Making Calls Using RingOut

Last updated: 2020-09-25Contributors

The RingOut option enables the users to make a call from any other outside number (not RingCentral number) by means of the RingCentral account, when it is not convenient for them to use the RingCentral number. This feature is available for softphone, web service and mobile applications.

The user specifies a certain number under the forwarding number list, starts RingOut and enters the required called number. RingCentral makes a call to the specified forwarding number and connects the user with the called number.

The API treats a two-legged RingOut call as a resource that can be created, retrieved, or deleted via the POST, GET and DELETE methods correspondingly.

Sample Code to Get Started with RingOut

The two-legged RingOut call can be created via the following request:

POST /restapi/v1.0/account/~/extension/~/ringout
Content-Type: application/json
Authorization: Bearer <access-token>

    "from": {"phoneNumber": "13445554444"}, /* from parameter is optional if there is a default number in user's forwarding numbers */
    "to": {"phoneNumber": "13455553434"}, /* to parameter is required */
    "playPrompt": true /* optional field */
const RingCentral = require('@ringcentral/sdk').SDK

var rcsdk = new RingCentral( {server: "server_url", clientId: "client_id", clientSecret: "client_secret"} );
var platform = rcsdk.platform();

platform.login( {username: "username", password: "password", extension: "extension_number"} )

platform.on(, async function(response){
        var resp = await'/restapi/v1.0/account/~/extension/~/ring-out', {
                'from' : { 'phoneNumber': "13445554444" },
                'to'   : {'phoneNumber': "13455553434"},
                'playPrompt' : true
        var jsonObj = await resp.json()
        console.log("Call placed. Call status: " + jsonObj.status.callStatus)
from ringcentral import SDK

sdk = SDK( "client_id", "client_secret", "server_url" )
platform = sdk.platform()
platform.login( "username", "extension", "password" )

resp ='/restapi/v1.0/account/~/extension/~/ring-out',
      'from' : { 'phoneNumber': "13445554444" },
      'to'   : { 'phoneNumber': "13455553434" },
      'playPrompt' : True
print "Call placed. Call status: " + resp.json().status.callStatus

$rcsdk = new RingCentral\SDK\SDK( "client_id", "client_secret", "server_url" );

$platform = $rcsdk->platform();
$platform->login( "username", "extension_number", "password" );

$resp = $platform->post('/account/~/extension/~/ring-out',
      'from' => array( 'phoneNumber' => "13445554444" ),
      'to' => array( 'phoneNumber' => "13455553434" ),
      'playPrompt' => true

  • from

    Refers to the number of the calling party. Required field only if there is no default number in the user's forwarding number list. The phoneNumber attribute should comply with the E.164 standard. As a result of validation of the phoneNumber attribute the server may return the error code: 400 Bad Request - phoneNumber specified in the field is empty or invalid.

  • to

    Refers to the called party number. Required field. If this field is missing from the request, the 400 Bad Request error is returned. The phoneNumber attribute should comply with the E.164 standard. As a result of validation of the phoneNumber attribute the server may return the error code: 400 Bad Request - phoneNumber specified in the field is empty or invalid.

  • playPrompt

    The audio prompt that the calling party hears when the call is connected. Optional field. It corresponds to the setting in the RingCentral application "Prompt me to dial 1 before connecting" (When selected, the system will ask you to press "1" on your phone's key pad before connecting to the destination number).

The response can be as follows:

200 OK
Content-Type: application/json

    "id": 234343434,
    "uri": "/restapi/v1.0/account/~/extension/~/ringout/234343434",
    "status": {  
        "callStatus": "Success",  
        "callerStatus": "Success",  
        "calleeStatus": "Success"   


  • callStatus can take the following values:

    Value Description
    InProgress Connection is being established
    Success Both legs connected (Answered)
    CannotReach Failure state (one or both legs are in invalid state for call connection)
    NoAnsweringMachine Internal server failure
  • callerStatus, calleeStatus can take the following values:

    Value Description
    InProgress Connection to the target leg is being established
    Busy Target device is busy
    NoAnswer The call has been dropped because of timeout
    • RingOut command was canceled by user or
    • RingOut initiated, 1st leg answered, 2nd is ringing, user drops call on the 1st leg - 2nd leg gets 'Rejected'
    Success Call party has answered the call
    Finished The call was terminated (In Progress > Success > Finished)
    • Error code received from PSTN or
    • Internal server error
    • International calling disabled (Call to International number) or
    • Domestic calling disabled (Call with local Country code) or
    • Internal calling disabled (Call within one account)
    NoSessionFound RingOut status was requested for RingOut session which does not exist (e.g was already Closed)
    Invalid RingOut session state is unknown due to internal failure

Call status is generated as a combination of both call legs statuses (caller and callee):

Caller or Callee statuses are separately generated for the target call party:

Polling Call Status

Use polling to get the status of an ongoing outbound call.


The response will be as follows:

200 OK
Content-Type: application/json

    "id": 234343434,
    "uri": "/restapi/v1.0/account/~/extension/~/ringout/234343434",
    "status": {  
        "callStatus": "Success",  
        "callerStatus": "Success",  
        "calleeStatus": "Success"   

How to cancel a RingOut in progress

RingCentral does not currently support call control for outbound calls. However, you can cancel a RingOut call while the callee's party status is InProgressby making a DELETE request to the RingOut endpoint as shown below:

DELETE /restapi/v1.0/account/~/extension/~/ringout/234343434  

If successful, the platform will respond with a 204.

Deleting the RingOut is only available when the RingOut has been initiated and the call has not been connected. For example:

If you initiate a RingOut and immediately call the DELETE RingOut endpoint, the call would get terminated as long as the RingOut between the two parties is not connected (first leg has not been established). If the first leg of the call has been initiated, then the DELETE API will not terminate the call.

Caller ID

RingCentral allows users to select which number to use for their Caller Id Name (CNAM) value when making calls. To set the CallerId for the RingOut API, set the "RingOut from Web" value as available in the Online Account Portal. More information on this can be found in KB Article #3471.

RingOut API Permissions

Apps requesting to make a ring-out call require the RingOut permission.
