Wireless Telephony Applications (WTA)

Wireless Telephony Applications (WTA)

Wireless Telephony Applications (WTA) are those applications designed to interact with the telephony-related functions present in a phone. The web browser supports:

Originating a call - Click to Dial
Adding entries to the phonebook (Add to Speed Dial entries)

The Web Browser supports the WTA application “click to dial” any link on the screen. An icon of a telephone handset is displayed to the left of a “click to dial” link when the link is initially displayed.

The Add to Phonebook WTAI function “wtai://wp/ap;” is used to add a Name and Number to the 4620 Speed Dial application. A Speed Dial icon will be displayed to the left of an “add to phonebook”. The wtai syntax is supported as a href attribute and as such any tags that support the href attribute will be able to use the “add to speed dial” function. These tags are <a>, <anchor>, <img>, <do>, <onevent>, <select>, <option>, and <optgroup>.

When a user activates the “add to speed dial” function, the web will transfer the name and number to the Speed Dial application, and the user will have the opportunity to edit the entry according to the current Speed Dial functionality.
