Hello,
it don't active click to dial for call. I have a VF page (OpenCti) that active this function. This page load like CTI.

In sandbox click to dial active nothing problem and perfect work.

The VF page is:
<apex:includeScript value="/support/api/30.0/interaction.js"/>
<script>
sforce.interaction.cti.enableClickToDial(callback);
var callback = function (response) {
 };
sforce.interaction.cti.onClickToDial(listener);
var listener = function (response) {
    alert('it's work's');
};

Why not work's click to dial in production?
Thank's
