title: "tel:" URLs lead to error page on non-mobile browsers
body: <p>On <a href="http://dh-creative-webdesign.de/rw-fliesen.html" rel="nofollow">this</a> site, I have a link to a phone number for mobile devices in the top right corner where the mobile number is displayed. On desktops, when clicking on this link Chrome just ignores the link but firefox and internet explorer redirect to an error page.</p>
  
  <p>HTML:</p>
  
  <pre><code>&lt;a href="tel:+491796737741" class="contact-info" &gt;&lt;/a&gt;
  </code></pre>
  
  <p>CSS:</p>
  
  <pre><code>#header .contact-info { width: 293px; height: 133px; display: block; float: right; cursor: pointer; background: url(contact-info.png) 0 0 no-repeat transparent; margin-right: 20px; margin-top: 110px; }
  </code></pre>
  
  <p>How can I fix this?</p>
