Hi there,

I have a weird issue with kamailio (latest docker image kamailio-ci:5.5.2-alpine) and http_async_client.

Before posting a lot of logs, let me describe what I want to achieve.

I have a Kamailio and a SIP Phone.

The SIP phone sends a REGISTER to kamailio, then in my routing block, I check if I have an Authorization header.

Since I don't have an Authorization (first message), I use "www_challenge()".

This replies to the SIP phone, and then the SIP phone sends a new REGISTER with the correct Authorization header.

So far so good.

Now, when I get the REGISTER with Authorization header, I want to ask an HTTP endpoint if this user is allowed to connect and check the password using http_async_query().

The problem is that when the transaction resumes, the tmx module is unhappy and throws this error :

30(36) CRITICAL: tmx [t_var.c:546]: pv_get_tm_reply_code(): no picked branch (-1) for a final response in MODE_ONFAILURE

And a 500 error is sent back to the sip phone.

The AUTH_REPLY route is still called and I can use the $http* values.

Do you see something that I am doing wrong or missing in my logic?

Is pausing/resuming to use the async http client is allowed if I'm handling a REGISTER transaction?

Here's a simplified version of my routing block (not far from reality):

##### SNIP 

request_route{

route(AUTH);

route[AUTH]{

    if (is_method("REGISTER"){
        if(no_auth_header){
            www_challenge("$td","1");
            exit;
        }
        else{
            t_newtran();
            http_async_query("http://xxx.xxx.xxx.xxx:9000/auth?foo=bar", "AUTH_REPLY");
        }
    }

}

route[AUTH_REPLY]{

    xlog("L_INFO", "route[HTTP_REPLY]: status $http_rs\n");

}

}

##### END SNIP

Best regards!
