“Ok, just to confirm .. the HLR may know that the MS is not active in any VLR and would pass this info to the GMSC which may:
1. Forward the call if CF is active for that subscriber OR
2. Signal back to the originating exchange that the MS can not be reached (not sure how this happens though)
Can I safely assume that in the above case an IAM is not sent to the VMSC? ”
With Reference to above :-
1.Yes an anothe Callsetup with IAM will bestarted.
2.GMSC Gtes the ABSENT Inf in “ROUTING ENQUIRY Response ” so it drops the call to announcement.
