Looks like http_async_suspend(0); does not work well in v4.4.2.

So my config is ok and I need to add all next logic
with call routing to route[HTTP_REPLY]
,correct ?

Hi,
if you are in a transactional contest (as you are since you are calling
t_newtran()), the script execution is suspended, upon calling
http_async_query and resumed in the callback route passed as parameter.
The instructions after the call to http_async_query are never executed.
If you are not in a transactional contest or you explicitly instruct to not
suspend the transaction ($http(suspend) = 0, http://www.kamailio.org/doc
s/modules/devel/modules/http_async_client.html#idm1053320700) they will
be executed, and the callback route will be run when the http reply comes.
If you want to use http uqeries to retrieve parameters you want to use for
your routing logic, you need to suspend the transaction and resume it in
the callback.
Hope this clarify.
Best regards,
Federico

Hello!
Please help me to understand how http_async_client module behaves. I am
going to use it for call routing according to the http response.
if (is_method("INVITE")) {
t_newtran();
xlog("L_ERR", "ASYNC0-$fU-$rU-$rm---- \n");
http_set_timeout(1000);
http_set_method("POST");
http_append_header("Content-Type: application/json");
http_async_query("http://10.10.10.10:8080/RPC",
"{\"jsonrpc\":
\"2.0\", \"method\": \"ul.lookup\", \"params\":
[\"location\",\"user\"],
\"id\": 1}", "HTTP_REPLY");
xlog("L_ERR", "ASYNC1-$fU-$rU-$rm---- \n");
}
route[HTTP_REPLY] {
xlog("L_ERR", "HTTP_REPLY: ok $http_ok \n");
xlog("L_ERR", "HTTP_REPLY: status $http_rs\n");
xlog("L_ERR", "HTTP_REPLY: body $http_rb\n");
xlog("L_ERR", "HTTP_REPLY: error $http_err)\n");
}
In syslog I see HTTP_REPLY log strings with correct response, but do not
see ASYNC1 string and script execution stops.
What's wrong with this?
