Q&a: SIP Pioneer/Cisco Fellow Jumps Ship to Skype

My role is to direct our high-level system-level architectures across our products and work on our technology strategies and figure out what areas of investment we make, which technologies we bet on. That is a pretty broad mandate, especially for one guy, so I tend to focus on particular areas in projects. Much of my work has been focused in two areas, the Web and Skype For Business.

Wow, that is a big question. As with any technology that has added new products, Skype has seen a lot of change over the years. We've added mobile, we've invested in business via the Skype for SIP product and we've invested in video calling features, all of which have had an impact on our architecture. But we remain a peer-to-peer service for many of our core features and functionality and that works in concert with back-end services and infrastructure that support many of our paid products. So we are a hybrid technology today.
