Hi Nitesh,
Be sure all the remove_hf() are on the right execution path and BEFORE
the t_relay() for the sequential requests.

Bogdan,
Thanks for your feedback.
After reading the docs and following this tutorial
(https://opensips.org/Documentation/Tutorials-Topology-Hiding
<https://opensips.org/Documentation/Tutorials-Topology-Hiding>) I
finally got it working. Thank you!
INVITE is clean, topology is hidden and ACK is sent back and forth.
Calls are holding good.
While confirming each ACK and BYE, I noticed Originator's User-Agent
is passed on again only on to ACK and BYE.
I tried to define under:
route{
if (has_totag()) {
if ( is_method("ACK") ) {
if(remove_hf("User-Agent")){
xlog("*** has-totag -> ACK
User-Agent found and removed on $rm from $si (callid=$ci). ***\n");
}
}
if (is_method("BYE")) {
xlog("*** if is_method(BYE) on $rm from $si (callid=$ci)
***\n");
if(remove_hf("User-Agent")){
xlog("*** is_method BYE User-Agent found and removed
on $rm from $si (callid=$ci). ***\n");
}
# do accounting even if the transaction fails
do_accounting("db","failed");
}
}
}
But still Originator's User-Agent is passed on to ACK and BYE...
Ignore the xlog(""), it is just my way of learning what each line is
doing and if getting executed :-).
Any suggestions?
Cheers,
Nitesh

Hi Nitesh,
Where you have the loose_route() in your script right now, use
topology_hiding_match()

Hey Bogdan-Andrei,
Thanks for your feedback.
To be honest - I don't know!
I followed some online tutorials and tried to implement
"topology_hiding()" after is_method("INVITE") since the first
message sent to Outbound Provider is INVITE.
I never tried topology_hiding_match().
What is the right way to implement topology_hiding module? My
scenario is simple, I'm using the default cfg and making ATA
register to OpenSIPS to make Outbound PSTN calls.
I guess Bootcamp is the answer :-)
Cheers,
Nitesh

Hi Nitesh,
Do you do topology_hiding_match() for the sequential requests
(instead of the typical loose_route()) ? As it seems you cfg
fails to properly handle the in-dialog / sequential requests.

Hello All,
I don't know if this is by design or me not implementing
correctly! I'm a newbie to OpenSIPS...
So I generated a new opensips_residential.cfg file and only
edited it with topology_hiding("UC"); under INVITE. Plus all
the extras to make ATA register successfully and SIP trunk.
Every time I make a call two INVITE dialogs are created. One
from ATA to OpenSIPS and second one from OpenSIPS to
Outbound Provider. When a PSTN call is answered, the
Outbound Provider sends 200 OK back to OpenSIPS, and
OpenSIPS sends back 200 OK to ATA. Then ATA acknowledges
with ACK back to OpenSIPS BUT OpenSIPS fails to send ACK to
the Outbound Provider. So Outbound Provider sends 200 OK
again to OpenSIPS and OpenSIPS sends 200 OK to ATA then ATA
acknowledges with ACK back to OpenSIPS BUT OpenSIPS fails to
send back ACK... This dance goes on for 30 secs and until
Outbound Provider drops the call due to no ACK.
On the sngrep it shows that call from ATA to OpenSIPS
"COMPLETED" while OpenSIPS to Outbound Provider "CALL SETUP".
If I comment out topology_hiding("UC"); then everything
works perfectly and sngrep shows only one INVITE dialog from
ATA to OpenSIPS to Outbound Provider except the Outbound
Provider can see everything that is ATA's IP info, etc...
Here is my cfg:
route {
...
if (dp_translate(10 ,$rU ,$rU) ) {
xlog("*** Dial plan translate from source
$avp(src) to $rU ***\n");
$avp(furi) = "sip:xxxxxxx...@gothamcity.com
<mailto:sip%3axxxxxxx...@gothamcity.com>";
uac_replace_from( , "$avp(furi)");
#strip(1);
if (!do_routing(0)) {
send_reply(500,"No PSTN Route found");
exit;
}
# t_on_branch("change_from");
route(relay);
exit;
}
...
}
route[relay] {
# for INVITEs enable some additional helper routes
if (is_method("INVITE")) {
# create_dialog();
topology_hiding("UC");
if(remove_hf("User-Agent")){
xlog("*** 4. User-Agent found and
removed. ***\n");
}
if (isflagset("NAT") &&
has_body("application/sdp")) {
rtpproxy_offer("ro");
}
t_on_branch("per_branch_ops");
t_on_reply("handle_nat");
t_on_failure("missed_call");
}
if (isflagset("NAT")) {
add_rr_param(";nat=yes");
}
if (!t_relay()) {
send_reply(500,"Internal Error");
}
exit;
}
My eyes are sore and my head is spinning... Any help will be
highly appreciated... Thanks!
Cheers,
Nitesh
