Start a phone call from a WebApp

Is it possible to dial a number and start a phone call from a xojo webapp running in a mobile browser ?
Thanks for any tip anyone could give me.

Try ShowURL(“tel://584838”) replace the numbers with a phone number and try…:wink:

Just for anyone searching in future, there are some more of these URL schemes, including FaceTime (audio and video), Maps and more.

Gavin… NICE link !!! Thanks
