PSTN not hanging up.

I have an OpenVox 400 card with two FXO modules. I live in Idaho and use Frontier Communications. I can make calls out just fine, but when I recieve call, if the outside caller hangs up, the connection does not disconnect. I'm hoping this is another quick fix. I've gone through a couple how to's but again, none of them seem valid for this version of trixBox (Ver 2.6.2).

Thanks,

try to modify indications.conf set country to your country, and open callprogress/busydetect/busycount in zapata.conf,
