I dont think you answered my suggestion here:
Check Service Mode Ring Groups and remove 168 from any groups.
-In this case now make sure NO lines are programmed in Service Modes /Ringing Service/Sched:Night/Line Settings.
Check Sched:Evening Lunch etc
-H251 is probably a Hunt Group DN
Go into Hunt Groups and see what members and lines are assigned in the first few Hunt Groups.
-Again double check Prime Sets
Lines/001 is all you need to check for the PRI
The Lines 1 168 and all other target lines
Make sure Target Lines are set to None for now.
-What is the version of the KSU (or SP CODE in Maintenance)
-What is the voice mail version (or press 9 once logged into 983)
