### Answer To end calls triggered by a batch call, you configure the End Call tool on your agent. The batch call system initiates the calls, but the agent's prompt and tools control when each individual call ends. Steps to configure automatic call termination: 1. Add End Call Tool – Click "+ Add" in the tools section and select "End Call" from the dropdown menu. [(1) ]() 2. Configure Termination Conditions – Define specific conditions under which the call should be terminated. For example: "If the user says 'thank you', 'goodbye', or 'bye', use the end_call tool to terminate the conversation." 3. Update the Prompt – Incorporate the end call conditions into the agent's prompt with specific instructions such as: "If the user says 'thank you', 'goodbye', or 'bye', use the end_call tool to terminate the conversation." By default, the agent won't end the call automatically—you need to configure when and how the call should be terminated using the end call tool.
