Re: Re: [Users] 200OK Contact header field.

[Maciek Kowalski]

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 at 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.

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).
