The extension’s web client credentials can be found in the email titled “New 3CX User Account” sent by the 3CX administrator. This email also contains the voicemail PIN and QR code for the 3CX app. It will be sent to the 3CX administrator’s email address registered in the extension. If you do not receive this email, you will need to send a “welcome email” with your extension number from your administrator. If you have already configured the 3CX app, tap the app menu in the left corner. Then select Settings-> Resend Credentials. Note: 3CX cannot send extension credentials. You will not be able to access the information and data of your company’s 3CX Phone System.
