The Voice Configuration page (Channels > Voice > Voice configuration) controls voice-specific settings including model selection, greeting, and disclaimer behavior.
Greeting and disclaimer settings are now in Voice Configuration, separate from shared agent configuration.

Model selection

Select the language model that powers your voice agent.
Large language model
dropdown
Choose the LLM for voice conversations. All available models are listed here, including PolyAI’s Raven models.
Raven models are purpose-built for conversational AI. Raven V2 and V3 are only available here, while Raven V3.5 is also tuned for chat and can be selected in Chat configuration.
For a full list of available models, see the Model page.

Voice greeting

Configure what your agent says when a call begins.
Greeting message
string
The first thing your agent says when answering a call.Example: “Thank you for calling. How can I help you today?”
Keep your greeting concise. Long greetings can frustrate callers who want to get to the point quickly.

Voice disclaimer

Configure a disclaimer message that plays at the start of calls.
Disclaimer message
string
A message informing callers about call recording or other legal requirements.Example: “This call may be recorded for quality and training purposes.”
Disclaimer voice
string
You can use a separate voice for the disclaimer to distinguish it from the main assistant voice. Configure this in Agent Voice.

Call handling settings

Additional settings that affect how calls are handled:
  • Silence timeout - How long to wait during silence before prompting the caller
  • Max call duration - Maximum length of a call before automatic termination
  • End of call behavior - What happens when a call ends (e.g., trigger CSAT survey)

Environment behavior

Voice configuration follows the same branching behavior as other channel settings:
  • Make changes in Sandbox for testing
  • Promote to Pre-release for UAT
  • Deploy to Live for production
