priority data. An initial available bandwidth for use with the collaboration session is determined. Based on the initial available bandwidth and an expected second bandwidth for higher-priority data shared within the collaboration session, a first bandwidth is allocated for lower-priority data shared within the collaboration session. During the collaboration session, an actual second bandwidth for the higher-priority data shared within the collaboration session is monitored. The expected second bandwidth is compared to the monitored actual second bandwidth, and a bandwidth variant is determined. Based on the determined bandwidth variant, the first bandwidth allocated for the lower-priority data shared within the collaboration session is adjusted to increase the bandwidth allocated for the lower-priority data.

Methods and apparatuses for adjusting bandwidth allocation during a collaboration session

In one embodiment, the systems and methods determine an initial bandwidth at a client device; allocate an allocated bandwidth to the client device between a first server and a second server; monitor the allocated bandwidth; and adjust the allocated bandwidth based on a target bandwidth from the first server to the client.
