Once connected to the console, the Agent can send an email or SMS containing a unique URL to the Guest. This URL contains a 6-digit identifier that allows the established call to launch with a simple click.
Unless otherwise specified, the 6-digit code is valid for one call. The Guest will not be able to call the Agent again once the call is finished.
To begin the call, the Agent clicks on the 
button to send the code to the Guest with following details:
- Call scenario: If only one scenario is selected, leave this option to default.
- Notification type: Email or SMS
- Email or phone number of the Guest
The Agent then clicks “Send SMS” or “Send email”.
Once the SMS or email is received on the Guest side, a simple click on the link will automatically start the call via the Visual Support App.
