Senior engineer on Converged Services Framework (CSF) - carrier-grade platform for deploying value-added voice and data services. Primarily responsible for developing telephony-based features and services, platform architecture, troubleshooting, and prototyping new technologies. Also oversaw all aspects of telephony hardware, VoIP gateways. SME on telephony protocols such as SIP, SS7. As uReach was a small start-up, position also required ability to design/develop/troubleshoot all areas of the platform.Highlights:- Led effort to design and implement CSF VoIP infrastructure. Led to CSF selection by several large North American telephone carriers. Developed RTP mechanisms for both voice and FAX (T.38), converted PSTN-based telephony applications to SIP/RTP, adapted open-source SIP proxy for call distribution and fail-over.- Developed generalized call control protocol, allowing seamless support of VoIP/ISDN/SS7/CAS signaling in single CSF software distribution.- Designed and implemented highly available SS7 platform used in deployments requiring ISUP call control and/or TCAP-based transaction services. Key to winning business of several carriers requiring SS7 signaling. Current SS7 deployments handle 1M+ calls daily. SS7 implementation also required adapting CSF telephony applications to use SS7 signaling, development of high-availability monitoring and control software.- Led engineering and development effort to adapt CSF to use legacy SMDI signaling and CAS trunk protocols. Enabled major US carrier to replace multiple legacy voice mail systems in NY/NE regions with single CSF platform. Integrated VoIP gateways into CSF.
