Colleagues describe him as "After an extensive search VBrick hired Dan to provide a key component of our Video Conferencing Gateway. The goal of the project was to provide an interface between the video conferencing/SIP ecosystem and the video streaming ecosystem. Although we had expertise in the streaming protocols, we lacked any extensive knowledge of the SIP/Video Conferencing protocols. Dan worked closely with our engineering team in all phases of the project from design through deployment and implemented an elegant and complete solution. I was very impressed with Dan's overall knowledge of the subtleties of the SIP protocols. Dan and his team were always willing to make the effort to assure very high quality and robustness of the solution. Since we were constantly encountering different vendor's equipment each with their individual subtleties in various customer trials, Dan's willingness to be responsive to our business needs at short notice was important to our relationship. I would highly recommend Dan for his expertise, responsiveness, and commitment to quality." and "As part of our product line upgrade, Our company (3Com) wanted to provide SIP functionality in our portfolio of VoIP gateway and phone endpoints.
