<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>
