Re: http_async_client

Try this:

    jansson_set("string","from"    , $hdr(From)    , "$var(post)");
     jansson_set("string","to"      , $hdr(To)      , "$var(post)");
     jansson_set("string","call-id" , $ci           , "$var(post)");

$http_req(all) = $null;
$http_req(suspend) = 0
$http_req(method) = "POST";
$http_req(hdr) = "Content-Type: application/json";
$http_req(suspend) = 0;
$http_req(body) = $var(post);

        http_async_query(
            "http://IP:PORT/someurl",  # Endpoint
            "RELAY_API_RESPONSE" # Callback route
        );


Atenciosamente / Kind Regards / Cordialement / Un saludo,
