Contributed actively to system architecture design specifications of the Vo-IP/Multimedia Communication System “HiPath 5000” and assumed the technical lead and architectural responsibility for two major software components: | |||
Siemens Network API (SNAPI) | |||
Designed, managed and implemented network protocols, Telephony APIs (TAPI, JTAPI, CSTA) and Computer Telephony Integration (CTI) interfaces using C, C++, JNI and JAVA. | |||
Supplementary Services Component (SsC) | |||
Designed, managed and implemented telephony signaling protocols (H.450, QoS, H.235 Security) including ASN.1 Compilation, En/De-Coding using C++ Object Oriented Programming/Design. | |||
Participated in the design and development of a SIP - H323 gateway prototype. | |||
18.10.99 - 14.07.00 | Software Engineer at Siemens Business Communication Systems, Inc. in Santa Clara | ||
Designed and developed components for SIEMENS telecommunication products based on H.323 Standards. One specific area was the design and implementation of Supplementary Services as defined by the H.450 ITU Standard (implementing existing features and proposing new features for standardization). | |||
Design and analysis using C++ Object Orientated techniques. | |||
Worked with ASN.1, both at the syntax and implementation level. | |||
Submitted new Supplementary Features to the ITU standards body. | |||

Supplementary Servives for IP Multimedia Communication | |||
Review project documentation, vendor documentation, applicable standards documents (e.g. H.323, H.450.x etc). Acquire information via Internet and library researches. | |||
Develop ASN.1 syntax for the primitives exchanged between the Message-Waiting-Indication signaling entities and an application. | |||
Write a utility in C to print out the syntax tree of an ASN.1 message. | |||
Write signaling entities for Message Waiting Indication in PDL (Protocol Description Language). | |||
Develop a H450 Test API residing in the H.323 stack to exports the functionality of the signaling entities to the application and to enable sending and receiving messages to and from the signaling entities. | |||
Write a test application in C using the H450 Test API to test the proper functionality of the Message-Waiting-Indication signaling entities. | |||
Develop a general interface mechanism to send and receive primitives in a tree-structured text string. | |||
Give presentations and organize meetings to share acquired knowledge within the development team. | |||
Identification and submission of any patent ideas or concepts. | |||
