Telephony

COMPUTER TELEPHONY BOARD DIAGNOSTICS — Developed a CORBA client server interface on a Linux platform for a computer telephony board diagnostic tool. The CORBA clients were written in JAVA, and the servers in C++, providing a distributed interface between a JAVA GUI and the legacy background software written in C.

INTEGRATED VOICE RESPONSE SYSTEM — Developed, enhanced, maintained, and supported an Integrated Voice Response system, including applications which produced Visa Network transactions for credit card authorization and end of day transaction clearing.

TELEPHONY SWITCH RESOURCE MANANAGEMENT SYSTEM — Developed a Java-based systems management console for monitoring telephony switch resource management via a Web browser over a corporate intranet. The JAVA applets interfaced with an SNMP management station via TCP/IP, allowing for the display and modification of alarm and status data.

ISDN TELEPHONY CLIENT/SERVER SWITCHING SYSTEM — Wrote software, system integration and system acceptance test plans for an ISDN telephony client/server switching system. Designed tests, wrote a complete suite of test procedures, and developed a database for all test cases, including TCP/IP LAN and Frame Relay WAN communications tests for the fault-tolerant UNIX platform. Developed prototype GUIs and test-support applications for UNIX-based systems using C/C++, Bourne shell and other UNIX utilities.

SS7 TEST PLANS AND PROCEDURES — Designed and executed tests for a satellite-based digital telephony system. The system utilizes a Signaling System 7 (SS7) network that supports a mixture of voice and data applications. The network control system software runs on Sun OS (Unix) and VAX/VMS platforms.
