I'm not sure what you mean by "set the ext to UCD group membership of that UCD group". I tried putting the IVR exts in a UCD group and it works OK (DIL to UCD). It wouldnt work to put the regular phones in the UCD group or am I missing something here? When I tried a UCD group I couldnt figure out how to get a UCD IVR ext to forward if it was RNA. UCD only hunts on busy. I played with that a LONG time and couldnt get what I wanted. However, now I may go back to that and give up on hunting for RNA. The customer wanted overflow to a ring group if an IVR ext was RNA (ie a bad IVR port). This sounds confusing, thanks for trying to follow it!
