Voice studio: agent settings
Custom brief text, tools and MCP servers, speech, call and transcription settings.
Open Voice studio, "Agent". The fixed flow with the approved script is the normal case. Your own text only runs without an approved script. The AI disclosure, opt out handling and legal rules always stay in place. The page has the tabs "Brief text", "Tools & MCPs", "Speech", "Call" and "Transcription".

Steps
1. Brief text
Switch on "Use my own brief" and write your text for "Outbound calls" and for "Hotline" (up to 6000 characters each). Click "Show the default script" and "Use as a starting point" to begin from ours. Click "Save brief". "Reset to default" deletes your own text for good. Headings starting with "#" are removed.
2. Tools & MCPs
Under "Built in tools" choose what the agent may do: Check free slots, Confirm email address, Book meeting, Schedule callback, Transfer to a human, Record outcome, Record email consent, Register opt out and End call. Tools marked "Always on" are required by law or for a clean end of the call. Click "Save tools". The tab also lists connected integrations and the endpoints of your own API.
3. Add an MCP server
Click "Add MCP", enter name, URL (https only; internal addresses are refused), transport (Automatic, SSE, Streamable HTTP), HTTP headers and the connection timeout (1 to 10 seconds, default 3). Click "Create server", then "Test connection". Tick the tools the agent may call (nothing ticked means all) and click "Save selection".
4. Speech
Set background sound (None, Office, Café) and volume, response eagerness, interruption sensitivity, the reminder on silence, and pronunciations (word and how it is spoken). Click "Save speech settings".
5. Call
Set voicemail detection (Leave a message or Hang up), Hang up on IVR, Learn from our own calls, keypad input detection, end call on silence, max call duration and ring duration. Click "Save call settings".
6. Transcription
Choose denoising (Off or Remove noise (SIP)) and add boosted keywords such as product names. Your company name and rep are always included. Click "Save transcription settings".
Fields and options

1 to 10. Higher is faster but more likely to talk over the person.
