VoIP, the acronym for voice over Internet Protocol, is a way to directly transmit voice or other audio information via Internet Protocol (IP) networks, bypassing traditional telephone carrier networks. VoIP Technologies can be integrated with traditional PSTN infrastructures, devices, and protocols; based on developments in SIP/RTP technologies; and deployed upon wireless or fixed data networks. These technologies and protocols democratize communications in the workspace and in the home to allow anyone to engage in real-time communication regardless of their location. Dr. Lavian offers expert witness services in patent litigation cases, including expert testimony, expert witness reports and declarations, and patent analysis involving, VoIP, SIP, and streaming media.
VoIP is one of the fastest growing segments of the telecom industry. As VoIP technologies continue to grow, service providers are looking to implement turnkey solutions that include robust management interfaces and cloud-based functionality. Typically, the underlying transport and control protocols are SIP, RTP (RTP/UDP), MGCP, H.323 and its extension, WebRTC etc. Typically, VoIP projects include the integration of VoIP (Voice over IP) and streaming media with SIP (Session Initiation Protocol), Internet protocols (TCP/IP), and the traditional Public Switched Telephone Network (PSTN). VoIP systems are used as the backbone of unified communications systems.
VoIP technologies are usually deployed in business processes, especially e-commerce and business continuity. VoIP technologies are built on SIP (Session Initiation Protocol) over Real-time Transport Protocol (RTP), and other Internet protocols (TCP/IP). Some deployments include handset integration with text messaging capabilities over SMS or MMS, Instant Messaging (IM), and chat applications.
The “technology” is more appropriate than the “architecture”. The VoIP technologies concept indicates that an organization may use any media streaming technology, system, method or application that utilizes VoIP application layer protocols.
Dr. Lavian’s academic background and practical industry experience provide him with a profound depth and breadth of knowledge regarding VoIP, telecommunications, multimedia, streaming, and audio/video conferencing. He is highly experienced in different aspects of the relationships between Internet Protocols (TCP/IP), streaming applications, protocols, and services, and their underlying communications service architectures, designs, and implementations.
Dr. Lavian has extensive experience with network communications components which are part of the Internet architecture. He is intimately familiar with the Internet protocol suite (TCP/IP) and has proficiency in networking and communications technologies, including:
Dr. Lavian’s extensive experience with VoIP systems and protocols, audio/video conferencing, and streaming technologies, primarily as implemented through the TCP/IP protocol suite, gives him a keen understanding of the logic behind VoIP and streaming and their component application, transport, network, data link, and physical layers. He worked on multiple projects and solutions based on PBX, IVR systems, using Asterisk, SIP, and VoIP.
