Thanks, John. Hi, everyone. We appreciate you joining the call as we begin on Slide 4. CSG had a fantastic start to 2023, with excellent results in both Q2 and the first half. We posted 9.2% year-over-year revenue growth in the second quarter and 11.1% double-digit revenue growth for the first half of 2023, both coming from a 100% organic growth. Our performance over two quarters were the best first-half results we have posted in nearly two decades. Our Q2 non-GAAP adjusted operating margin was 16.2%, a nice step up from the 15.1% we reported in Q2 2022. Combining Q1 and Q2, it means Team CSG delivered 17.8% non-GAAP adjusted operating margin in the first half of 2023, which reinforces our commitment to maintain good operating discipline and expanding our operating leverage over time. CSG also grew bottom-line non-GAAP EPS in the first half to $1.84 per share, which represents 7.6% year-over-year EPS growth, even as we had to offset much higher interest costs so far in 2023. Based on our strong first half, we are pleased to raise our full-year 2023 guidance. We are raising our revenue guidance to range from $1.15 billion to $1.175 billion, which means we've raised the bottom end of our revenue guidance by $20 million and the top end by $5 million. The midpoint of the new guidance now reflects a 6.7% year-over-year organic growth in revenue. We are raising our full-year 2023 non-GAAP adjusted operating margin percentage to range from 16.75% to 17.1%, up from the prior 16.5% to 17% range. Hai will share more details on all our revised guidance momentarily. In addition to reporting fantastic growth in raising our full-year 2023 guidance, we're also announcing a new $100 million share repurchase program which will run through year end 2024. At the end of the day, our faster revenue growth was fueled by strong ongoing market demand for CSG's industry-leading SaaS products and good sales performance. CSG's sales pipeline is large and healthy as we win and wow big new customers in a wide variety of faster-growth industry verticals. I will share more details on several exciting Q2 customer wins in a few minutes. One question I often get from investors is whether we see any softening in market demand globally given higher interest rates and the risk of global economic slowdown in later 2023 or the first half of next year. While we continue to see good demand signals in customer buying behavior globally, I would share that almost all our customers are preparing for possible rainy day scenarios over the next 4 to 6 quarters. Based on what we see today, we continue to believe the CSG can grow organic revenue, consistent with our long-term 2% to 6% range as we strive to be at the midpoint or higher of this range in most quarters and years. So as CSG continues to focus on delivering sustained mid single-digit organic revenue growth or higher, like we posted in both Q1 and Q2 2023, we're also are continuing to take timely disciplined steps to keep our operating margin healthy and growing faster than revenue regardless of how global economic conditions unfold in the coming years. I would like to give a giant shout out for our fantastic Q2 results to CSG's nearly 6,000 global employees of which over 50% now live and work outside of the U.S. Having the majority of our employees residing outside the U.S. is not a coincidence. When I was announced as CSG's next CEO in Q3 2020, one thing was crystal clear to our Board of Directors and to our Executive Leadership team. For us to elevate into a faster growth more profitable, more relevant and more diversified SaaS technology leader, CSG needed to become a more talent rich, globally diverse company. A fantastic example of how our global team is executing on this is CSG India being named one of the top 100 Best Companies to work for in India in 2023 which we publicly announced in June. The success and momentum we're seeing in the first half results are 100% attributable to the dedication and talent and innovation of CSGers all around the globe. We will continue investing in our people, our products and our customers to grow revenue faster while we simultaneously expand our operating margins as we had meaningful size and scale in the years ahead with excellent operating discipline. Turning to Slide 5, I will reiterate the 4 strategic objectives that will help CSG create more shareholder value and allow followers of our story to track our progress. As I just shared CSG aspires to deliver long-term organic revenue growth in the 2% to 6% range, striving to consistently be at or above the midpoint of this range. That is why we're so pleased to see the midpoint of our revised 2023 revenue guidance sitting above the top end of this range at approximately 6.7%. We aimed at operating scale and expand our operating leverage by growing revenue to $1.5 billion by year end 2025 with bottom line growing as fast or faster than top line growth. This scale will come from a combination of good organic revenue and sales growth combined with disciplined inorganic moves. Further, we strive to be the number one SaaS provider of choice for global communication service providers, by providing the most value adding technology platforms and by being easier to do business with than our competitors. And finally, we plan to diversify revenue even more as we win big and faster growth industry verticals like retail, government, financial services, healthcare technology and more. Moving to slide 6, you can see, we delivered against all four objectives with our excellent start in the first half of 2023. On strategic revenue growth, we reported $585 million of revenue for the first half of 2023, resulting in a 11.1% year-over-year growth. Our best first half results in nearly 20 years. On the right-hand side of Slide 6, we believe that CSG's high recurring revenue SaaS business model and our strong healthy balance sheet, make us an attractive investment. By 2025, we aspire to gain scale in the markets where we compete and generate $1.5 billion in annual revenue, which implies that CSG will have added over $0.5 billion in profitable recurring revenue from 2020 to 2025. Over the medium to long-term, we aspire to expand CSG's operating leverage and use our strong balance sheet to deliver non-GAAP EPS growth that meets or exceeds revenue growth. On this last point, I will continually reinforce a key principle for the CSG Board of Directors and management team. Investors can be assured that team CSG is laser-focused on creating shareholder value and earning the right to grow profitable revenue faster, not adding empty revenue calories. We will maintain a disciplined high return on invested capital mindset as we explore a wide range of strategic moves to create more shareholder value. Turning to Slide 7, we had good successes in the first half of the year on our goal to be the number one technology provider of choice for communication service providers globally. And our continued success with both North American and global CSPs proved that we are executing well against this strategic priority. It is great to see that CSG grew revenue at our two largest North American broadband cable customers by approximately 7% year-over-year in Q2 2023. This result was partially driven by the migration of subscribers at charter from a competitor's billing system over the last 12 months, but we also saw good growth coming from business expansion in other areas with our two largest customers as we help them solve many of their most important business objectives. With respect to new logo wins, we recently announced a great new deal with ATN International, a leading provider of digital infrastructure and communication services. Team CSG will modernize their networks with our mediation roaming settlement products. This will enable ATN to automate mediation and wholesale settlement workflows and access real-time performance data to better align resources and to more quickly react to changing business needs. And we continue to win more business and the wireless telecom market. During the quarter, we announced a fantastic new deal with PLDT, the Philippines largest fully integrated wireless operator. PLDT is expanding its two-decade partnership with CSG as it embraces the power of the cloud to bring its wireless business into the future and transform its customer experience, particularly for its enterprise unit. This large scale revenue management and BSS transformation, empowers PLDT Enterprise with a cloud-based unified billing and revenue management solution that enables streamline processes across its business segments, minimizes cost and shortens time to market. Plus, this is the latest example of us serving our customers in an environment of their choice, this one and Amazon Web Services cloud-based solution. Also a few weeks ago, we announced the completion of our digital BSS transformation project with Airtel Africa. A leading telecommunications and mobile money service provider with almost $140 million wireless subscribers across 14 countries in Africa. With CSG's unified revenue management solution, Airtel Africa is prime to streamline processes across its business minimize cost and shorten time to market while delivering digital experiences to drive customer loyalty and sustainable business growth. Turning to Slide 8. Since 2017, we have diversified our revenue coming from exciting new industry verticals from 7% of total 2017 CSG revenue to 28% of our first half 2023 revenue. A fantastic accomplishment in a relatively short amount of time. We are a partner of choice for big brands in higher growth industry verticals where we will help our customers digitize and modernize their customer experience and provide them with cutting-edge integrated payment solutions. And during the first half of 2023, both solutions delivered good double-digit organic revenue growth and continued to be game changers for CSG and our customers. During the second quarter, we expanded our customer experience business with NRC Health, one of the nation's largest healthcare performance improvement firms, supporting more than 7,000 organizations. We are enabling NRC to execute a digital multi-channel communication strategy in a streamlined, effective and scalable manner. Another nice Q2 win was a contract expansion with one of the world's leading technology firms. We are deploying our AI-powered digital CX solutions to provide their customers self-service capabilities in the voice channel. These solutions will help reduce the number of contact center calls, lower the number of agent-to-agent phone transfers and limit the number of repeat customer call center contacts. This is an excellent example of how CSG's AI-driven digital CX SaaS platforms, how big exciting brands improved customer experience and save operating costs. Also in Q2, we landed a good contract with a bundled utility service provider for municipal and private utilities to support various customer engagement initiatives. This deal expands our footprint in the utility industry and is another example of how our customer experience suite of products is finding use cases across multiple industry verticals. In the payments market, our continued double-digit revenue growth is a testament to our industry-leading SaaS integrated payments platform. We now provide award-winning payment solutions to approximately 106,000 active merchants and ISV partners, who need ACH, credit card, payment gateway and payment processing capabilities serving a wide range of recurring revenue industry verticals. In July, we were recognized by the strong hacker group, as having the best payment API set in their Annual Best of Breed Award showcase. As a leader in ACH processing, we continue to add scale by signing ISV partners in faster growing industry verticals like property management. I will wrap up on Slide 9 before turning it over to Hai. Fiscal year 2023 is off to a fantastic start. We grew first half organic revenue double digits on a year-over-year basis. We continue to win fantastic new customer logos, quarter in quarter out in addition to growing revenue nicely at our two largest customers. We continue to diversify our business with over 28% of revenue coming from big faster growing industry verticals like healthcare, financial services, retail, tech and government. And we continue to demonstrate our commitment to run our business more efficiently with first half non-GAAP adjusted operating margins in the high 17% range. So our message to our three key stakeholders are clear. To our employees, CSG's best days and biggest breakthroughs are still ahead of us. We will keep dreaming big and demanding even more from our collective global talent as we do whatever it takes to turn our giant dreams into reality. To our customers, CSG is here for you. We are dedicated to being easier to do business with than any of our competitors while solving your toughest business and technology-related challenges. We thank you for your continued trust in CSG. To our shareholders, CSG's transformation is just getting started. Faster recurring revenue growth, improved operating leverage and exciting industry vertical diversification but what this management team and our Board of Directors will hold ourselves accountable to. And we will do it with a high integrity, focused execution and good governance that you've always come to expect from CSG. With that, I will turn it over to Hai to provide more detail on our Q2 and first half results as well as our revised guidance targets for 2023.
