This is a quick fix for the TEL attacks described here [2].

TelStop publishes a TEL handler and will be invoked on every phone call the originates from a TEL URL. TelStop will only show itself if it sees a problem with the URL. You will only see the WARNING screen if the URL looks fishy.

After installing try the TelStop Test Page [1]

    Light weight, non-intrusive, reliable. Not sure why this functionality isn't built into the OS.

    I would like to put this on the SD card instead of using phone memory.

    It works. That is what is important. Protecting our investment & our contacts. Many thanks.

    It just works. Test it with the link on the description page and make it the default dialer. You won't see it again unless you stumble onto a malicious link.
