meta tag format detection telephone no does not work

Hello,

I'm writing a web-application for my Ipad and all works fine. The only problemI have, I use <a tags wirht references to other pages. To avoid menu bar, I use the onclick with window refresh to go to the link This is used in <a tag with text like 91 92 00 .. and so on. My problem is, that some of this texts are recogniced as phone numbers and not as normal links. I added the meta-tag for disabling the phone numbers to the startup page and to the problem pages, it seems not to work. When I hide the 93 with a .93 then it works. What can I do, to make the meta tag work or to make my links like 20 work?
