# How to add a Phone Number for Testing in Dapta {% embed url="" %} *** You can test your Voice Agent by receiving a real phone call on your device, and these test calls do **not consume any credits**. This allows you to validate your agent’s behavior safely before using it in live campaigns. This is useful for: * Testing voice tone and clarity * Validating scripts * Reviewing conversation flow * Hearing the agent in a real call environment *** ### What This Test Does When you use the **Test Call** feature: * The agent calls your phone * The conversation runs exactly like a real outbound call * No credits are consumed * The call is labeled as a **Test Call** in your call logs This makes it safe to experiment and refine your agent. *** ### Step 1: Go to the Phone Call Tab 1. Open your Voice Agent 2. Click on the **Phone Call** tab 3. Click on **Add a Test Number** *** ### Step 2: Add Your Phone Number * Enter the phone number where you want to receive the test call * Once added, the number will appear in the test number box This is the number the agent will call. *** ### Step 3: Start the Test Call Click **Start Phone Call**. You will receive an incoming call from the system. Once you answer: * The AI agent will begin the conversation * The call will behave like a real outbound call * You can interact naturally with the agent *** ### Step 4: Confirm No Credits Were Used After ending the call: 1. Go to your **Call Log** 2. Find the most recent call 3. You will see: * It is labeled as a **Test Call** * It consumed **0 credits** This confirms that test calls do not affect your credit balance. *** ### Important Notes * Test calls are only for validation * They cannot be used for bulk outreach * For real outbound calling at scale, you must set up a campaign *** ### Key Takeaways * Test calls do not consume credits * You can test agents using your real phone * Call logs clearly label test calls * This is the safest way to validate agent behavior before going live ## Step-by-step process: {% embed url="" %} --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
