## Additional considerations

### Transactional vs Marketing and Recruitment Robocalls

Before configuring a robocall, consider the purpose of the message and its intended audience. If the call is marketing/recruitment-related, be sure you have a mechanism to log and act on opt-out information.

Currently, it is not possible for a call recipient to opt out during a call.

For additional best practices, see the [Maintaining Compliance for SMS](/v1/docs/maintaining-compliance-for-sms-voice#robocalling-and-tcpa-compliance) article which discusses robocalling and compliance with the Telephone Consumer Protection Act (TCPA).

### Delivery Statistics

There is no capability on any platform for detecting "opens" with voice messages.

### Recipient Data Fees

The recipient may incur usage fees from their mobile provider for any voice calls received.

### Answering Machine / Voicemail Detection

Slate robocalling can detect if a call is answered by a person or by a voicemail service. For this detection to work, Slate must first receive audio from the recipient’s end.

If Slate detects a human answering the phone, it will begin playing the recorded message immediately.

If Slate detects an answering machine or voicemail, it will wait for the indication sound (“beep”) to begin the entire recorded message.
