Thanks for a quick response.
I'm sorry but I've messed up a little bit.
I've got 2 asterisks and the one I've mentioned is on the same box as
Openser.(Openser 192.168.1.2:5060, Asterisk 192.168.1.2:5065)
Openser acually "record_route" the Invite but it puts there his private address
(192.168.1.2). I presume that's why the user behind different NAT cannot reach it.
I've tried record_route_preset(""); with public IP of NAT where openser is,
and in that configuration, ACK reaches Openser but it loops and is not forwarded to
192.168.1.2:5065 (Asterisk).RURI in this ACK is "sth@192.168.1.2:5065", and
Openser listens on port 5060 so I dont understand why it behaves this way.
What do You suggest?
Thanks in advance and sorry once more for this mess.I hope what I write is still clear.

Temat: Re: [Users] 200OK Contact header field.
You are right. If record_route is used the ACK should
be sent to openser
first. Thus, inspect the 200 ok received by the client if the record
route header present, and inspect the ACK sent from the client if a
Route header with the content of the record_route header is present.
btw: which client do you use? There are dozens of buggy sip clients out
there.

works great till asterisk answers with 200OK. In this message the Contact header field is
set to "192.168.1.5:5060". When user recieves this 200OK it sends ACK to
IPaddress 192.168.1.5 (and since he is behind different NAT..the message goes nowhere).

I thought that the ACK should first go through Openser.
