[Asterisk-Users] FXO no release useing fxsks & disconnect supervision from telco

[steve casto]

Adtran 750
d4,ami
loop start
fxs 5x4 port
fxo 1x4 port
TE405P
Asterisk 1.0.9 stable
span 1 -> CAC channel bank all FXS
sand 2 -> Adtran 750 20 FXS 4 FXO (new FXO card)
span 3&4 -> outgoing only E&M

A call comes in from the telco on the FXO port & answered on a FXS 
(fxoks). If the FXS hangs up, ok, if the FXO (fxsks) hangs up first:
1) CPC is receive at the FXO (an open from telco)
2) the A bit for the FXO port -> 0
3) FXS port get short reorder then Asterisk dial tone
4) the FXO port is not dropped by Asterisk
5) telco recording like 'Please hang up to make a call' no busy then 
dead air (on the telco line connected to the FXO)
6) to reset,the FXO port needs to be opened at the telco demark > 3 sec. 
opened less then 3 sec. the FXO port is still in an off hook & draws 
dial tone from the telco & does not drop
This happens every time. Being that that the FXS, still off hook when 
the FXO hangs up, drops that connection to that FXO, Asterisk must know 
the FXO has hung up but Asterisk does not release the FXO.
