As the leader of the Calling team within Cisco's IT Collaboration organization, I am driving the evolution of our global communication infrastructure by placing AI and AI Agents at the core of our operations. My team is dedicated to delivering seamless calling capabilities for all Cisco users, managing a complex ecosystem that includes Webex Calling, centralized SIP, VoIP, IP desk phones, and UCM.
We are transforming our operational model by leveraging AI-driven insights to enhance efficiency and proactively manage our environment. By integrating advanced observability tools like Splunk and ThousandEyes, we ensure maximum resiliency and performance across our global network. Beyond maintaining critical infrastructure-including global dial plan routing, site lifecycle management, and M&A integrations-we are committed to maintaining rigorous calling compliance. My leadership focus is on harnessing the power of AI to create a self-optimizing, highly resilient calling experience that empowers every Cisco employee.
