OK so here's the latest. I called each trunk individually and hung up while voice mail was talking. The first six lines disconnected within 6 seconds of me hanging up. The last two lines went about 30 seconds before releasing. The only thing that I found different in programing is the last two lines each have a line voice mail ID. All lines have disconnect supervision set to yes. Still not sure what to make of it.

I still think this is a disconnect supervision issue, maybe specifically on those last 2 trunks.
What version of voicemail are you using?
Another way to test your disconnect supervision is to abandon a call while on hold. Not exactly the same, but should tell you if you're getting the disconnect from the carrier.
I also suspect another option as there may be something off with your seconds of silence/non-silence and minimum message length settings. What are those set to?

My seconds of silence/non-silence are both set to 4.
Disconnect supervision is set to yes on all 8 lines. I don't think this has anything to do with it, but, disconnect notification is set to no for all stations. Even voice mail. Is this right?

My voice mail version is 8.5 I called the last two lines from my cell phone and then placed the lines on hold. Line 7 held on for about 30 seconds before releasing. Line 8 held on for about 15 seconds before releasing. I called it back again and this time it took 30 seconds before releasing. Does this help?

I had one of these very similar problem several years ago. It was a DX80 w/VM, but same problem. 2 of the lines disconnected the way they should, but 2 wouldn't disconnect reliably.
Went through all the possible scenarios, calling the line, getting put on hold, then hanging up from the distant end, system would either take forever to release or wouldn't release at all.
Called the CO to verify that CO disconnect was on the lines. They told me it was. Turned out that 2 of the lines were served by one switch and the other 2 were served by a different switch. Each switches timings were different. I could make the symptoms reverse lines by changing the timing in the DX80. Took some doing, but since I personally know the guys running the switch, I got them to put all the lines into the same switch to get the same timings, voila problem disappeared.
You may be up against a similar problem, and with an FXII, you can set each line different (50 or 300 ms) CO disconnect times. Might be worth a shot.

Check your settings on the C.O. ports, as Russ suggested. Also, check what your minimum message length is set to.
DO NOT touch the Disconnect Notification setting. This bit me one time, and never again. It's my understanding that is was there only for use with Comdial's proprietary Air Impact wireless phones (not the Scout or Scout II), and should not be used for anything else. Make sure this setting remains disabled. This would be a station setting, not a C.O. port setting. The C.O. port setting (Disconnect Supervision) should remain turned on, as you indicated it was.
