The Greek eΚΛΗΣΗ project is now in the final stages of creating an automatic warning system in case of a traffic accident. The first tests of the automatic emergency call system (eCall), within the frame of the pilot national research project eΚΛΗΣΗ (http://www.ecall-hellas.eu/), have been successfully concluded. The tests were performed on a prototype system and rooted emergency calls from the In Vehicle System (IVS), which was implemented by the Institute of Communication and Computer Systems (ICCS), an ERTICO partner, to the Public Safety Answering Point (PSAP), which was implemented by SPACE HELLAS, through the mobile telecommunication network of COSMOTE. The national project eΚΛΗΣΗ prepares Greece for the implementation of the eCall service which will be obligatory for all EU member-states from end 2014.
