Abstract: A system for using one or more via sites to manage network bandwidth, according to one embodiment of the present invention comprises a first call manager at a source site receiving an offer message to connect a call. The offer message includes an endpoint media settings list. The first call manager determines a first filtered media preferences list based on a source media settings list and the endpoint media settings list. The first call manager and transmits an invite message to a second call manager at a first via site. The invite message includes the first filtered media preferences list. The first call manager receives from the second call manager a call settings list that includes a description of the call settings negotiated between the source site, the first via site and a destination site.

Abstract: A method for providing conference information to attendees of a conference call near real time using a plurality of conference bridges includes receiving the conference information at a first conference bridge. The conference information is generated in response to input from a participant in the conference call using a first device. The method also includes providing the conference information from the first conference bridge to a first group of attendees. The method also includes providing the conference information from the first conference bridge to a second conference bridge separate from the first conference bridge, and providing the conference information from the second conference bridge to a second group of attendees.

Abstract: A method for joining a teleconference includes receiving a schedule for the teleconference at a conferencing system. The schedule may include a start time for the teleconference and one or more conference rooms for attendees to use during the teleconference. A first message is sent from the conferencing system to the at least one communication device. The first message indicates to the at least one communication device to provide a user notification associated with the teleconference. A second message is received at the conferencing system. The second message is sent in response to an action by an attendee of the teleconference. The second message indicates to the conferencing system to initiate the teleconference with the at least one communication device or to join the at least one communication device to the teleconference.

Abstract: A method for providing conference information to attendees of a conference call near real time using a plurality of conference bridges includes receiving the conference information at a first conference bridge. The conference information may include at least one of video or web data generated in response to input from a participant in the conference call using a first device. The method also includes providing the conference information from the first conference bridge to a first group of attendees. The method also includes providing the conference information from the first conference bridge to a second conference bridge separate from the first conference bridge, and providing the conference information from the second conference bridge to a second group of attendees.

Abstract: Routing an incoming call for an IP phone system is disclosed. A location data for a mobile device is received. A way point based at least in part on the location data is determined. A state for a user of the IP phone system is determined based at least in part on the way point. An incoming call is routed to the IP phone system based at least in part on the state.

Abstract: A system for managing network bandwidth, according to one embodiment of the present invention comprises a configuration storage module and a call manager. The configuration storage module includes a supported codecs storage, codec lists, administrator settings storage and reservation storage list. The call manager includes an extension module, trunk module, location service engine, settings manager, bandwidth manager and media stream manager. The call manager receives an offer message for a call having one or more media types. The call manager uses information included in the offer message, along with information stored in the configuration storage module, to negotiate a call settings list with one or more other sites for connecting the call, and thereby manage bandwidth for the call.
