Syntax Implementation

Click to Dial Functionality

To enable the click to dial functionality, use the following syntax:

wtai://wp/mc;number

This code can be embedded into any valid WML tag that implements href or a hyperlink such as <a> tag, <anchor>, <do>, <option>, or <onevent> tags by associating these tags with a <go> tag.

Click-to-dial using <a> tag:

Click on the link below to originate a call

<a href=”wtai://wp/mc;5551212”>Call 5551212</a>

</p>

</card>

</wml>
