Hover to call

When the user hovers on a telephone number (or other indication of a target of voice communication) on a web page (or other interface), telephone number will be highlighted and user will be provided with the opportunity to make a call using the highlighted number. If user clicks on the highlighted telephone number, the telephone number will be provided to a communication application to facilitate making a telephone call. If the user moves away without clicking on the highlighted telephone number, the highlight will disappear. In alternative embodiments, a user can select text in a web page (or other interface) and, if there is a telephone number in the selected text, that telephone number can be automatically provided to the communication application to facilitate making a call. In another embodiment, the system finds telephone numbers in content and replaces those telephone number with hyperlinks to enable the behavior described above.
