Click on the patient's mobile number on his file,

It gives two options:

The first is to send a WhatsApp message, open WhatsApp and send the message. This service is 100% working. Thank you

The second option is to call by phone. We ask to open an application from Windows in order to call. This service is not active. It is necessary to link it through the API to applications that allow communication from the computer directly, because there are cloud exchanges that we subscribe to, and it has an application on Windows. How can we link it to the application by calling directly to the patient from his file through other applications

The app is called Grandstream wave

And thanks
