ABSTRACT:
The invention relates to a method for the automatic configuration of an IP telephony device and/or data from a data transmission network with packet switching, which enables the device to obtain a lease on a virtual sub-network while it is physically connected to another virtual sub-network. In this way, for example, another device can share the same physical access port to the networks via a switch, without the two devices necessarily receiving a lease on the same sub-network.
