Abstract
In a communication network, a first terminal is arranged for communication with a second terminal via a packet switched network. The first terminal is connected via a first gateway to the packet switched network, and the second terminal is connected via a second gateway to the packet switched network. If the second gateway is connected via a dial up connection over a public telephone network, the second gateway (24) may not be connected to the packet switched network resulting in a failure when the second terminal attempts to contact the second terminal via the packet switched network. To avoid this situation, the first gateway is arranged for dialing the second gateway directly via the public telephone network and requesting that the second gateway connect to the packet switched network. After the second gateway connects to the packet switched network, the first terminal can connect the second terminal via the packet switched network.
