I made a prepaid call system and applied sched_hangup in dialplan to limit the call duration like(lua) :

Recently I updated my system to allow user buy points during calling, but when I tried to recall sched_hangup like [sched_hangup +30 <uuid>] in fs_cli it still hangup at 60s (which hopes to hangup at 90s).

Is there any mistake in my usage? Or any solutions for this?

Regards.
