Hi Andreas,

You don;t have to change anything in the opensips script (for adding the pre-call media server), but only in the XML scenario.

Take a look at the marketing scenario (in the B2B tutorial), where after a caller is connected to an announcement, upon announcement termination, the call is sent to callee side.

Could you post your XML scenario ?

Best regards,

Hello

I wanted to test the B2B script-scenario prepaid from the B2BUA tutorials.
The only change I wanted was to only invoke a MediaServer before connecting the call to B-party.

Note my OpenSIPS is running regular proxy/registrar functions besides B2B.

The B2B is able to setup the call towards MediaServer and trigger on receiving BYE.

The next leg towards the actual B-party is not setup as OpenSIPS doesn't see this as B2B? but does authorization for that INVITE request, which fails.

I believe it's due to the B2B doing somethingsomething to my URIs and/or CSEQs.

My issue seems very much like something I found in a previous post (https://opensips.org/pipermail/users/2010-February/010931.html) but there was no final solution.

I trigger this for the initial INVITE as such:

    if ($rU =~ "^\+1234567890.*") {

# t_newtran is necessary because b2b should not handle retransmissions.
        if (!t_newtran()) {
           sl_reply_error();
           exit;
        }

xlog("L_WARN","B2BUA cid=$ci, Call from $fU to $rU initialized as B2B\n"); b2b_init_request("freecall", "sip:+9999@1.2.3.4:5080 <http://sip:+9999@1.2.3.4:5080>");
        exit;
    }

My B2B scenario file: https://pastebin.com/KwpgJziL

Any clues to what the solution from Anca was in the original post referenced above or any other ideas as to what I am doing wrong here?
