A Conversation with Cullen Jennings and Doug Wadkins

ABSTRACT

In our interview this month, Cisco Systems’ Cullen Jennings offers this call to arms for SIP (Session Initiation Protocol): “The vendors need to get on with implementing the standards that are made, and the standards guys need to hurry up and finish their standards.” And he would know. Jennings has spent his career both helping define IP telephony standards and developing products based on them. As a Distinguished Engineer in Cisco’s Voice Technology Group, Jennings’s current work focuses on VoIP, conferencing, security, and firewall and NAT traversal. His primary responsibility is setting the direction of the technology that will make up the next generation of Cisco’s voice products, especially those concerned with conferencing, presence, and rich media systems.
