<p>The method controls the transmission path of packets of data in a message transmission between a first and at least one further subscriber of an IP Centrex group in a first communication network. A network limiting module (5) is provided which is connected, via a transmission channel, to a second communication network in which a network element (7) provides Centrex service and performance characteristics for the group. In the network limiting module, under the control of signalling information provided from an address translation function, the data packets received by one subscriber ae deflected back to the first communication network. Independent claims also cover a communication network and network limiting module.</p> |
