I have a customer that when you call in and voice mail picks up it takes forever for the call to disconnect. I've looked in system integration, but is there any other section that I might need to look at?

CO disconnect is programmed primarily in the Class 1 setting for the trunks. The word 'DIS' will show up for a trunk programmed for disconnect protection. The KSU has to detect the disconnect before it can send the signal to the voice mail.

This is assuming the CO is SENDING the disconnect signal.

An easy test is to call in, answer the phone and pull the bridge clip for the trunk. If the light on the phone's line button goes out right away, the KSU is detecting disconnect.

To test whether the phone company is sending the signal ,call someone using one of the system's lines. Tell whomever you call that, once YOU put them on hold, to count to ten and hang up. Once you put them on hold, count to ten and watch the line button. If the the light takes longer than a ten count to go out, like say a count of 30, you're not getting disconnect from the phone company and will have to get them to turn it on.

What happens a lot is, the customer gets a phone system, but doesn't tell the phone company. In my area, if you do not tell the phone company there is a switch onsite, they don't turn on disconnect supervision.

In my area, even if you tell the phone company you are installing a phone system, it's hit or miss on getting disconnect supervision! Many times it comes down to finding someone that even KNOWS what I'm talking about. *sigh*

This is an issue I deal with a LOT! I've had Verizon insist they had disconnect on, and not, many times. Once I went out to a school 4 times, each time Verizon told the school they had turned it on, but, each time I found they had not. Not sure if I can say the name on this thread, but, a popular telecom tools dealer online sells a dsconnect tester which comes in handy to prove to clients that the disconnect is not there. Having the client threaten the phone company with sending them the bill for service calls often speeds things up.

Iwatsu claims the 4TRAN Card won't help, but, I've made a habit of installing it in schools, and gotten rid of that problem. It's not that expensive, and monitors for silence to drop calls more efficiently.
