I took a new gig a few months ago an inherited a system with 100 hunt groups that don't have a COS assigned, and I need to assign one in order to make them resilient (why they weren't set up resilient on install, who knows). Most of the hunt groups either have no members (point to an auto attendant) or have non-prime Key System lines as members. I know if a hunt group has no COS defined, it will inherit the COS of the first member, but what COS is assigned if there are no members or the members are non-prime lines? Does it inherit COS 1 then? I can't remember and this isn't worth opening a ticket with my support partner to find out.
