In Europe, we first can find some vocal services managed by private companies such as Messenger Service. ITT Commercial Cables and One Voice in G.B., or Teletam and Tei£services in France, or even Voicemail Svenska in Sweden. They are using various systems (VMI, IBM, FERRANTI, VMX) and generally have about some hundreds customers each.

But at the present time a major fact occurs that requires all our attention: The crystallization of the vocal public services run by P.T.T.'s. Voice mail services proposed by P.T.T.'s and their subsidiaries are in Europe an outstanding set of homogeneous services, due to the common origin of equipments and the frequent meetings of the teams. We are in presence of a rather exceptional situation which should attract the attention of C.E.E. authorities as well as multinational companies, but also firms that have just to choose for services or equipments.
