Hey there! Let's break down your questions about RingCentral's call forwarding functionality clearly:

1. How to implement "Forward to Other's Phone" via RingCentral API #

The "Forward to Other's Phone" (formerly "Forward to other user's phones") feature maps directly to forwarding calls to another user's extension in RingCentral's Call Handling Settings. Here's how to set it up with the REST API:

• Use the PUT /restapi/v1.0/account/{accountId}/extension/{extensionId}/call-forwarding endpoint to update your call forwarding rules.
• In the request body, define a forwarding number with the type UserExtension and link it to the target user's extension details.

Example Request Body #

{
  "forwarding": {
    "forwardingNumbers": [
      {
        "type": "UserExtension",
        "extension": {
          "id": "TARGET_EXTENSION_ID" // Replace with your colleague's extension ID
        },
        "phoneNumber": "TARGET_EXTENSION_PHONE_NUMBER", // Optional for clear labeling
        "label": "Colleague's Extension"
      }
    ],
    "notifyMySoftPhones": false, // Adjust based on your preference
    "notifyAdminSoftPhones": false
  }
}

Ensure your API credentials have permissions like EditCallHandlingSettings or EditExtensions to modify these configurations.

2. Is there an API call that mimics the UI's "Forward to Other's Phone" button? #

Good news—the UI button you're referencing uses exactly the same call forwarding API endpoint we just covered. When you click that button in the Online Account Portal, the backend sends a PUT request to update your call forwarding rules with a UserExtension-type forwarding number.

Since you already know how to add/edit standard forwarding numbers, you just need to switch the type parameter from external number types (like Other) to UserExtension, then reference the target user's extension ID or number. There's no special "hidden" API for this UI action—it's all handled via the standard call forwarding endpoints.

Quick Note on Legacy UI Names #

The old "Forward to other user's phones" option is functionally identical to the new "转接至他人电话" feature—both use the same API parameters to route calls to another user's extension.
