Consulting Engineer

  • Developed a recording application on server with SIP call control for recording using a Radvision SIP stack with C wrappers and C recording control on Windows Server 2012. Implemented the asynchronous Cisco port driven recordings.Evaluated various approaches with working prototypes and design analysis documents.
  • Developed assembly of media call segment, merging of media streams for customer and agent sides, and transcoding of .wav files into wma files on a Media Server. Compared performance of codec types.
  • Developed functionality for controlling call recording in VB.NET by correlating asynchronous media recording ports with TAPI Cisco device specific messages in simple calls, holds, transfers, and conference interactions. Used VB.NET to keep track of all call segment files with details of Cisco Updates during transfers and conferences. Microsoft SQL servers for storage and retrieval of call recording records with C for SQL queries.
  • Implemented a number of load balancing and system availability approaches SRV records, Cisco routing patterns and failover for reducing down time on recording server failures. Designed the system to work with and without CTI or monitoring server.Implemented a quick fully functional Radvision based SIP proxy with load balancing across recording servers. Constructed a load test environment in a virtualized environment with over 300 ports, SIP Hammer load generator, SIP trunks to Cisco and Hyper-V VM's for running client IP Communicator and CTIOS Agent applications.

Senior Architect

  • Led roadmap for internally developed SIP stack and VoIP phone clients. Targeted for video telephony and Push-to-talk devices in public safety. Established collaborative environment for sharing technologies with product groups. Created VoIP solution proposals for opportunities in public safety and in 4G Networks.
  • Developed proposal and secured funding from Corp VP for a 4G Location project. Project resulted in location solution trial for a major US carrier. Enabled WiMAX sales into targeted countries.
  • Engaged and influenced research team to develop TDOA location algorithms for WiMAX , collaborated with product management team for chipset suppliers, solicited help from Alpha networks for demo venue. Assured early demos of product by leading Windows C application development with GoogleEarth and MySQL. Solution is about 1/20th the cost of other competing location products.
  • Led the development of a telephone interconnect product shipping worldwide with projected sales of 20- 30M.
  • Included all aspects of the project from finding opportunity to eliciting software requirements, flow of messages and functionality, reverse engineering undocumented elements, integrating components into system, overseeing software development, system testing, and customer acceptance.
  • Analyzed quality concerns with video streaming over LTE at various interference levels and evaluated algorithms to adopt video resolution - leading to improved video quality. Helped with the analysis of QoS over WiMAX between BE and eRTPS on the MOS scores for VoIP calls leading to unexpected results and provided insight into deep packet inspection on the LTE network side.
  • Constructed a demo environment of location - prototyped MS Communicator via OCS and WCA.
