<p>I'm trying using directly opensips-cli via exec module to see

<p>I don't know how use " in the line because Headers and ruri

<font face="monospace">yes, you can use the b2b_logic (together
with b2b_entities) for that, but it may be a too heavy tool
for the purpose. Maybe you can try to generate the PRACK from
OpenSIPS level by using the t_uac_dlg MI function [1] via the
mi_script module [2] - basically to trigger that MI cmd from
the onreply_route, when receiving the 180 reply.<br>

<p>I know the best way is the original caller handle and reply
the 183, but I HAVE to do this at OpenSIPs level.</p>
<p>Can I use B2B_Entities and B2B_logic to do this? Is there a

<font face="monospace">I agree here, the 183 must be relayed
back to the original caller (which generate the received
INVITE) and let it do the PRACK - this confirmation must
be end-2-end in the dialog.<br>

<div>You should relay 183 to original source (ione that

<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>
