Hi folks. I'm relatively new to this product and have been learning it as I go. The issue I'm having is that the overflow does not appear to be triggering.

During a test, the hunt group kept ringing well past the time it was supposed to release to the overflow extension.

Running an MP5000 System, Release 220.11, Feature set 2.0, Network version 550

In VMMI, station hunting, it's set up with the following:
overflow extension: 1100 (the operator)
Hunt group members: about 10 entries
Name: Appoint
Full Name: blank
Search Type: Ring All
Call Advance Time: 20 sec
Overflow Time: 2 min
Recall Time: 2 min
Queue ringing calls: yes
incoming digits display: yes (though not working either it seems)
Multiple Call: no
Use Pilot number as voice mail id: no
All other options: none

Any idea what is holding it up?

Try setting your recall time longer or your overflow time shorter
