The present invention relates to a method for routing calls from a terminal in a first telecommunication network, for example an intranet, to any terminal in an external telecommunication network, the interworking between said networks taking place through one of several interworking units or so-called gateways (GW), and in order to provide a method which in a more effective manner can optimise such interworking between such networks, it is according to the present invention suggested that there is used at least one routing entity which routes the call or calls through a gateway (GW1, GW2) giving the most optimal route, for example the most cost effective or resource effective route.
