How to make the phone hyperlink inserted in PDF work on the desktop? How to treat this error as a feedback message?

[Ericsson Wursthorn]

Hello! I created a virtual business card in PDF. I put a button to trigger the smartphone phone. When I open the PDF on the mobile phone and click the make call button it works perfectly, but when I open this PDF on the desktop it doesn't work. Does anyone know how I can handle this error if my client accesses the file on computers? I thought of showing a message with the phone number when giving the error. Thank you!

Provided that there is an application that can handle the HTTP native URL of "tel:" then you should get a response on the computer desktop.

However, if you want give a message then you will want to use JavaScript with "app.launchURL();" method and construct the exception error message that you want to display if it fails.

The basic JavaScript would be something like this:

app.launchURL("1-123-456-7890");
