Problem with analog lines not hanging up

Hello,

I have an issue with my Asterisk box not hanging up channels after a 
call is completed.   We have had several times where a call comes in on 
one analog port, gets forwarded back out through the second analog port, 
and then when it doesn't hang up correctly, both analog ports are 
showing as up, but there is no traffic.  Reloading asterisk causes our 
SIP phones to ring constantly, because the channels look like they are 
up, but when we answer all we get is a fast busy signal.  The only way 
to clear the condition is to reboot the asterisk box.

The * box has three FXO single port adapter cards in it. two going to 
the phone company and the third going to a Packet8 phone.  We don't seem 
to have as many problems with the Packet8 phone.  I am not sure of the 
brand on the cards, just that they are not Digium.  I am hoping that 
there is a setting in the zapata or asterisk configuration that can be 
adjusted to make sure that the channels are hanging up correctly.

Any ideas?
