Use Web Call to Test Voice AI Agents Without Buying a Phone Number

Modified on: Mon, 23 Mar, 2026 at 9:17 AM

Test your Voice AI agent instantly in HighLevel without buying or assigning a phone number. Web Call lets you launch a browser-based trial call so you can validate prompts, settings, and call behavior faster while building your agent. This is ideal for quick iteration during setup, especially when you want to hear the live experience before moving to phone-based testing or production use. HighLevel already supports Web Call as one of the testing methods available for Voice AI agents.


TABLE OF CONTENTS


What is Web Call?


Web Call is a browser-based trial calling option for HighLevel Voice AI agents. It allows you to speak with your agent directly from the browser instead of dialing a phone number. This makes testing faster and more accessible when you want to validate prompts, actions, and conversation flow during setup.

Web Call is designed for testing, not as a replacement for live telephony. This distinction helps users understand that browser-based trials are for validation, while live calling still follows HighLevel’s production calling requirements.


Key Benefits of Web Call


Web Call helps you test faster and refine your Voice AI experience before going live. It removes extra setup friction during agent creation and makes it easier to validate changes as you tune prompts, goals, and actions.


  • No phone number required: Start testing your Voice AI agent without purchasing or assigning a phone number first.

  • Faster validation: Launch a trial call immediately in the browser so you can review how the agent responds in real conversations.

  • Supports most testing scenarios: Web Call supports agent testing for prompts, call flow, and actions, with the exception of call transfer.

  • Useful during setup: Web Call is especially helpful while creating a new Voice AI agent because it lets you test before finalizing phone-based calling.

  • Instant feedback: After a test, you can review logs, transcripts, and recordings to improve the agent experience.



How Web Call Works


Understanding how Web Call behaves during testing helps you interpret results more accurately. This includes how HighLevel identifies the caller, what features are supported, and where your test activity appears after the call ends.


  • Web Call runs directly in your browser as a test method for a Voice AI agent.

  • The logged-in user’s contact is automatically used as the caller contact during the trial.

  • Most agent actions can be tested using Web Call.

  • Call transfer is not supported during a Web Call trial.

  • Test calls can be reviewed later in Voice AI logs, including transcripts and recordings.

  • Test calls do not count toward dashboard analytics or performance metrics.


Supported Features and Current Limitation


Knowing what Web Call can and cannot do helps you choose the right testing method. Browser-based testing is excellent for fast iteration, but some telephony-specific behavior still requires a phone-based test.


Supported During Web Call


Web Call is intended to mirror the Voice AI testing experience as closely as possible so you can validate prompts, responses, and general call handling without extra setup.


  • Prompt testing

  • Conversational flow testing

  • Action testing for supported agent behaviors

  • Quick iteration during creation and optimization

  • Transcript review and log visibility after the test ends


Not Supported During Web Call


Some functionality depends on telephony behavior that is not available in the browser-based trial experience. This is why Web Call is a fast testing option, while Phone Call remains useful for complete phone-path validation.

  • Call transfer is not supported in Web Call trials.


How To Setup Web Call


Proper setup ensures your browser-based test reflects your agent’s latest prompts and configuration. Before starting the trial, make sure your Voice AI agent has been created and your browser can access your microphone.


  1. Go to AI Employee > Voice AI in HighLevel.

  2. Open the Voice AI agent you want to test.

  3. Locate the testing area for the agent. HighLevel supports both Phone Call and Web Call testing methods.

  4. Select Web Call. Unlike Phone Call testing, Web Call does not require you to enter a phone number.

  5. Allow microphone access in your browser when prompted.

  6. Start speaking with your Voice AI agent and test the prompts, responses, and actions you want to validate.

  7. Review the test results in your Voice AI logs after the call to analyze the transcript and recording.



Reviewing Web Call Test Results


Testing is most useful when you can quickly learn from the outcome and improve your agent. HighLevel keeps test-call details visible in the Voice AI dashboard logs so you can review conversations without affecting your production analytics.

  • Go to Voice AI > Dashboard Logs to review test-call activity.

  • Use the Call Type filter to isolate Test Calls if needed.

  • Open the log entry to review the recording and transcript.

  • Test calls are visible in logs but excluded from dashboard analytics and performance reporting.

No. Web Call lets you test directly in the browser without purchasing or assigning a phone number first.


Q: What is the difference between Phone Call and Web Call testing?
Phone Call tests the agent through a phone-based path, while Web Call launches a browser-based test so you can skip number provisioning and start faster.


Q: Can I test call transfer using Web Call?
No. Call transfer is currently not supported in Web Call trials.


Q: Who is used as the caller during a Web Call test?
HighLevel automatically uses the logged-in user’s contact as the caller contact during the Web Call trial.


Q: Will my Web Call test appear in logs?

Q: Do Web Call tests affect dashboard analytics?
No. Test calls are excluded from dashboard analytics and performance metrics.


Q: Why is my Web Call not starting?
Check whether your browser has permission to use your microphone and confirm you launched the test from the Web Call option inside the Voice AI testing flow.


Q: Is Web Call the same as the Voice AI Chat Widget?
No. Web Call is an internal testing method for Voice AI agents, while the Voice AI Chat Widget is a separate browser-based feature for live website visitor conversations.
