<tt>Hi, Denis!<br>
<br>
Are you modifying the $ru/$rd variables anyhwere in your script
for that ACK? I am seeing the R-URI of the ACK going to
3.3.3.3:5068:<br>
ACK <a class="moz-txt-link-abbreviated" href="mailto:sip:3364021@3.3.3.3:5068">sip:3364021@3.3.3.3:5068</a> SIP/2.0.<br>
However, it should be:<br>
ACK <a class="moz-txt-link-abbreviated" href="mailto:sip:3364021@4.4.4.4:5060">sip:3364021@4.4.4.4:5060</a> SIP/2.0.<br>
<br>
Can you try printing the $ru variable just after the
topology_hiding_match() function?<br>
<br>
Best regards,<br>
</tt>

<title>Opensips 2.2.2 and top hiding</title>
<span style=" font-family:'Times New Roman'; font-size: 12pt;">Hello!<br>
<br>
I try to make top hiding using topology_hiding module.<br>
In attachment you can find a log of unsuccessful call.<br>
<br>
Scheme of the call<br>
<br>
SIP UA (2.2.2.2) -> Opensips with top hiding (1.1.1.1) ->
another Opensis proxy (3.3.3.3) - > PSTN GW (4.4.4.4) ->
PSTN.<br>
<br>
As i understand, the problem is that Opensips proxy cannot send
ACK (on 200 OK) to PSTN GW because RURI and Route header has
similar IP, namely 3.3.3.3.<br>
<br>
I am using "<span style=" font-family:'courier new'; font-size:
9pt;">topology_hiding("C");<span style=" font-family:'Times
New Roman'; font-size: 12pt;">" function for top hiding.<br>
<br>
The call log was gathered from 1.1.1.1<br>
<br>
Thank you for any help.<br>
<br>
P.S. On 1.1.1.1 i also try to make load balancing.<br>
<br>
