Hi guys,

I have issue with calls come thru FXO to IP extension they can hear me but i couldn't also when i try to use FXO to make a call i can't hear him but he can hear me but when i make a VOIP call it seems good and also when i received call from DID Number to my IP extension it seems good.

Is there any configuration i have to do it .

Is that IP extension connected to the Quadro LAN, and is in the same subnet as Quadro?
Or that is located somehwre outside, and possibly behind a NAT?

Can you also make an FXS to IP extension call and see if audio behaves the same way?
