 ### Background blur and custom backgrounds (Public Preview)
 Background blur gives users a way to remove visual distractions behind a participant so that callers can engage in a conversation without disruptive activity or confidential information appearing in the background. This feature is especially useful in a context such as telehealth, where a provider or patient might want to obscure their surroundings to protect sensitive information. Background blur can be applied across all virtual appointment scenarios to protect user privacy, including telebanking and virtual hearings. In addition to enhanced confidentiality, the custom backgrounds capability allows for more creativity of expression, allowing users to upload custom backgrounds to host a more fun, personalized calling experience. This feature is currently available on Web Desktop and will be expanding to other platforms in the future.

-Data indicates that ~40% of customers abandon the Sample Builder due to the challenging nature of the configuration process, particularly during the Microsoft Bookings setup. To address this issue, we've implemented a solution that streamlines the deployment process by levering Rooms for direct virtual appointment creation within the Sample Builder. This change results in a significant reduction of deployment time, as the configuration of Microsoft Bookings isn't enforced, but rather transformed into an optional feature that can be configured in the deployed Sample. Additionally, we've incorporated a feedback button into the Sample Builder and made various enhancements to its accessibility. With Sample Builder, customers can effortlessly customize and deploy their applications to Azure or their Git repository, without the need for any coding expertise.

 ACS Call Automation can be used to build calling workflows for customer service scenarios, as depicted in the following high-level architecture. You can answer inbound calls or make outbound calls. Execute actions like playing a welcome message, connecting the customer to a live agent on an ACS Calling SDK client app to answer the incoming call request. With support for ACS PSTN or Direct Routing, you can then connect this workflow back to your contact center.
