Which function is NOT performed by Lambda functions in Salesforce for handling voice calls?

Lambda functions in Salesforce are designed to handle various tasks related to voice call management, especially in integration with Service Cloud Voice. The primary purpose of Lambda functions is to execute specific actions in response to events, such as handling voice call data and performing operations on that data.

Creating a voice call record in Salesforce is a fundamental function of Lambda, enabling it to capture details of incoming or outgoing calls effectively. Starting real-time transcription is another core capability, allowing the system to convert voice conversations into text, thereby facilitating better record-keeping and analysis. Syncing data between a contact trace record and a VoiceCall record ensures that all relevant information about the call is accurately tracked and accessible for further customer relationship management tasks.

In contrast, managing user login permissions does not fall within the scope of Lambda functions. This function pertains more to user authentication and access control within the Salesforce ecosystem, which is typically handled by other security and user management features in the platform rather than Lambda functions that focus on transactional and operational tasks related to voice calls.
