Hotline: 118 118 installs phones in liveried taxis

The telephone directory service 118 118 has installed phones in liveried taxis across London to promote its question-answering service.

Passengers can call 118 118's "Ask Us Anything" service free of charge from the phones, as part of the campaign with Clear Channel's Taxi Media division. It was planned by Posterscope and OMD.
