Summary:A method for setting up a call to a subscriber station. The method comprises, at a first telecommunications platform, receiving a first request to set up a call to a subscriber station. The first request is processed at a second telecommunications platform. The second platform provides a second request to set up the call to the subscriber station, where the second request includes a non-loop parameter. The second request is received at the first platform and the first platform responsively sends a service request including the non-loop parameter to a third telecommunications platform. The third platform detects the non-loop parameter and, in response to at least the non-loop parameter, directs the first platform to set up the call to the subscriber station.
