Abstract

A method of establishing a voice/data call between at least two subscribers is disclosed. Prior to the establishment of the connection between subscriber 1 and subscriber 2 via exchanges, a first time window is inserted in which subscriber 1 requests specific execution of the call to be established.

Claims

1. A method of establishing at least one of voice and data call over a channel which interconnects at least two subscribers via at least one exchange, wherein after requesting a call to be established between subscriber 1 and subscriber 2, said request comprising entry by subscriber 1 of a call address of subscriber 2, and prior to establishing a connection between subscriber 1 and subscriber 2, a first time window is inserted in which subscriber 1 is given an option to request specific execution of the call to be established, and, if subscriber 1, before closure of the window, does not request any specific execution of the call, the call is established with a standard call setup.

2. A method of establishing at least one of voice and data call as claimed in claim 1, characterized in that within the first time window, a signal is sent from subscriber 1 to an exchange, and that after recognition of the signal at the exchange, a second time window is opened.

3. A method of establishing at least one of voice and data call as claimed in claim 2, characterized in that within the second time window, specific further signal sequences can generated by subscriber 1 which are recognized at the exchange and result in dispatching the call to dedicated servers dealing with a specific execution of the call.

4. A method of establishing at least one of voice and data call as claimed in claim 1, characterized in that the first time window is opened for a limited period of time.

5. A method of establishing at least one of voice and data call as claimed in claim 1 characterized in that the second time window exists for a defined period of time beyond or until termination of the specific signal sequence as communicated by subscriber 1.

6. A method of establishing at least one of voice and data call as claimed in claim 1, characterized in that without signaling by subscriber 1 to request for specific execution of the call, standard call setup is executed.

7. A method of establishing at least one of voice and data call as claimed in claim 1, wherein said first time window is inserted after generating a ringing tone for subscriber 1 and prior to generating a ringing current for subscriber 2.
