Hello All.
If Invite is send at MO;
but MT registration going on;
and setup fail with 487 in good RF.
Can this be IMS issue?
Does the fail occur contionusly or only one time?
Sometimes randomly.
May be 2-3 percent of drive.
2-3 percent of short calls.
Too high.
Good to be check at IMS side, why registration takes too long and not completed on time.
