Good afternoon and thank you for joining our fourth quarter earnings conference call. I would like to start this call with a warm welcome to our newest board member, Secretary Arne Duncan. Arne is a former United States Secretary of Education. Prior to his federal government service, Arne was CEO of Chicago Public Schools for eight years, and he is currently a senior fellow at the University of Chicago Harris School of Public Policy. Welcome, Arne. Now to RingCentral. 2020 was a transformational year. The global pandemic is fundamentally changing how businesses operate. With a vaccine now being distributed, many businesses are preparing for a hybrid work environment. They are planning for some workers in the office and some at home for the foreseeable future. As companies adapt to this new work from anywhere norm, digital transformation of business communications will become more critical. Enabling this transformation are cloud-based communications solutions. This is essential to enabling employees to productively engage with customers, partners, and peers from anywhere, on any device, and in any mode. According to Gartner, by 2024, 74% of the new unified communications licenses purchased by organizations will be cloud-based, up from 48% in 2019. Businesses are increasingly turning to RingCentral as a trusted partner in their transition to a cloud-based communications platform. This growing customer demand is evident in our strong and standout Q4 results. Total revenue grew 32% year-over-year to $335 million, an acceleration of two points sequentially. RingCentral Office ARR grew 39% year-over-year to $1.2 billion, an acceleration of three points sequentially. We delivered a record number of $1 million TCV wins, up over 50% sequentially and we had strong contributions from our key partners led by Avaya, AT&T and Atos. As we look to 2021 and beyond, we are increasingly confident in the size of the opportunity and market receptivity to our differentiated Message Video Phone or MVP, as we call it, and cloud contact center solutions. These together enable us to address the full range of business communications needs for most enterprises worldwide. And now with the recent addition of RingCentral Glip, our free, unlimited Smart Video Meeting solution, we can help even more businesses or their individual departments to communicate in any mode, on any device, from anywhere. Please visit glip.com to experience it for yourself. Our leading UCaaS solution, RingCentral Office, is an enterprise proven, carrier grade, global, trusted Message Video Phone or MVP solution. It offers a seamlessly integrated multi-mode user experience, five nines reliability, world class global coverage, and an open platform, all of which we believe are important competitive differentiators. We are also proud to once again be recognized as a leader in the latest Gartner Magic Quadrant for Unified Communications as a Service, worldwide report for the sixth year in a row. In addition, RingCentral ranked highest in all five use cases of the 2020 Gartner Critical Capabilities for Unified Communications as a Service worldwide, report. Leveraging all the strengths of our industry leading cloud PBX platform, we have recently added RingCentral Video, a new core component of our MVP solution. RingCentral Video is built on the modern WebRTC industry standard framework with numerous proprietary enhancements. We continue to innovate here at a rapid pace. Some of the recent enhancements include virtual backgrounds, closed captions, third-party virtual camera support, and waiting rooms. Earlier this month, we introduced RingCentral Embeddable for RingCentral Video enabling developers to quickly embed video into business applications. And in Q4, we acquired certain technology assets of a company called DeepAffects, a pioneer in AI-powered conversational intelligence. DeepAffects will enable us to provide RingCentral Video with new capabilities such as emotional sentiment recognition and multi-speaker identification. To help businesses transition to cloud communications solutions, we recently introduced RingCentral Glip, our free Smart Video Meeting solution available through our glip.com website. Glip provides unlimited RingCentral Video meetings seamlessly integrated with team messaging capabilities, all at no cost. This smart meeting solution provides users with a persistent platform for communications before, during and after meetings. This is an important differentiator from other single mode video solutions available today. And of course all of this with RingCentral's carrier-grade quality, security, reliability and global footprint. Complementing our UCaaS solutions is the RingCentral CCaaS product portfolio. We are seeing strong cloud adoption trends with many customers choosing integrated UCaaS and CCaaS from a single leading provider. Contact center was included in over 60% of our $1 million TCV wins in Q4, including multiple wins for our native RingCentral Engage cloud contact center platform. We're particularly proud of a recent 2,000 user win that combines RingCentral Office with RingCentral Engage. This major NGO customer will leverage the full power of RingCentral to help people displaced by COVID-19 find new employment. In conclusion, we have a strong, well-differentiated portfolio of industry-leading cloud communications solutions. And over the past several years, we've focused on finding new, innovative ways to efficiently bring these solutions to global markets. On that note, I'd like to extend my warm welcome to Vodafone Business as our newest key partner. Vodafone is the largest mobile and fixed network operator in Europe. RingCentral will be the lead UCaaS offer for Vodafone Business' installed base of over 30 million customers. Vodafone Business will also offer RingCentral's CCaaS customer engagement solutions. RingCentral believes in winning through partnerships. Over the past several years, we have established a unique go-to-market ecosystem of direct, channel, and strategic partnerships. RingCentral is a lead UCaaS provider for Avaya, Atos, Alcatel-Lucent Enterprise, AT&T, BT, Telus and now Vodafone Business. This gives us preferred access to over 200 million potential users worldwide. We are humbled and grateful to find ourselves in this unique position and we are committed to driving a pace of rapid innovation and GTM expansion to continue delivering world class cloud communications solutions for years to come. With that, I will now turn the call over to our President and Chief Operating Officer, Anand Eswaran, for additional details on our progress and some recent achievements.
