Information required for routing between IP Telephony Administration Domains (ITADs) 11,14 is gathered automatically by a location server 17 which operates in the listen-only, uni-directional, mode and which is peered with a Telephony Routing over IP (TRIP) inter-domain protocol. The peered location server uses the TRIP protocol to discover routing information thereby allowing for the automatic updating of route data for both internal and external telephony routes. In one embodiment, the peered router maintains an up-to-date picture of the service provider's routing and time stamps the collected data, thereby allowing for the collection and utilisation of historical TRIP performance information. Based on such historical analysis, the service provider can keep track of, for example, its most reliable peers, peering routes, unstable routes, unavailable routes etc.
