Has anyone ever tried to integrate a Norstar 0X32, 7.1 Software with an Octel OV250 via inband using DMI-4 units?

we have used the DMI-4 to integrate a nortel MICS with an amanda. It is miserable. It goies back a couple of years now, but the biggest issue we ran into was that the DMI's would auto re-load the name/number table, but when it did it would miss an extenion or two and then they would call freaking out that the system was broken. We ended up turning off the auto part, but it is still a half-ass solution. I would highly recommend putting in a call pilot.
