Rodrigo,
In OpenSIPS you have 2 type of NAT modules:
- for NAT detection, mangling SIP signaling and for doing the NAT
keepalive: you have here the NAT_traversal and nathelper, 2 similar
modules as capabilities;
- for media relay - modules that interact with an external media relay
for RTP; and here you have again 2 modules, the mediaproxy and rtpproxy.

Hi Bogdan,
Thank you. Very well remembered!
Let me ask you conceptual question, please:
When should I use MediaProxy, not being necessary to use NAT_TRAVERSAL
and NATHELPER?
When should I use NAT_TRAVERSAL, no being necessary to use MediaProxy
and NATHELPER?
When should I use NATHELPER, not being necesary to use MediaProxy and
NAT_TRAVERSAL?
When should I use some kind of mix of these 3?
Best regards.

*Assunto:* Re: [OpenSIPS-Users] Minimal example of NAT traversing. How
could it be done? No need for MediaProxy at first glance.
Hi Rodrigo,
User "make menuconfig" in order to auto-generate scripts - the
residential script has an options for NAT support.

Dear OpenSIPS-users,
I'm studying about NAT traversal with OpenSIPS, since last week. I
also have found the documentation about the software MediaProxy (in
http://mediaproxy.ag-projects.com/).
As long as I'm still getting 'kind of first steps' knowledge base
about NAT traversal, I'm not interested, at least for a while,
in MediaProxy software functionalities.
By the way, as a first contact with the NAT traversal mechanism,
I just would like to let the INVITE from a caller reaches the callee,
with caller behind a NAT. For this purpose I have 2 questions:
a) Am I free of using a kind of mediaproxy software, whether I want
to build a prototype schema that will just creates and sends an
simple INVITE, from caller behind a NAT, to a callee? That is, if I
want just to run a simple test of NAT traversal, I don't have to
worry about mediaproxies, have I?
b) How could be an example of a simplest script code for that,
considering that there is only one proxy for all peers and all of it
is registered in such proxy using the same domain?
Any hint will be very helpful!!
Thanks a lot.
