As an R&D Engineer I have worked on:• Agile Methodology model for the WebRTC Gateway Project.• Functional,Interoperability and feature testing of WebRTC(Web Real Time Communication) and VOIP Gateways• The Application Client-Server model for the WebRTC Gateways.• Deployed the application gateways on various Linux distributed platforms.• Scripted design scenarios for feature automation.• Performed Selenium Automation using Java and java scripting for the application APIs for the WebRTC Gateway.• Regressed features specific to Sonus Products.• Debugged of the failure scenarios and customer interaction.These were the specific responsibilities that I undertook during my tenure in Sonus: • Was responsible for the analysis of the product interaction with SBC(Session Border Controller) Media Gateway.• Devised and analysed call flow scenarios using ICE( ICE_LITE and FULL_ICE) variants for WebRTC and media Gateways.• Configured and scripted feature functionality of DTLS as a security being relayed or terminated on the Session Border Controller with the WebRTC Gateway.• Deployed the WRTC Gateway on OpenStack, VMWare and other cloud platforms.• Tested routing and feature capabilities of the product with the Media Gateway using policy Routing Engines with Sonus Policy Server (Policy Server)• Analysed the trans-coding scenarios of WebRTC with the Endpoints using the media Gateway using Audio Codecs(G711,G729,OPUS) and Video Codecs(VP8) .• Scripted test case specific scenarios in Perl.• Computed Message Manipulation techniques to manipulate the SDP headers when reaches the SBC from the Browser Client.• Configured of the EMS(Element Management System) for the Gateway using REST Interface and configuration of the media Gateway for the interaction with SIP and PSTN endpoints.• Drafted feature execution plans and reviews and handled customer issues.

• Worked as an intern in the team which streamlined on the design and commissioning for the installation and setup of the EPABX (Electronic Private Automatic Branch Exchange) corresponding to the Siemens Hi-Path 3000 series.• Worked on the hardware deployment for the EPABX equipment which involved deployment of the PRI cards with the system capability to handle both the packet switched(LAN/WAN) and line switched(ISDN) environments and firmware upgradation.• Assisted in the commissioning of the different Siemens IP and Non-IP based Switches like HiPath 1100, HiPath 3000, HiPath 4000 and their legacy systems at the client’s site.
