Logoff/Detach while Registered to a Backup LIM

If an IP- or CXN-extension user logs off while being registered to a backup HLR, that will basically be a normal logoff/detach. However, if it was the last or only extension that logged off, the temporary HLR is removed. The server (the LIM with temporary HLR) will inform all other accessible LIMs that the active HLR is now the ordinary HLR, even though the ordinary HLR server is probably still not accessible.
