I am running into a problem with one of my sites. People place calls into our main number and the AA answers. I have noticed if someone hangs up while it is playing it will leave the FXO port connected for several mins. I verified this by placing a call into the main number and then disconnecting. On the router i issued a sh voice call sum and port 0/0/2 is still open several mins after I disconnected. Now if I place another call it rolls over to the other line we have and the same issue happens. At that point I can no long call into the system. After it times out or disconnects(Not sure) it works fine.
Now I know with IPCC i can do an on exception cisco contact disconnect and send it to end. If this the same issue I am running into and if so how do i correct it.
