Tel uri Scheme

The uri scheme "tel" describes resources identifed by telephone numbers. tel:scheme was actually copied from the Japanese i-Mode standard. tel: uri-scheme is supported by most mobile devices; upon activation, the user will receive a confirmation alert to place the outgoing call (to prevent black design patterns). The example below uses the international format: (+) (country code) (local area code) (local number), like so:


<a href="tel:+1800229933">Call us free!<a/a>

Note: in mobile devices that do not have a phone (iPod Touch, iPad, etc.), activating a link using the tel:scheme should trigger a prompt indicating actions (Create New Contact, Add Existing Contact, etc).
