When you receive a Whisbi phone call you will hear a PIN number which you have to type in and then click Connect to start a new session:
example: “Whisbi PIN: 5-6-2-7-4”
This also works for PIN only sessions. In this scenario you will guide your customer to get the pin either from the PIN box in your website or from pin.guru
This may differ if your company is using CTI integration in which case the PIN will be inserted automatically for you.
