yeah I understand that, so what happens currently is reception forward calls to one number, and several other staff phones all ring simultaneously and they have the ability to answer that call. Adding extra staff to that pool doesn't seem to work.
I can see the staff are in the pickup group so assumed this is where i'd add the new additions. I'm sure I'm missing something but I've been hunting through menus all morning!
Edit: I was under users and devices-group programming-pickup groups, selected group, added member via their number
