[OpenSIPS-Users] opensips+asterisk: signalling not working?

Hi,

> Make a sip trace on your asterisk box to see where the ACK is sent. Maybe you need to enable nat on asterisk to force it to send the ACK to the originating IP and not the IP of the contact field. Have a look at http://www.voip-info.org/wiki/view/Asterisk+sip+nat

now I have nat=yes ;
in the asterisk documentation I read that with nat=yes asterisk
replies directly to the source IP address, ignoring SIP headers.
So, now I assume this is wrong, because the source ip is opensips.
But I can't understand if I must use no, never or route.

thanks so much,
