Searching for "clickable phone number web application"

  
Is it possible in a web application when you press on a phone number that it will directly call that number? If yes, how?
depends,

make sure it's a +31 phonenumber I think, and samartphones will work instantly.

otherwise...

skype recognizes
<a href="callto:1-408-555-5555">1-408-555-5555</a>

i believe, this works also for iphone

<a href="tel:1-408-555-5555">1-408-555-5555</a>
and also if you want to start a text message <a href="sms:1-408-555-5555">make textmessage</a>
