After spending 2 hours setting up agents, a phone number, etc, I click on the Make an Outbound Call, enter a number, in the modal, then click Call and… nothing. It just closes the modal after spinning for 2 sec.

There are a dozen errors in the web dev console (but none in the web page UI), including:  
5086-bfa265b429da8999.js:1 POST [https://api.retellai.com/v2/create-phone-call](https://api.retellai.com/v2/create-phone-call) 400 (Bad Request)

What is going on?

The 400 Bad Request error indicates your outbound call request is being rejected due to invalid parameters[(1)](https://docs.retellai.com/api-references/create-phone-call). Here are the most common causes:

## Phone Number Configuration Issues

Your phone number must be properly configured before making outbound calls[(2)](https://docs.retellai.com/deploy/outbound-call). Specifically:

- The `from_number` must be a Retell-managed or imported number[(2)](https://docs.retellai.com/deploy/outbound-call)[(1)](https://docs.retellai.com/api-references/create-phone-call)
- You need to bind an **outbound agent** to your phone number[(2)](https://docs.retellai.com/deploy/outbound-call)
- The number must be in E.164 format (e.g., `+14157774444`)[(1)](https://docs.retellai.com/api-references/create-phone-call)[(3)](https://community.retellai.com/t/retell-sympana-gohighlevel-outbound-call-creates-web-call-error-user-not-joined-no-pstn-ring-phone-mapping-issue/704)

## Required Setup Steps

Before making outbound calls, ensure you’ve completed these configurations[(2)](https://docs.retellai.com/deploy/outbound-call):

1. **Bind an agent to your phone number** : Navigate to your phone number settings and assign an outbound agent[(2)](https://docs.retellai.com/deploy/outbound-call)
2. **Verify number format** : The destination number must be in E.164 format with country code, no spaces or special characters[(1)](https://docs.retellai.com/api-references/create-phone-call)[(3)](https://community.retellai.com/t/retell-sympana-gohighlevel-outbound-call-creates-web-call-error-user-not-joined-no-pstn-ring-phone-mapping-issue/704)
3. **Check international calling** : If calling outside the US with a Retell-purchased number, verify the destination country is in the [15 supported countries](https://docs.retellai.com/deploy/international-call)[(2)](https://docs.retellai.com/deploy/outbound-call)

## Common 400 Error Causes

Based on similar cases, the 400 error typically occurs when[(4)](https://discord.com/channels/1186424376300679209/1370700007765704785)[(5)](https://discord.com/channels/1186424376300679209/1384549347605221438):

- The `from_number` is not a valid Retell phone number[(4)](https://discord.com/channels/1186424376300679209/1370700007765704785)
- No outbound agent is bound to the phone number[(2)](https://docs.retellai.com/deploy/outbound-call)
- The phone number format is incorrect (not E.164)[(1)](https://docs.retellai.com/api-references/create-phone-call)[(3)](https://community.retellai.com/t/retell-sympana-gohighlevel-outbound-call-creates-web-call-error-user-not-joined-no-pstn-ring-phone-mapping-issue/704)
- The destination country is not supported for your number type[(2)](https://docs.retellai.com/deploy/outbound-call)

## Quick Fix

Check your phone number configuration in the dashboard[(2)](https://docs.retellai.com/deploy/outbound-call):

1. Go to “Phone Numbers” tab[(6)](https://docs.retellai.com/get-started/quick-start)
2. Click on your purchased number
3. Under **Outbound Agent** , ensure an agent is selected[(2)](https://docs.retellai.com/deploy/outbound-call)
4. Verify the number shows as active

Hello @ty1

Can enter the number you are calling in the E.164 format, and if the issue is still happening, can you share your org id and a quick video showing how you are doing it.

**Post date:** [February 9, 2026, 9:01pm UTC](https://community.retellai.com/t/make-an-outbound-call-does-nothing/804/4 "2026-02-09T21:01:44Z")

To ensure your phone number is in the correct E.164 format for Retell AI, it should include the country code prefixed with a plus sign (+), followed by the number with no spaces or special characters[(1)](https://docs.retellai.com/api-references/create-phone-number)[(2)](https://docs.retellai.com/api-references/create-phone-call).

For example, a valid E.164 format would be `"+14157774444"`[(1)](https://docs.retellai.com/api-references/create-phone-number)[(2)](https://docs.retellai.com/api-references/create-phone-call).

**Common E.164 formatting issues:**

- Ensure the number includes the `+` prefix followed by the country code[(1)](https://docs.retellai.com/api-references/create-phone-number)[(2)](https://docs.retellai.com/api-references/create-phone-call)
- Remove any spaces, dashes, or special characters from the number[(1)](https://docs.retellai.com/api-references/create-phone-number)[(2)](https://docs.retellai.com/api-references/create-phone-call)
- For a US number, it should look like `"+12137771234"` rather than `"(213) 777-1234"` or `"2137771234"`[(2)](https://docs.retellai.com/api-references/create-phone-call)

If you’re experiencing issues with number format, double-check that there are absolutely no dashes, spaces, or other characters in your phone number[(3)](https://community.retellai.com/t/outbound-batch-call-error-for-us-numbers-despite-valid-e-164-formatting/332).

If you’re using a local VOIP provider that doesn’t automatically provide numbers in E.164 format, you may need to handle normalization on your side with a PBX dialplan or SBC rule[(4)](https://discord.com/channels/1186424376300679209/1444865486499221588). Some users have resolved issues by changing the destination number format to +E.164 in their telephony provider settings[(5)](https://discord.com/channels/1186424376300679209/1395110793262928013).

If the issue persists after verifying the format, please share your org ID and a video showing the steps you’re taking so the support team can investigate further.

If you can share the org id that will be helpful.
