That was my first plan, using 2 groups, but we have 50 already.
its a brand new install (Literally it is going in as I type this!) we don't have the ps-1 modul/unit.
I've played with the audio settings and I can get ringing or music on hold, can't get both to work. (I may be doing it wrong)
Hmm ok, back to the drawing board!
Thanks
