Tallinn International Airport in Estonia, a state in the Baltic region of Northern Europe, is one of 10 locations testing the Skype Station, developed by AdTech, to allow users to make free video calls.

Skype Stations can be deployed in a variety of places, including malls, hotels and airports.

The stations are easy to use, prompting callers to log into their Skype accounts when they enter the booths.

Although the machines come standard as silver, deployers can order them in nearly any color and can request branding.
