Thank you to
5Etek-mike for getting the thread back on track. The queueing thing is apparently important, and the Magix does have some fine queueing capabilities.
I can set three levels of alarms (based on the number of calls in queue); I can play music or messages for those waiting and provide a "#" opt-out for anyone who would rather leave a voicemail than wait further.
Group Supervisor phones--properly defined in "operator positions"--have the ability to monitor exactly who is logged into the queue and who isn't via button LEDs. That piece comes in handy when you have individuals who pretend to take calls while talking to their friends instead.
The key limitation rears it's head when you try to add a queue member that is not local. With a networked Magix (and I don't know if this applies to BrianS) the limitation is 20 local members and ONE remote member. Yep...that's the big ouch. And that limitation isn't anywhere on the IP Office radar.
