Re: My FXO port is disconnection

I am assuming your FXO port is connected to the jack for a line from PSTN? You call that line and the caller hear a tone and disconnects? Can you describe the topology and relevent config?

Thanks for your replay.

My FXO ports are connected to PABX directly in extension ports, so when I call these extension's numbers I should give me the tone. In my case, I got this tone, but suddenly, it stops and gives busy

tone.

Thanks,

FXO port is supposed to give dialtone when it is called. You need to configure connection plar under the fxo port :

connection plar 1234

where 1234 is the number you want the call to go to.
