[OpenSIPS-Users] loose_route with opensips 3.2 B2B module

[xaled at web.de]

Hi,

would it be possible to respect loose routing on the caller side of B2B module and set route header on the callee side accordingly 

Something like this:

Incoming INVITE:

INVITE sip:+12345678 at 1.2.3.4;user=phone SIP/2.0
Via: SIP/2.0/TCP 4.3.2.1:5060;branch=z9hG4bK40365b83fb9732a054d124bb46252151.7242beeb
Route: <sip:orig-test at test.com:5060;transport=tcp;lr>, <sip:605e7788/5.1.0.17 at 4.3.2.1:5060;transport=tcp;lr>

Wanted outgoing INVITE:

INVITE sip:+87654321 at 1.1.1.1;user=phone SIP/2.0
Via: SIP/2.0/TCP test.com;branch=z9hG4bK40365b83fb9732a054d124bb46252151.7242beeb
Route: <sip:605e7788/5.1.0.17 at 4.3.2.1:5060;transport=tcp;lr>

I tried setting loose_route in both the original route and in the resulting b2b route but without success.

route[b2b_test_logic] {

<------>loose_route();

    if ($rm != "BYE") {
        # for requests other than BYE, no special actions needs to be done,
        # just pass the request to the peer
        b2b_pass_request();
        exit;
    }
...

Thanks,
Xaled
