I have a Premier ESP, works great, just got my station b card in a few days ago, rigged me up a ring generator. On the station ports I have four ports pluged into the voice mail computer. Now just one problem, when the voice mail picks up and answers, does everything just like it should except the fact it don't hang up. And when it don't hang up, I get this stupid system alarm #1 (saying the phone is offhook).
I can plug the voice mail directly into the phone line and it works just fine. But through the system, it won't hang up.

Now through the system, when the CO is cut off, the station b extention goes to an internal dialtone.

Any suggestion on how to fix?
