# Steps for Adding Collaborators on WebRTC Exotel

***

### Background

Exotel allows updating agents only through API calls.\
Agents created directly on the Exotel dashboard do not automatically link to an **app\_id** or **webrtc\_sdk\_id**.

If agents are already added on Exotel and an inbox is subsequently created on LimeChat CRM, LimeChat will not be informed about these users by Exotel.

To link agents with the required **app\_id** or **webrtc\_sdk\_id**, a specific sequence of actions must be followed. This ensures proper configuration and functionality of the WebRTC-based calling system.

***

### Steps for Adding Collaborators

#### **Case 1:** For customers new to Exotel - 

Where the agents are still not added to the Exotel dashboard or whose users were deleted before creating the inbox, as mentioned in [Exotel WebRTC Calling - Setup Guide](/limechat-product-guide/helpdesk/inboxes/voice-calling-inboxes/exotel-webrtc/exotel-webrtc-calling-setup-guide.md)

1. **Use the LimeChat UI for Onboarding:**
   * Add collaborators directly via the LimeChat UI using the process defined here: [User Roles: Setup Guide](/limechat-product-guide/helpdesk/settings/user-roles-setup-guide.md)
2. **Automatic Agent Creation:**
   * The LC system will automatically create agents on the Exotel dashboard with the appropriate **app\_id** or **webrtc\_sdk\_id**.

***

#### **Case 2: Existing Clients on Exotel - Users are already present on Exotel Dashboard**

For customers already using Exotel, follow these steps based on their requirements:

#### **Method 1: Recreate Agents to Link `app_id`**

1. **Delete Existing Agents on the Exotel Dashboard:**
   * Remove all existing agents to ensure no conflicting entries remain.
2. **Create a New Inbox in LimeChat:**
   * Set up a fresh inbox tied to the appropriate `app_id` or `webrtc_sdk_id`.
3. **Add Collaborators to the New Inbox:**
   * Use the LimeChat UI to add collaborators.
   * This action will automatically recreate agents on the Exotel dashboard, linked to the correct **app\_id** or **webrtc\_sdk\_id**.

**Method 2: Reach out to Exotel support and link new `app_id` with existing Users**

* Coordinate with Exotel to manually link the required **app\_id** with the existing users on their platform.
