I am interested in creating links to phone numbers in order to start making phone calls for users browsing a mobile site.
What is the difference between tel and wtai URL schemes ? Are there other schemes?
How to use them and in what circumstances?
Do some devices recognize only one circuit or another circuit, outdated or probable?

Apple URL Schema Link
The AFIK WAPI WTAI specification refers to the wap protocol, and if the phone supports WAP / WML, it will support WTAI.
