Agent configuration issues. Common UCCE issues related to agent configuration include incorrect skill group assignments, incorrect agent state configurations, and incorrect agent desktop configurations.
These issues can result in agents receiving calls they are not qualified to handle or being unable to receive calls at all.

The role of CVP in UCCE/PCCE is queuing and self-service IVR, as it provides voice response applications that can interact with callers, collect information, and queue calls for treatment by agents or other destinations.

A Account Type is one of the usages for Call Studio Database lookup, as it allows the application to retrieve information about the caller's account from a database and provide different treatments based on the account type. D Claim Number is another usage for Call Studio Database lookup, as it allows the application to validate the claim number entered by the caller against a database and provide confirmation or error messages accordingly.
