FXO port stays off-hook after call is ended from the PSTN

Hi,

I have this scenario where I have a cucm 7.0.1 and a 2811 h.323 gateway and have a fxo port connected to PSTN. I used the command "connection plar opx" on my voice-port so that when I call from the PSTN going to my fxo port in my 2811 isr router, one ip phone will ring. Fortunately it does ring, but when I end the call from my calling number (from the pstn) the ip phone stays off-hook, the fxo port still has light, and the ip phone just change in busy tone but the call is not ended.

What and Where am I doing wrong? Am I lacking some commands on the h.323 (2811) side or on the CUCM 7.01 side? What command or settings must I issue so that my ip phone will go on-hook when I go on-hook from the PSTN?

Just an added information that when I call from the PSTN to my ip phone connected to the fxo port and then hang-up, the fxo port still has light in it and the ip phone still rings until the T301 timer on the CUCM is reached.

What command/settings am I missing? Thanks!
