Hello, you can send arbitrary status codes back in the http reply, I think. Just get the SIP status code and use it. There are async client http modules that offers resume functionality for the client side.

Is it possible to send the SIP status code back in the HTTP reply? Is it possible to suspend an xhttp request while some other stuff happens and then send the reply later? The relevant bit of the config currently looks like event_route[xhttp:request]{ if($hu == "/sms"){ $uac_req(method)="MESSAGE"; $uac_req(ruri)="sip:1234@example.com"<sip:1234@example.com>; $uac_req(furi)="sip:4567@example.com"<sip:4567@example.com>; $uac_req(turi)="sip:1234@example.com"<sip:1234@example.com>; $uac_req(body)=$rb; uac_req_send(); xhttp_reply("200", "OK", "text/plain", "Sent") } } Regards, Tim
