Patent number: 9185051Abstract: A method for supporting communications includes establishing a packet-based audio communication link with a remote device and informing a local computing device of the audio communication link. A message requesting identification of enhanced media capabilities associated with the remote device is received from the local computing device and tunneled in the audio communication link to the remote device. A tunneled response in the audio communication link is received from the remote device and forwarded to the local computing device. The response identifies the enhanced media capabilities associated with the remote device.Type: GrantFiled: October 7, 2014Date of Patent: November 10, 2015Assignee: Cisco Technology, Inc.Inventors: James R. Tighe, Paul S. Hahn, Richard B. Platt, Rowan L. McFarland

Patent number: 7590231Abstract: A method for supporting communications involves establishing a communications conference that includes multiple conference participants that each provide an audio stream. Audio data packets in the audio streams are identified, and audio information from selected audio data packets is mixed to generate a conference audio stream that is communicated to the conference participants. Enhanced media packets in at least one of the audio streams are identified, and the enhanced media packets are communicated to selected conference participants.Type: GrantFiled: March 26, 2004Date of Patent: September 15, 2009Assignee: Cisco Technology, Inc.Inventors: James R.

Patent number: 7058067Abstract: Various aspects of an interactive multimedia system and associated methods. In general, the multimedia system employs central and peripheral hubs that function to provide services to a plurality of clients of a call manager server, or manager subsystem. The hubs and subsystem cooperate to serve requests originating in the plurality of clients. The client-server-client architecture allows for distributed processing and resource management. Redundant connections between the various network subsystems and hubs provide survivability. Each subsystem or hub is provided with the ability to initialize or recover from systemic errors, thereby distributing initialization and recovery. Certain of the distributed resources are capable of being managed from other subsystems, thereby allowing sharing of the resources. An open numbering plan allows efficient call treatment of dialed numbers. Call processing is sharable between multiple manager subsystems.Type: GrantFiled: September 27, 2001Date of Patent: June 6, 2006Assignee: Cisco Technology, Inc.Inventors: Robert David Corley, Richard A.

Patent number: 6757363Abstract: A system (10) includes a packet-switched network (12). A plurality of telephones (21-26) are each coupled to the network. A call manager server (31) is also coupled to the network, in order to interact with the telephones to implement telephony functions. Each of the telephones has the capability to act as an independent network client, by using Internet-compatible protocols to communicate directly with a resource server, without the participation or even the awareness of the call manager server. The resource server may be a local server (32) coupled directly to the network, or a remote server (66-68) coupled to the network through some other network, such as the Internet (52).Type: GrantFiled: May 31, 2000Date of Patent: June 29, 2004Assignee: Cisco Technology, Inc.Inventors: Richard B.

Patent number: 6115386Abstract: For use in a communications network capable of establishing a bonded call between first and second endpoints using at least two bonded communication channels, a subsystem for preserving a relative latency of the at least two bonded communication channels to allow the bonded call to be transferred to a third endpoint. The subsystem includes: (1) a buffer depth index detection circuit that detects learned values of buffer depth indices associated with the bonded call and stored at a first location and (2) a buffer depth index transmission circuit, coupled to the buffer depth index detection circuit, that transmits the learned values to a second location accessible by the third endpoint to allow the bonded call to be transferred to the third endpoint without requiring the third endpoint to relearn the values.Type: GrantFiled: March 11, 1997Date of Patent: September 5, 2000Assignee: Cisco Systems, Inc.Inventors: Robert T.
