Hi Rodrigo,
I feel there might be a confusion somewhere here. what is behind the NAT
? your opensips ? or the end point ?

Hi Bogdan.
Thank you very much for the hint! I got more another explanations here
too and I was able to conclude the following:
To be sure the traffic sent out by opensips has the public IP and not
the local private one, I will set a stun server in the softphone
behind the NAT. In this case, such softphone will send SIP messages
(that has Contact header field) already considering the public IP. I
guess this solution will be enough for my case.
I can't set advertise_address and advertise_port, because my project
will have lots of copies, to be installed in lots of homes. In every
home, there will be a different public IP (and another private too).
Today I will configure a NAT device, put it in my network, bind the
proxy and sofphone to behind it and execute some tests.
Best regards.

Hi Rodrigo,
If opensips is behind NAT, you should not use the nat related modules
(as the incoming traffic is correct from nat perspective, as
originating from public network). What you need to do is to be sure
the traffic sent out by opensips has the public IP and not the local
private one. For this, look at :
advertise_address
advertise_port
(http://www.opensips.org/Documentation/Script-CoreParameters-2-1#toc25)
<http://www.opensips.org/Documentation/Script-CoreParameters-2-1#toc25>
openSIPS | Documentation / Core Parameters - 2.1
<http://www.opensips.org/Documentation/Script-CoreParameters-2-1#toc25>
www.opensips.org
This section lists the all the parameters exported by OpenSIPS core
for script usage (to be used in opensips.cfg) This document is for
OpenSIPS 1.12.x
And be sure you have do port fwd of the SIP port from the public
address of the NAT to the private IP of your opensips.

Hi.
I have read the entire OpenSIPS' documentation about how to deal with
NATs.
I found ways of dealing with messages from client that is behind NAT.
OpenSIPS can fix Contact headers fields and registers, when SIP
messages comes from clients and cross NATs before reaching this proxy.
However, my OpenSIPS and callee is behind NAT, not the client. That
is, if a client (caller) calls the callee, how could OpenSIPS with
its functions fixes Contact header fields in responses that go from
callee to caller, so that the client will be able to send ACKs? It is
still obscure to me.
Any idea?
Best regards.
