Abstract
1. Method for the forwarding of emergency calls from persons requiring assistance, in wich method an emergency call subscriber set, which is connected to a subscriber line of an automatic telephone exchange network, after actuation of a sensor automatically selects the call number of an emergency call exchange connected to the automatic telephone exchange network and after the thus effected build-up of a telephone connection gives out an identification and an alternate speech direction equipment in the emergency call subscriber set is subsequently switched to become effective through a control signal of the emergency call exchange, wherein its speech direction can be switched over through tone frequency switch-over control signals sent from the emergency call exchange, characterised thereby, that the identification is sent as continuous signal with the tone frequency or tone frequency combination differing from emergency call subscriber set to emergency call subscriber set until the alternate speech direction equipment is switched to become effective, that the alternate speech direction equipment is switched to become effective through the switch-over control signal first sent, that the alternate speech direction equipment is switched during the reception of the switch-over control signal to one of the possible speech directions and during the non-reception to the other speech direction, wherein a fixed association is predetermined, and that the release of the telephone connection is effected through a release command transmitted from the emergency call exchange to the emergency call subscriber set, wherein the emergency call subscriber set is set into the rest state through this release command.
