Hi,<br>
<br>
All sequential requests of the b2b dialogs will not be visible in
the script. The fact that you get the ACK in the script means
opensips b2b failed to match the ACK with any of the b2b dialogs.<br>
And looking at the trace, this happens because of the bogus TO tag
in the ACK request ; the bogus tag param is a result of the double
TO hdr in the 200 OK from b2b to carrier :<div class="im"><br>

Once in short format "t", once in long forma "To" - this seems to be
an issue in the b2b.<br>
<br>
First of all be sure you are using the latest 1.8 sources from SVN
(or use the SVN daily generated tarball) - I want to be sure you
have all the fixes in your sources.<br>
<br>
I tried to reproduce this scenario (pushing your INVITE into a b2b),
but I failed to get the 2 "to" hdrs....<br>
<br>
So: (1) update, (2) see if problem still there, (3) update me
please.<br>
<br>

<br>
<br>
I am using Opensips 1.8.2 tls, with B2B UserAgent, running the
default scenario "top riding". <br>
The idea of this implementation is just to pass the packages
between the carrier and the PBX, hiding the topology.<br>
I'm facing a problem to process the ACK requests after 200 OK
(answer), and I guess that all the in-dialog requests after
first INVITE. The ACK requests are beeing forwarded<br>
by t_relay() method, but that is not keeping the previous
dialog, nether hiding the topology.<br>
Should I execute b2b_init_request("top hiding") to ACK requests
as I do to INVITE, or the top hiding scenario was supposed to
generate the ACK automaticaly to 200 OK reply, as is described
in the <a href="http://www.opensips.org/Resources/B2buaTutorial#toc11" target="_blank">tutorial</a>:
"Once you ask b2b to handle a call, you <b>won't see the future
in-dialog request in the normal route</b>."?<br>
<br>
Do someone has an example about how it is supposed to be the
processing of the in-dialog requests with b2b top hiding? Am I
doing something wrong in the script that follows?<br>
<br>
Thanks in advance!<br>
<br>
Here follows the opensips.cfg:<br>
