Configure Call Settings

Updated: Dec 10, 2025 Calling is not enabled by default on a business phone number Use the POST /<PHONE_NUMBER_ID>/settings endpoint to enable Calling API features on a business phone number. Calling Eligibility To qualify for Calling API features, your business must have a messaging limit of at least 2000 business-initiated conversations in a rolling 24-hour period. Learn more about Quality Ratings and Messaging Limits When you test your WhatsApp Calling integration using public test numbers (PTNs) and sandbox accounts, Calling API restrictions are relaxed.

Overview

Use these endpoints to view and configure call settings for the WhatsApp Business Calling API. You can also configure session initiation protocol (SIP) for call signaling instead of using Graph API endpoint calls and webhooks.

Configure/Update business phone number calling settings

Use this endpoint to update call settings configuration for an individual business phone number. WhatsApp clients reflecting latest calling config After call configuration is updated, WhatsApp users may take up to 7 days to reflect that configuration although most users refresh much sooner. You can force an immediate refresh in WhatsApp by entering the chat window with business and open the chat info page. Regardless of WhatsApp client behavior, the semantics of settings are still honored on the server side.

Body parameters

Parameter	Description	Sample Value
`status` String	Optional Enable or disable the Calling API for the given business phone number.	`“ENABLED”` `“DISABLED”`
`call_icon_visibility` String	Optional Configure whether the WhatsApp call button icon displays for users when chatting with the business. View call icon visibility behavior details below	View call icon visibility behavior details below
`call_icons` String	Optional Configure whether WhatsApp call button icon displays for users when chatting with the business. View call icons visibility behavior details below	View call icons behavior details below
`call_hours` JSON object	Optional Allows you specify and trigger call settings for incoming calls based on your timezone, business operating hours, and holiday schedules. Any previously configured values in `call_hours` will be replaced with the values passed in the request body of this API call. View call hours behavior details below	View call hours behavior details below
`callback_permission_status` String	Optional Configure whether a WhatsApp user is prompted with a call permission request after calling your business. Note: The call permission request is triggered from either a missed or connected call. View callback permission status behavior details below	`“ENABLED”` `“DISABLED”`
`sip` JSON object	Optional Configure call signaling via signal initiation protocol (SIP). Note: When SIP is enabled, you cannot use calling related endpoints and will not receive calling related webhooks. Learn how to configure and use SIP call signaling	``` “sip”: { “status”: “ENABLED	DISABLED (default)”, “servers”: [// one server per app] { “hostname”: SIP_SERVER_HOSTNAME “port”: SIP_SERVER_PORT, “request_uri_user_params”: { “KEY1”: “VALUE1”, // for cases like TGRP “KEY2”: “VALUE2”, } } ] } ```

Calling status

When the status parameter is set to “ENABLED”, calling features are enabled for the business phone number. WhatsApp client applications will render the call button icon in both the business chat and business chat profile. When the status parameter is set to “DISABLED”, calling features are disabled, and both the business chat and business chat profile do not display the call button icon. Updates to status will update the call button icon in existing business chats in near real-time when the business phone number is in the WhatsApp user’s contacts. Otherwise, updates are real-time for a limited number of users in conversation with the business, and are eventual for the rest of conversations.

Call button icon visibility

When Calling API features are enabled for a business number, you can still choose whether to show the call button icon or not by using the call_icon_visibility parameter. Note: Disabling call button icon visibility does not disable a WhatsApp user’s ability to make unsolicited calls to your business. The behavior for supported options is as follows: DEFAULT The Call button icon will be displayed in the chat menu bar and the business info page, allowing for unsolicited calls to the business by WhatsApp users.

DISABLE_ALL The call button icon is hidden in the chat menu bar and the business info page, and all other entry points external to the chat are also disabled. Consumers cannot make unsolicited calls to the business. Your business can still send interactive messages or template messages with a Calling API CTA button.

Callback permissions

Calling a WhatsApp user requires explicit permission from the user. One way to obtain calling permissions is to request permission when a WhatsApp user calls your business. You can configure the call permission UI to automatically show in the WhatsApp user’s client app when they call your business number. The user may change their permission selection at any time.

Call Icons

With the call_icons setting, you can specify the countries where these icons should show up.

"call_icons": {
  "restrict_to_user_countries": [\
    "US",\
    "BR"\
  ]
}

Parameter	Description	Sample Values
`restrict_to_user_countries` List of Strings	Optional Restrict the visibility of call icons to these countries. NOTE: For example if you restrict it to “US,” then it will apply to all the people who have a US registered phone number. These people could be physically located inside or outside of the USA.	Restrict to US and Brazil: `<br />"restrict_to_user_countries": [<br /> "US",<br /> "BR"<br />]<br />` No restriction: `<br />"restrict_to_user_countries": []<br />`

Call hours

With the call_hours setting, you can specify the timezone, business operating hours, and holiday schedules that will be enforced for all user-initiated calls. Configuring this setting restricts calls only to available weekly hours you configure. User-initiated calls are unavailable outside of the weekly hours and holiday schedules you set. The WhatsApp client app will show users an option to chat with the business, or request a callback, if callback_permission_status is ENABLED. The user will also be shown the next available calling slot on the option screen.

"call_hours": {
  "status": "ENABLED",
  "timezone_id": "America/Manaus",
  "weekly_operating_hours": [\

Configure and use call signaling via session initiation protocol (SIP)

Session Initiation Protocol (SIP) is a signaling protocol used for initiating, maintaining, modifying, and terminating real-time communication sessions between two or more endpoints. You can send and receive call signals using SIP instead of Graph API endpoints. Learn more about how to use and configure SIP

Settings update webhooks

You can subscribe to a new webhook subscription field account_settings_update to get notified on updates to phone number settings. You’ll be notified even for your own updates Currently only changes to calling settings are supported. Underneath the calling object, only changes to subset of fields are observed - status, call_icon_visibility, callback_permission_status, sip.status, srtp_key_exchange_protocol

Steps to get started

Set up your webhook subscription and subscribe to the account_settings_update field. The same app should also be subscribed to the WhatsApp Business Account of your business phone number. Your app should have whatsapp_business_management permission to receive the webhooks. Using access token for the same app, if you’re able to get settings successfully, your app is good to receive the webhooks too.

Calling Restrictions for Low Call Pickup Rates

When calling is enabled on your business phone number, you are expected to pick up calls that users place to you. If a significant number of calls placed to your calling-enabled business phone number are not picked up, we will notify you and expect you to make a change.

What happens if you do not pick up calls

Warning via Email: We will first notify you via email and provide options for you to change how you handle incoming calls. Calling becomes restricted on the business phone number: The calling button will be hidden from users.

How to mitigate the situation

If you receive a warning

Continue allowing users to call: Please identify and address the cause of calls not being picked up and make sure you are properly resourced to handle expected call volumes. Hide call buttons for user-initiated calls: You can do so either by working with your partner or going to WhatsApp Manager > Account tools > Phone numbers > select Phone number [WA phone number] > Calls > toggle off Display call buttons. Turn off calling altogether: You can do so either by working with your partner or going to WhatsApp Manager > Account tools > Phone numbers > select Phone number [WA phone number] > Calls > toggle off Allow voice calls.

If the call button is hidden for the business phone number

Re-display calling buttons: Please identify and address the cause of calls not being picked up and make sure you are properly resourced to handle expected call volumes. Next, display the calling buttons by either working with your partner or going to WhatsApp Manager > Account tools > Phone numbers > select Phone number [WA phone number] > Calls > toggle on Display call buttons. Turn off calling altogether: You can do so either by working with your partner or going to WhatsApp Manager > Account tools > Phone numbers > select Phone number [WA phone number] > Calls > toggle off Allow voice calls.
