1. A method for setting up a telecommunication connection via a public telecommunication network from a first telecommunication terminal station which is external to a private branch exchange, referred to as a PBX, which method comprises the steps of:
- setting up a first connection between the first terminal station and the PBX;
during this first connection, transmitting information over the connection to the PBX;
determining whether the information contains predetermined data including a calling number for a second terminal station;
before attempting to call said second terminal station, terminating the first connection;
the PBX setting up a second connection to said second terminal station whose calling number was included in the information;
the PBX setting up a further connection to the first terminal station;

Abstract
Method for establishing a telecommunication connection wherein a calling party at a first telecommunication terminal station external to a private branch exchange (PBX) sets up a first connection to the PBX via a public telecommunication network and transmits information to the PBX which indicates, inter alia, a telephone number of a second telecommunication terminal station. In response, the PBX sets up a telecommunication connection between the first telecommunication terminal station and the second terminal station and, in addition, the PBX stores information relating to call charges resulting from the connection to the second terminal station.
