Hi again, Following up on this and having done some further tests, I was finally able to generate a SIP INVITE request using the following command sequence on the command file.
$uac_req(method)="INVITE";
$uac_req(ruri)=$shv(userAcontact);
$uac_req(turi)="sip:1000@decasa.website";
$uac_req(furi)="sip:1001@decasa.website";
$uac_req(callid)=$var(call_id);
$uac_req(hdrs)="Contact:
<sip:1001@151.236.52.84:5060;transport=udp\r\n";
$uac_req(hdrs)="Allow: SUBSCRIBE, NOTIFY, INVITE, ACK, CANCEL, BYE,
REFER, INFO, MESSAGE\r\n";
$uac_req(hdrs)="Content-Type: application/sdp\r\n";
$uac_req(body)=$var(offer);
uac_req_send();
I've attached the trace collected on the client side. Transaction/dialogue wise
seems to have the correct behavior, however I found two blocking issues which
are causing the SIP INVITE to be rejected with a 400 "bad request" error code.
The first, it seems we cannot send more than one header on the SIP INVITE. That
is I need to add the "Contact", "Allow" and "Content-Type" fields, but only the
last one is inserted, which is the "Content-Type". If I marked it as a comment
(with #), them the "Allow" is included instead.
The second issue is related with the inclusion of SDP offer on the body of the
message. Since this SDP is quite a long one(1266 bytes) it is being truncated.
I'm currently using kamailio 4.3.0.
Thanks,
Joao

Yes, those would be more viable.
