Reduce Inactivetimer QCI1 in VoLTE

Hi Experts.
If VoLTE eNB norm release is less as compared to eNB abnormal release, can inactivetimer QCI1 be reduced?

The cause code is s1 fail, obviously it has to be solved.
But no abnormal MME release seen.
eNB release is S1link fail.

Please check what is “trace event id” for that release. Maybe get some clues.

S1 link faults.
