I had a fun one yesterday: I could not delete a user, the error would says "multi-line set" or something like that.

The problem was that the user was a set supervisor for a HUNT GROUP. Apparently, you cannot be a set supervisor for a hunt group (which sounds normal to me, what about you?), but the PBX let the customer did it. Anyway.

More detail: User 3000, set supervision for 4000.
4000 is a hunt group with 3 sets inside.

The solution was to :
- delete the hunt group 4000,
- create a user 4000,
- delete user 3000,
- delete user 4000,
- recreate hunt group 4000..
I don't know how they though about this (TAC) but they are definitly good, and I am learning a lot everyday
