Thanks, John. Good afternoon, everyone. For those using slides today please join us on slide 4. Q2 was a tale of two very different trends that we saw on the quarter. First, on the positive side, we continue to stay stronger than ever market demand for CSG's industry leading solutions with a healthy growing sales pipeline that consistently leads to exciting big new sales wins each quarter. In the first half of the year our closed in one sales bookings, as measured by annual contract value grew more than 10% year-over-year when compared to our record setting 2021. On the back of these very good sales results we are reiterating our full year 2022 revenue and non-GAAP EPS guidance. On the less positive side, we felt some of the same macro inflationary challenges in Q2 that most global businesses are facing right now. A combination of increased labor and supply chain costs to staff and deliver some of the exciting new sales winds we announced in recent quarters were key drivers the erosion of our non-GAAP adjusted operating margin by over one percentage point coming in at 15.1% in Q2, and 15.7% for the first half, 2022. In order to quickly reverse the margin erosion we experienced this quarter into combat future macro pressures to CSG management team has already begun implementing a meaningful margin improvement initiative in Q2 across all aspects of our business to ensure we deliver both Q3 and Q4 at or even above the mid to upper end of our original target of 16.5% to 17% non-GAAP adjusted operating margin range. This margin improvement initiative will help us capitalize on the strong market demand and ensure we consistently operate at or above our historically strong profitability levels by relentlessly prioritizing every resource and every dollar of investment towards delivering on the significant new customer expansions and market share opportunities that we see in front of us. We anticipate that the timely actions we're taking to offset any inflationary headwinds will enable us to quickly capture millions of dollars in margin improvement across our business in Q3 and Q4, 2022 so we deliver at or above our target non-GAAP operating margin ranges in both quarters during the second half of the year. We believe that the winners of the future will be the companies who can most quickly adjust how they lead and grow in an inflationary business environment by embracing a scarcity mindset as a way to develop competitive advantages based on agility, creativity and innovation, and most importantly to us at CSG we believe that a disciplined growth mindset unleashed in a culture that puts our people and our customers first requires us to constantly improve how we prioritize and how we measure return on investments organically and inorganically to ensure that team CSG delivers fantastic results in both the short and longer terms. Turning to highlights for Q2 in the first half on slide five. We energized to see CSG business momentum continue, as demonstrated by the fact that ACV annual contract value sales bookings grew more than 10% year-over-year. The sales winds will contribute to good revenue growth in the second half of the year, and for years to come. As the sales winds generate more second half revenue, it will further benefit our non-GAAP adjusted operating margin in both Q3 and Q4. Financially, we grew both revenue and non-GAAP EPS by 3.6% year-over-year in the first half. We improved our industry leading market share in the cable industry. And won several fantastic new deals that I will talk about shortly. And we continue to get money back to our shareholders in the form of $55 million spent on share buybacks and dividends through the first half of the year. With the historically large sales wins we have consistently announced over the last three to four quarters come increased frontloaded expenses needed to deploy our cutting edge solutions to our new customers. These costs which primarily come in the form of hiring new employees in advance of large deployments, but that then smoothed out over the life of the project along with higher labor costs to staff these projects impacted our margins during the quarter. Additionally, we saw margin pressure from a couple other areas which Hai will share more detail on shortly. We remain extremely competent in our business and our ability to deliver strong CSG like financial results even in today's current business environment. As such, we are reaffirming our full year guidance of $1.07 billion to $1.11 billion and adjusted revenue guidance of 1 billion to $1.03 billion. We are adjusting slightly downward our full year 2022 adjusted operating margin percentage to a range of 16.2% to 16.7%. Given our lower margin in the first half of the year this means we expect to perform at or above the mid upper end of our guidance of 16.5% to 17% in both Q3 and Q4 as we start to see the benefits from our recent sales wins, customer conversions and meaningful margin improvement initiatives that began in Q2. We're modifying our adjusted EBITDA target to range from $220 million to $230 million. We are reiterating our non-GAAP EPS expectations of between $3.44 to $3.68 per share. We now expect our free cash flow for 2022 to range from $80 million to $90 million. The primary drivers for the decrease in our free cash flow guidance is related to higher tax obligations, primarily driven by section 174 of the 2017 tax cuts and job acts which deals with the amortization of R&D spending beginning in 2022. As a result of this CSG did not get the anticipated tax deduction benefit related to our R&D investments that we anticipated when we set the original 2022 full year guidance. Additionally, we are seeing significant timing differences in our crude employee related costs as planned in our original guidance targets in February, which Hai will discuss next. In addition to elevating every part of CSG and improving our quarterly financial results, we are committed to make a more lasting impact in the communities and the industries in which we operate across the wider environmental, social and governmental spectrum. While we still have much important work to do, we're very proud that leading organizations are beginning to recognize the meaningful commitment CSG has and will continue to make on the ESG and diversity, equity and inclusion fronts. Last quarter we mentioned that we received our first Prime ESG rating from institutional shareholder services, one of the leading ESG rating agencies in the world, and we continued our momentum on the ESG front by releasing our inaugural sustainability accounting standards board report, which you can find on the ESG section of the Investor Relations tab on our website. We are fully committed to providing investors, business partners and customers with access to reliable ESG data and making meaningful progress in this important area. From a technology and innovation perspective, earlier this year, we launched CSG exponents, our bold and innovative multi vertical market offering in the digital customer engagement space. We are delighted to announce that we have received multiple industry accolades from top analysts research firms like Forrester Wave, and Spark Matrix. Specifically, we are viewed as a leader in providing intelligent automation that delivers personalized, relevant and interactive experiences in real time across the entire customer lifecycle. Our best in class end to end suite of omni-channel solutions are helping great customer brands win big in the market by delivering extraordinary customer experiences and exciting new industry verticals. Turning to slide six, I will revisit the five strategic objectives that form the foundation of CSG's long term future success. These objectives have not changed and should be familiar to everyone who's followed our progress. CSG aspires to deliver long term organic revenue growth rate in the 2% to 6% range. We aim to add operating scale and expand our operating leverage by growing to at least $1.5 billion in revenue by year end 2025 with a stretch goal of $2 billion in revenue. We strive to be the number one SAS provider of choice for global communication service providers by providing the most value adding technology solutions, and by being easier to do business within our competitors. We plan to diversify our revenue even more as we expand in big faster growth industry verticals, with more direct sales and channel partner success in retail government financial services, healthcare technology and more. And finally, we will complement our accelerated organic growth with disciplined value enhancing M&A to turbocharge the value we bring our customers and our shareholders, while higher interest rates and higher cost of capital require us to be even more disciplined as we execute our M&A strategy the reduction in valuation multiples across many companies also means that we believe there will likely be attractive and accretive inorganic growth opportunities for us to execute against in the coming quarters and years. Moving to slide seven. You can see that we performed well in the first half of the year against these five strategic objectives. First on revenue growth. We reported $527 million in total first half revenue, resulting in 3.6% year-over-year growth, despite giving 3% to 5% discounts to two out of our three largest customers on the backs of the good renewals we signed late last year. For those who have known CSG for some time, think about how much stronger CSG is today. Even in the face of renewal discounts and macroeconomic headwinds, CSG grew revenue 3.6% and we consider this to be softer than expected results. We absolutely believe that we can and will deliver strong results in the quarters ahead. On the right hand side of slide seven we believe that the current economic environment benefits CSG's high recurring revenue, SAS business model and our strong healthy balance sheet creating attractive organic and inorganic market opportunities that are march to 2 billion and beyond. As a reminder by 2025, we aspire to gain scale in the markets where we compete to exceed $1.5 billion to $2 billion in annual revenue. We aspire to expand CSG's operating leverage and use our strong healthy balance sheet to deliver EPS growth that meets or exceeds revenue growth exactly as we did in Q2 even with the margin erosion faced in the quarter. In our base case, we aspire to exceed $1.5 billion in revenue which means even if we come up short against our stretch pace ambition CSG will still grow revenue by over 50% and add over $500 million in profitable recurring revenue by 2025. To reach the $2 billion stretch pace revenue aspiration, we will continue to allocate capital to its most value out of use and to eventually close bigger scale acquisitions that become even more transformational for CSG and for the industry. On its last point, I will continually reinforce a key message shared on almost every analyst and best recall. This management team is laser focused on creating shareholder value and growing profitable revenue, not building empires. We will remain disciplined and open to a wide range of strategic moves to unlock greater shareholder value. Turning to slide eight. We had good success in Q2 on our goal to become 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. In the cable market, we have long term guaranteed contracts to be the revenue management or monetization provider of choice for many of the largest U.S. cable companies, including Comcast and Charter the two largest and we are pleased that working hand in hand with Charter, the migration of subscribers from a competitor's billing system is continuing as expected, with approximately 75% of the new subscribers having been migrated to our platform, with the remaining subscribers expected to be migrated over the next nine months. And our success is not limited to North America. In the global telecom market we continue to grow with exciting new wins and contract extensions with leading telecom operators all around the world. In Q2 we signed one of our largest telecom wins in our history, with the leading telecom operator in Latin America and the Caribbean. In addition to being a fantastic new telco win this deal also highlights the power of our holistic offering for global CSPs. This deal includes our leading revenue management solutions CSG Encompass product catalog, and our CSG Xponent customer engagement offering is a powerful example of how we are truly helping the world's largest CSPs solve not only their back end BSS needs, but also their front end needs to ensure they deliver fantastic customer experiences. We look forward to sharing more details as we fully deploy our suite of products in 25 countries where this customer operates in the quarters ahead. In Sub Saharan Africa we also expanded our contract to enable the digital transformation of a leading telecom operator. Our solutions now serve over 90% of the entire Namibian mobile market. Turning to slide nine. Since 2017 CSG has grown revenue from exciting new industry verticals like retail, government, financial services and healthcare from 7% of total 2017 CSG revenue to over 24% of total revenue at year end 2021. And while this metric can vary a little bit from quarter to quarter, it is extremely encouraging to see approximately 26% of our Q2, and first half of the year 2022 revenue come from new industry verticals. Being a partner of choice for some of the biggest brands and higher growth industry verticals, where CSG helps them digitize and modernize their customer engagement and cloud payments continues to be a big game changer for us and our customers. During the quarter we landed a new digital engagement contract with AARP, a major U.S. nonprofit organization, which serves people ages 50 years and older through advocacy, information, insurance and other resources. We are thrilled that AARP will use CSG Xponent to improve the onboarding and support experience for its 38 million members by connecting channels and personalizing all communications specific to each member's individual needs. AARP chose CSG because of the open nature of our systems, AARP wanted to integrate our solutions in a broader ecosystem with solutions for the likes of Salesforce and Adobe. Our real time and omni-channel digital engagement offerings will enable AARP to enhance their digital engagement capabilities. Another great industry vertical win in Q2 was with a leader in the recreational camping industry, who specializes in selling recreational of vehicles, recreational auto parts and camping supplies. CSG Ascendance SAS platform was chosen to revolutionize their digital presence and help categorize, track and sell additional value added services such as trailer insurance, camping ground discounts, and camping equipment accessories. In the payments market last quarter, I highlighted how we returned to double digit revenue growth in the last two months of Q1 and I'm delighted that this momentum continued into Q2 as we delivered meaningful double digit revenue growth for the quarter. Our growth in the payments market is a testament to our industry leading recurring revenue SAS integrated payment platform. CSG Forte provides award winning payment platforms to over 90,000 active merchants and ISV partners who need ACH credit payment gateway and payment processing capabilities serving a wide range of recurring revenue industry verticals. As a leader in ACH processing we continue to add scale by signing ISV partners in fast growing industry verticals like property management and we're thrilled to be recognized for the second consecutive year by the Straw Hacker Group and their best of breed API assessment. This annual report ranks payment gateways for overall API experience and receiving this honor it reinforces that our team's dedication, work ethic and expertise are continuing to make a difference for our current and future customers. Looking ahead, we built an exciting sales pipeline in our payments business across multiple verticals that are contributing to our double digit revenue growth. Moving to the right hand side of slide nine. We continue to execute against our discipline value creation M&A playbook. May last year, we expanded our offering and the digital customer engagement market with the purchase of Kitewheel a SAS based recurring revenue company that supports real time interaction management, your omni-channel journey orchestration and analytics. This transaction form the foundation of our new CSG Xponent launch, our bold and innovative multi vertical market offering in the digital engagement space. And you've heard us talk about the acquisitions of Tango telecom, and Dgit last year they are included in our innovative CSG Encompass market offering. This quarter, we wanted to provide a little more color on how we think about M&A. In short, we look at several different factors when evaluating if an M&A target is a good strategic and value adding acquisition for us to move forward with. First we invest significant time and due diligence to ensure each acquisition as a strong strategic fit, financial fit and cultural fit; all combined with a healthy risk return profile. Secondly, we believe that several different types of M&A deals can create long term value for CSG our customers and our shareholders. Scale acquisitions are one type of M&A that can unlock shareholder value for the company. For us to move forward with a scale consolidation deal it must bring CSG sticky customer revenue, high cost synergies, and be quickly accretive with an attractive purchase price. New higher growth SAS capability acquisitions are a second type of deal we look forward to expand our CSG products suite. The three largest deals we did last year, Kitewheel, Tango telecom, and Dgit all fall into this category, which focus on CSG bringing greater value to the global customers we serve to expand our addressable market. New verticals and geographic market expansion is the third area where we look to acquire higher growth SAS companies that can expand how CSG helps great brands monetize and deliver exceptional customer experiences across a wide range of industry verticals. As I wrap up on slide 10. CSG is building meaningful momentum in elevating every part of our business that we fully expect will fuel our continued long term growth and transformation. We are making timely decisions that we believe will help us achieve both our short and long term objectives. As we close for us what was a very un-CSG like Q2 and build momentum for a much stronger second half of 2022 we asked ourselves two key questions to see where we could more quickly adjust to deliver the results we and our shareholders expect of CSG each and every quarter. Question one, are we seeing any softness in market demand for our industry leading solutions? Fortunately, the data in our ongoing sales wins prove that the answer to this question is an emphatic no. The market demand combined with our sales progress, and revenue growth, for all is strong and healthy as ever. Question two, are the softer Q2 adjusted non-GAAP operating margin and cash flow results in Q2 anomalies, are they the new normal for CSG? Fortunately for us in our investors, we believe that our softer Q2 operating margin was an anomaly that we can quickly correct with ongoing good revenue growth and a timely implementation of our meaningful margin improvement plan that we anticipate will enable us to deliver at or above the mid upper end of our prior 16.5% to 17% range. CSG is laser focused on delivering much better results in Q3, Q4, 2023 and beyond. We will continue to prioritize and invest in operating costs that deliver more customer value, accelerate our growth, ensure that we deliver strong operating profit and cash flow in the quarters and years ahead. As a result of all this, we hope you see the same thing that we do when we analyze our business. CSG's growth and innovation are clearly resonating in the market with existing and new customers all around the world, including in many exciting new industry verticals. Our strategic vision and agile execution position us well to adjust quickly, and whether the current macro inflationary environment and our customers continue to tell us that our people and our customer first culture are what differentiate us in our technology in the market. I couldn't be more grateful to CSG employees and leaders all around the world who every day turn market challenges into fantastic new wins on our march to build a bigger, faster growing and more purpose driven CSG. With that, I will turn it over to Hai to provide more detail on our Q2 results, and our full year outlook for fiscal year 2022.
