Send voice tasks

Usage notes

• Number mode limitations: The task center supports sending tasks only by using a service instance. Regular numbers and 400 numbers are not supported.

• Outbound mode limitations: Shared mode does not support sending tasks in batches. For batch operations, you must use templates configured for dedicated mode.

• Verification type limitations: This feature requires enterprise real-name verification.
