That problem goes by many names: tromboning, hairpinning, etc. There are several signalling methods, depending on what protocol is spoken by the remote switch: * q.sig has (can have) support for this * Explicit Call Transfer (ECT), used on EuroISDN I think) * 2B Channel Transfer, on 5ESS switches I don't think these are signalled the same way.
