TelStop

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]
