# symbol in tel: links not working on nokia devices

I have a html page with links like < a href="tel:*123#">*123#< /a>.开发者_如何学C

when user clicks on the link from a nokia device (tested with N73, E72) it says 'invalid phone number'. I have found that numbers without the # symbol are dialed out fine.

Just wondering if there's a specific reason for this restriction and is there a way to encode those numbers so that they work from nokia devices.
