I am working on an IP Office 500 v2 8.1 (67) and just got call queuing setup. I have it setup with the calls coming into hunt group A with a single user assigned to it. The group overflows to group B with two users in it. If all three users (both groups) are on the phone, any new calls gets queued as expected. If the user in group A puts their current call on hold, the queued call rings on the next line. Is there some sort of "Calls on hold means busy" setting, or some timing setting I can adjust?
