<p>Hello,</p>
<p>the flow chart is this:</p>
<p>-> INVITE (to OpensiSIP)</p>
<p>Relay to Redirect Server</p>
<p>Redirect server reply with a 302 and a contact that OpenSIPs use
to create<br>
</p>
<p>INVITE (OpenSIPs) -> <br>
</p>
<p><- 183 (provider) with Require: 100rel</p>
<p>PRACK (from OpenSIPs)</p>
<p>I don't know how create this PRACK</p>
<p>I have:</p>
<p>modparam("b2b_entities", "passthru_prack", 0)</p>
<p>but this is not enough and I have to use (I think)</p>
<p>b2b_init_request("top hiding");</p>
<p>but this function works only on Request Route and I catch the 302
in the failure route.</p>
<p>Thank you</p>
<p>Regards <br>
</p>

<br>
This is the scenario.<br>
<br>
OpenSIPs receive a INVITE and send it to a server that reply
with a 302 <br>
message (always)<br>
<br>
Then OpenSIPs, in the failure route, take the user part
present in the <br>
302 contact header, change the destination IP and send with
t_relay<br>
<br>
The destination reply with a 183 with Require: 100rel header
so OpenSIPs <br>
have to reply with a PRACK. This is my problem.<br>
<br>
I don't know which is the best way to handle this (the PRACK)<br>
<br>
Thank you<br>
<br>
Regards<br>
