Abstract
A SCP connected to a switch through an ISUP loop-back trunk redirects a dialed call to an intermediate destination. After the intermediate destination releases the call, all circuit segments from the intermediate destination back through and including the inbound (to the MSC) side of the loop-back trunk are cleared. The SCP then establishes a connection through the inbound leg of the loop-back trunk to the dialed destination. The SCP remains in the circuit for the duration, including all intermediate call completions as well as the call to the dialed destination. When the call to the dialed destination is complete, the entire connection is released per standard ISUP procedures.
