(html) Tel:phone-number not working

Question

have done a complete search and cannot get this click-to-call html to work. Have tried;

<a href="tel:000000000">000000000</a>
<a href="tel://000000000">000000000</a>
<a href="callto:000000000">000000000</a>
<a href="callto://000000000">000000000</a>

This is the webpage i'm trying to get it to work on http://www.glasgowbuildinginspections.com.au/phone/

I can load the page locally file:///D:/Downloads/index.html and it works, but the page says it can't load server side files which might be what is stopping it. Any thoughts?
