URL not passing to browser

URL not passing to browser

We've got a URL Dialer we've been using via Javascript in Salesforce.com.  I don't believe Zoho supports Javscript yet, so I'm looking to create a clickable URL instead.  The URL format is along the lines of: "phone:John_Doe/+1(800)5551212”.  When I put this into a Zoho URL field, it doesn't click.  It appears you're requiring an http or https.  The URL dialer makes IE recognize "phone" as a valid destination.  Another valid format in HTML would be the following:
 
<A HREF=”phone:John_Doe/+1(800)5551212”>Doe, J</A>
 
If I directly paste the text into a browser it dials the number just fine.
 
Is there any way for me to get Zoho to simply pass the text in a URL field to the browser?
 
Any plans to support Javscript?
 
My ultimate goal is to create a clickable phone number, but Zoho seems hard-coded to Skype, which we're prohibited from using.
 
Thanks!
