Jonathan Rosenberg

I am CTO and Head of AI for Five9. There, I oversee the companies efforts around AI as well as guiding its overall technology directions. Prior to that, I was Vice President and Chief Technology Officer (CTO) for Collaboration at Cisco. There, I oversaw the architecture and technology direction of the next-gen Webex platform (formerly known as Cisco Spark). Prior to that, I was Chief Technology Strategist for Skype, and among other things, oversaw the integration of Skype into Facebook. Before that, I was a Cisco Fellow at Cisco Systems, having come to Cisco through the acquisition of dynamicsoft in 2004.

I've been a long time player in the IP communications industry. I'm most well known as the primary author of the Session Initiation Protocol (SIP), RFC 3261, inventor of SIMPLE (SIP for presence and IM) and ICE (Interactive Connectivity Establishment), the industry standard for NAT traversal. I'm the 5th most prolific author of Internet standards of all-time, and served in numerous leadership positions at the IETF.

I was awarded the Pulver VoN Pioneer award in June of 2000 for my contributions to the VoIP industry. In May 2002, Technology Review Magazine named me one of the TR100 - the 100 most innovative technologists in the world under the age of 35. I received my bachelors and masters degrees from M.I.T, and my P.h.D. at Columbia University under the guidance of Prof. Henning Schulzrinne.
