The JavaScript below contains the template that must be used when setting up the tracking script.
<script type="text/javascript">
var _ctq = _ctq || [];
_ctq.push(['setSiteId', Site ID]);
_ctq.push(['requires', [Group 1, Group 2, ..]]);
// Insert calls to replacement methods here
_ctq.push(['trackPageView']);
(function() {
var wca = document.createElement('script'); wca.type = 'text/javascript'; wca.async = !0;
wca.src = "//web-call-analytics.com/wca.js";
var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(wca, s);
})();
</script>
Calls to replacement methods (described in the Methods section) must be inserted into this tracking script to enable number switching.
