Hi,
It should be ok, but in your case the TH will not benefit from the
dialog module (you do not use it) - all the info to he hidden will be
appended to the Contact hdr (as extra param), while when using the
dialog support, this info is stored into the dialog.
To be honest, I never tried the combination of nathelper and TH
_without_ dialog support. But give it a try...if you get a trace, I can
check if ok.

Thanks Bogdan, Well, I have fix_nated_contact() at the very top of my
script :
route{
force_rport();
if (nat_uac_test("23")) {
fix_nated_contact();
setflag(NAT);
}
if (!mf_process_maxfwd_header("10")) {
sl_send_reply("483","Too Many Hops");
exit;
}
....
....
if (has_totag()) {
# sequential request withing a dialog should
# take the path determined by record-routing
#### remplazar : if (loose_route()) {
if (topology_hiding_match()) {
...
...
*## esconder topologia antes de pasar la llamada*
topology_hiding("UC");
route(RELAY);
}
so is my script correct ?
I just want to make sure I have a correct script before I do any
further work on this.
Thanks.

Hi,
You can do TH with nathelper, BUT be sure to create the dialog +
TH AFTER doing the fix_nated_contact().

We used instruction in the book, which states at the end of the
paragraph this :
Topology hiding limitations
You cannot easily combine topology hiding with NAT traversal
because both the
processes mangle the Contact header. Topology hiding will not
hide the address and
other information contained in other headers such as the display
in the From header.
To change the From header, you can use the uac_replace_from()
function.
I think our problem comes from the fact that we are using
nathelper and also an rtpproxy in our script.
can anyone provide help about activating topology hiding along
with nathelper ?
thanks in advance.

Hello grupo,
We have configured topology hiding in opensips 2.2 this
way :
please confirm to us this is the only thing we need to do
or is there anything else that needs to be added.
route {
....
....
if (has_totag()) { # sequential request withing a
dialog should # take the path determined by
record-routing #### remplazar : if (loose_route()) { if
(topology_hiding_match()) { ...
...
*## esconder topologia antes de pasar la llamada*
topology_hiding("UC"); route(RELAY);}
also what could be a quick test to see if this hiding is
working or not.
thanks in advance.
Alberto
