Agent settings and voices

Instructions and greeting

Describe the business goal, answer boundaries and escalation behavior in Role and instructions. Set the welcome message separately, select a knowledge source and save.

Model and conversation language

Compare the models and displayed input/output token rates. Smaller models can cost less; test the same booking scenario on each. OpenRouter options are not free to customers: the displayed tariff applies from the first request.

Choose Turkish, English, German, Spanish, French or Portuguese for a single-language agent. Use Multilingual · Automatic for language switching. Model, voice and speech-recognition language coverage differ; test each target language.

Voice library

Filter by provider and native accent language, then choose a preview language and listen. Speaking a language does not guarantee a native accent. Test names, addresses and numbers in a real conversation.

Conversation flow and tools

Configure who speaks first, greeting delay, minimum response wait and interruption sensitivity. Silence reminders and ending on silence are not a total call-duration limit.

Functions and tools supports ending a call, transfer, DTMF, custom APIs and Cal.com tools. Transfer and DTMF require a telephone call; transfer also depends on carrier SIP REFER support.

Saved changes apply to subsequent calls. Test in the browser and then on a real phone.
