ABSTRACT:
The present invention relates to a telephone system, an exchange and a method for setting up telephone connections between a computer, which is an extension of the exchange, and the exchange via a computer network. The exchange comprises a switch core, a switch control means for setting up connections and a network connection device connected between the switch core and the computer network. The computer comprises a function for use as a telephone and has a computer network address. The network connection device registers the computer as a telephone to which calls can be made in the switch control means, sets up at least one traffic channel via the computer network for sending speech signals, and, receives data packets containing telephony from the computer over the traffic channel and removes a signal structure suitable for telephony from the data packets. The switch control means allocates a telephone number to the computer.
