Dial-In

The Dial-in option allows meeting participants to join via a phonecall. This is particularly useful if they have internet issues, are traveling, or cannot use video for other reasons.

Dial-in is currently in closed Beta and available to selected customers only. Email us at [email protected] to join our pilot program (terms and conditions apply).

Per room configuration

You can configure the dial-in feature for individual rooms. Use the POST /meetings request to create the new room. During the creation request, add the following fields to the request’s body:

{    
    "endDate": "2099-03-25T13:30:00.000Z",
    “isDialInEnabled”: true,
    "fields": ["dialIn"]
}

Multiple fields can be specified in the same request, including things like hostRoomUrl

Example response:

{
	"startDate": "<now>",
	"endDate": "2099-03-25T13:30:00.000Z",
	"roomName": "/example-room”,
	"roomUrl": "https://example.whereby.com/example-room",
	"meetingId": "1234",
	"dialIn": {
		"code": "1234567890",
		"phoneNumbers": [
			{
				"countryCode": "US",
				"phoneNumber": "111-867-5309"
			}
		]
	},
	"roomPreferences": {
		"dialIn": true
	}
}

Getting details of the dial-in access codes

To obtain the dial-in details and access codes for a specific meeting, use the meetingId and send a GET request with ?fields=dialIn as a query param. The details are provided in a text response in JSON format, and include:

• List of Dial-in phone numbers from different countries that participants can call to join the meeting

• Dial-in access code

The above request will work for both a specific meetingId, or all active meetings. The response will be an array of meetings and the meetings will have the Dial-in details, but only if they were created with Dial-in enabled.

Creating callable links

The phone number and room code can be combined and presented as a link on your website or HTML email, allowing users to 'click' the link and dial into the room without having to manually enter the code.

To do so, create an anchor element with the href set to "tel:<phone number>,<room code>" like so:

<a href="tel:[phone]">Click here</a>

The comma separating the phone number from the room code above, causes the phone to wait for an answer before entering the code

Using webhooks

Webhook events can be used to track dial-in participants. When a dialed-in participant joins or leaves the meeting, Whereby sends a webhook event with details:

• Participant’s phone number

• Participant’s date and time of joining

• Participant’s date and time of leaving the room

Additional information

1. The Dial-in feature currently provides voice messages to participants in English only.

2. The Dial-in feature is not compatible with our Breakout Groups feature.
