<span style=" font-family:'Times New Roman'; font-size: 12pt;">Hello, Razvan!<br>
<br>
I want to make some input point to my SIP network which will make authentication and topology hiding.<br>
Authentication works (i checked it by inserting in client SIP UA wrong password), but b2b doesn`t. <br>
When i try to setting port before b2b_init_request i see in log " ERROR:b2b_logic:create_top_hiding_entities: failed to create new b2b server instance"<br>

<br>
Can you please detail a bit what you are trying to achieve? In the trace attached, all I can see is that OpenSIPS doesn't authenticate the UA - I don't see why it should even try to send the INVITE anywhere.<br>
However, if you are saying that you see both lines in the log, it means at a certain point the INVITE was authenticated and the topo-hiding was engaged. Did you try setting the port before calling b2b_init_request(), in route(1)?<br>

<br>
Opensips 2.2.2.<br>
<br>
I want to make an installation of Opensips which will include auth and top hiding functionality.<br>
<br>
First of all, in the main route, i catch INVITE<br>
"<span style=" font-family:'courier new'; font-size: 9pt;">if (is_method("INVITE") && !has_totag()) {<br>
route(1);<br>
exit;<br>
}<span style=" font-family:'times new roman'; font-size: 12pt;">"<br>
<br>
then, in route [1], i make some auth procedure using "<span style=" font-family:'courier new'; font-size: 9pt;">pv_proxy_authorize<span style=" font-family:'times new roman'; font-size: 12pt;">" and "<span style=" font-family:'courier new'; font-size: 9pt;">proxy_authorize<span style=" font-family:'times new roman'; font-size: 12pt;">" functions<br>
if auth procedure is successful i make <br>
"<span style=" font-family:'courier new'; font-size: 9pt;">xlog("L_INFO", "Route1:$rm was received with auth (IP=$si, IPD=$rd, CALLID=$ci, FROMTAG=$ft, TOTAG=$tt, AUTH=$au) AND B2B prepared");<br>
b2b_init_request("top hiding");<br>
exit;<span style=" font-family:'times new roman'; font-size: 12pt;">"<br>
<br>
In the local route i try to edit port of the destination, using <br>
"<span style=" font-family:'courier new'; font-size: 9pt;">xlog("L_INFO", "Local:$rm was received with auth (IP=$si, IPD=$rd, CALLID=$ci, FROMTAG=$ft, TOTAG=$tt, AUTH=$au)");<br>
rewritehostport("1.1.1.1:5065");<span style=" font-family:'times new roman'; font-size: 12pt;">" <br>
<br>
where 1.1.1.1 - ip address of Opensips.<br>
<br>
In attachment you can see debug of unsuccessful call, where <br>
1.1.1.1 - ip address of Opensips.<br>
2.2.2.2 - caller SIP UA<br>
<br>
I can see in syslog both messages, in local route and in route [1].<br>
<br>
As you can see from the debug Opensips doesn`t try to send INVITE to 1.1.1.1:5065.<br>
<br>
Thank you for any help.<br>
<br>
