GrandStream HandyTone 386 with PSTN fax machine connected

[rdevrede]

Hi. Because the Auto Attendant and Zoiper solutions do not working we bought a GrandStream HandyTone 386 and connected the PSTN Fax Machine to FXS port 1 of the handytone.

 

The extension does it registering well via the HandyTone.

 

I created a sip trunk which is directed to this extension.

 

When I call the number it's well directed to the handytone and the fax machine rings and pick up the call. I hear a fax signal.

 

But that's it. No fax is being received.

 

What should I setup into the HandyTone? I see a lot of settings like : Onhook Threshold Hookflash OFF 600 ms 800 ms 1000 ms 1200 ms

and FXS Impedance.

 

What should I choose. Does anyone have this working in The Netherlands? (Europe?)
