Developed embedded object oriented C++ for Avaya’s Media Gateway family of products. Authored requirements and software architecture for several features. Designed and developed automated regression tests (Visual C++ and Perl) for each feature. Several features were proven defect free by system test. Sample features:
• H.248 protocol and associated transaction management for the media gateway and the call server
• Survivable call server features such as Dial Plan, ISDN and H323
• Designed and implemented a proprietary protocol modeled off Transport Layer Security
• Hot-patch tool, capable of replacing portions of software while the system is running
• Voice blade gateway, compatible with Juniper routers
• Gateway configuration via SNMP and Command Line Interface
Improved significantly team productivity by developing a call server simulator. Developed web tools using Ajax and MySQL to accelerate administration of defects and release content.
