Build, Configure, and Deploy Your Voice-Based AI Agent
A Voice Agent 🎙 lets you hold real-time spoken conversations with customers, either:- Through a voice-enabled web widget on your website
- Over the phone via telephony integration (currently Twilio)
- Through a custom SIP connection (available on request for other telephony systems, e.g. Avaya, Cicsco, and Genesys, or mobile apps. Use the contact us form or click on support button on the top right side of the page to request a custom integration).
⚠️ Important: Voice agents cannot be connected to social channels or messaging apps such as WhatsApp, Messenger, or Instagram. They are designed only for website and phone use.
1️⃣ Basic Configuration – Define Your Agent’s Identity & Behavior
This section is where you give your voice agent its identity, role, and communication rules.🏷 Agent Name (Required)
- Internal use only – This name appears in your Wittify dashboard, not to customers.
- Choose a clear, descriptive name so you can identify the agent later (e.g.,
Website Voice Support,Sales Voice Bot – EN/AR). - Avoid generic names like “Agent 1” — be specific so your team knows its purpose.
- This name is not shown to end users.
🧠 Core Instructions (Required)
This is the System Prompt — the “brain” of your voice agent. Think of it as training a new employee: you must clearly explain how they should do their job. Include:- Role & Goal – What’s the main purpose? Support, sales, bookings, lead qualification, etc.
- Tone & Style – Warm, professional, formal, casual, energetic — match your brand’s voice.
- Language & Dialect – Be specific (e.g., English – US, Arabic – Saudi, Arabic – Egyptian).
- Speech Style – Should the agent give short and concise answers or longer, detailed explanations?
- Boundaries – Topics it must avoid (e.g., no legal or medical advice, no personal opinions).
- Compliance Requirements – Reference company policies or industry regulations it must follow.
💡 Guidance:
- Be precise — vague instructions cause inconsistent answers.
- Write in full sentences.
- If your business requires disclaimers, include them here.
🛠 Use Pre-Built Templates (Optional)
- You can start faster by applying a ready-made role (e.g., Customer Support Agent, Sales Agent).
- After applying, edit the Core Instructions to match your specific business needs and policies.
- Templates save time, but always customize for accuracy.
🎨 Creativity Level (Temperature)
Controls how precise or creative the agent is:- 0.0 – 0.3 → Deterministic, factual answers (best for policies, FAQs).
- 0.4 – 0.6 → Balanced, flexible but reliable (good for most customer service).
- 0.7 – 1.0 → Highly creative, more varied responses (marketing, brainstorming).

⚙ Advanced Voice Settings
These settings let you fine-tune the flow and responsiveness of the call:- End Call on Silence (seconds) – How long to wait if no one speaks before ending the call.
- Max Call Length (minutes) – The total duration limit for the call.
