<span style=" font-family:'Times New Roman'; font-size: 12pt;">Razvan, i found the problem (there was in reply_route, where i have done fix_nated_contact()). This problem is closed.<br>
But, unfortunately, i still cannot make successful call, and i want to ask you to analyze the new problem it this branch.<br>
<br>
The next problem appears in Opensis proxy (we have the same scheme).<br>
In attachment you can see a call log (trace3) and a log from syslog (trace4). All logs from Opensips proxy (3.3.3.3).<br>
Opensips proxy is the main proxy in my SIP network, while Opensips with tophiding (1.1.1.1) is a new instance.<br>
Opensips proxy serves many calls and i didn`t see such problem before.<br>
<br>
I want to notice you on callid in 183 and 200 code, received from PSTN GW. It is changed by Opensips proxy for unknown reason.<br>
<br>
Thank you for any help.<br>

<br>
Could you also send the logs for INVITE? It seems like the dialog is storing a bogus Contact header.<br>
<br>
PS: please attach the logs on pastebin.com, not directly in the email.<br>

<br>
Load balancing functions can change the R-URI.<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 </span><a style=" font-family:'times new roman'; font-size: 12pt;" href="mailto:sip:3364021@3.3.3.3:5068">sip:3364021@3.3.3.3:5068</a><span style=" font-family:'times new roman'; font-size: 12pt;"> SIP/2.0.<br>
However, it should be:<br>
ACK </span><a style=" font-family:'times new roman'; font-size: 12pt;" href="mailto:sip:3364021@4.4.4.4:5060">sip:3364021@4.4.4.4:5060</a><span style=" font-family:'times new roman'; font-size: 12pt;"> SIP/2.0.<br>
<br>
Can you try printing the $ru variable just after the topology_hiding_match() function?<br>
<br>
Best regards,<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-size: 9pt;">topology_hiding("C");<span style=" 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>
