What action does a Lambda function NOT perform?

The Lambda function is a serverless computing service provided by AWS that allows you to run code in response to events, automating various processes and integrating with different services, including Salesforce through its APIs. In this context, the action of deleting old recordings is not a typical task associated with a Lambda function. Instead, Lambda functions are generally used for processing data such as invoking APIs, saving information, or creating records based on events.

The other actions—invoking the Salesforce REST API, saving transcripts to Salesforce, and creating a voice call record—are all representative of the capabilities or intended uses of a Lambda function. The function can trigger events that involve communicating with Salesforce APIs to save data or create records based on the interactions between voice calls and the Salesforce environment.

Consequently, while Lambda functions can perform a variety of data management and API interaction tasks, the specific action of deleting old recordings is not directly aligned with the core functionalities typically executed by Lambda functions in the context of Service Cloud Voice and integration with Salesforce.
