Incoming calls keep busy (doesnt hang) - GXW410X PSTN Gateway

Hi.

I have a problem with GXW410X PSTN Gateway and Asterisk 13.22.0.
Now the gateway have 6 analogic lines connected to fx ports, these are the configs, the lines are routed to a preatender in asterisk.

I have read about the Call Progress Tones, but it doesnt work.

Thanks

I have that same devices working on my house, check your device configuration
