Confidential, Framingham, MA

Senior Engineer

Responsibilities:

Created and updated a middleware on top of Natural Access to support conferencing between ISDN PRI & IP based calls. The IP calls were controlled using H.323 & SIP call control, and consisted of the following codecs: g.711, g.729a, g.723, g.726. The IP calls supported both IPv4 & IPv6 protocols. This project required working directly with the customer to partition the modifications over several phases. The middleware runs on Intel/Sparc Solaris 7 & 8 (32-bit and 64-bit mode).
Created test application ipv6nailed. This application used an AG2000 and a CG6000 board to connect up to 8 phones to a mixture of ISDN controlled calls or IP calls (IPv4 & IPv6).
Helped port the Host Media Platform (HMP) runtime to the Linux Red Had 9.0 OS.
Developed demonstration utility startip. This multi-threaded application assigns IPv4 or IPv6 addresses and ports to either a CG Board (6000/6500) or a HMP system.
Ported the Unix based hotswap service and drivers to QNX Neutrino.
Worked with Confidential to resolve a fax problem over the Ericsson cellular network. Validated V.29 protocol and signal level attenuation using Fax Probe.
