What is the purpose of the first connected app used with Service Cloud Voice (SCV)?

The primary purpose of the first connected app used with Service Cloud Voice (SCV) is to enable single sign-on (SSO). This functionality is crucial as it streamlines the user experience by allowing agents to log into multiple applications using a single set of credentials. By integrating SSO, organizations can enhance security and simplify access for their users, which is especially important in call center environments where agents need to quickly navigate between systems to assist customers effectively. Implementing SSO through the connected app not only enhances user convenience but also aids in maintaining data integrity and security within the Service Cloud ecosystem.
