Send a message
You place a voice call with the SendVoiceMessage operation. The service uses
Amazon Polly to convert text to speech, or plays an audio file that you supply, to the destination
phone number. How the service selects an origination identity depends on what you specify in the
request. You can send through a phone pool (recommended), directly from a single origination
identity, or at the account level.
API operations
Use the following API operation to place voice calls.
| Operation | Description | Use for |

Places a voice call that plays text-to-speech or audio you supply. |

Types of send
AWS End User Messaging supports three ways to place a voice call. Each one determines how the service selects the origination identity for your call.
| Type | How it works | When to use |
|---|---|---|
Pool-based (recommended) |
Specify a pool ID as the origination identity. The service selects the best identity from the pool. |
All use cases. Managed selection and compliance-safe routing. |
Direct |
Specify a single origination identity, such as a phone number. |
You want to send from one specific identity. |
Account-level |
Omit the origination identity. The service selects from the identities in your account. |
Simple single-use-case setups. Not recommended when the account has numbers for multiple use cases. |
For full detail and code examples, see Outbound messaging.
