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 $http* values.It seems that my AUTH_REPLY route is called but considered as a "failure_route"
19(27) exec: *** cfgtrace:dbg_cfg_trace(): failure_route=[AUTH_REPLY] c=[/etc/kamailio/kamailio.cfg] l=665 a=16 n=if
17(23) NOTICE: <script>: [AUTH_REPLY] FAILURE ROUTE
If I remove the http_async_client and try with route(AUTH_REPLY) then it is considered as request_route (but this is not a solution since I need to do this http request)Do you see something that I am doing wrong or missing in my logic?Is pausing/resuming to use the async http client is allowed if I'm handling a REGISTER transaction?Here's a simplified version of my routing block (not far from reality):##### SNIPrequest_route{route(AUTH);route[AUTH]{if (is_method("REGISTER"){
if(no_auth_header){www_challenge("$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");if(t_is_failure_route()) {
xlog("L_NOTICE", "[AUTH_REPLY] FAILURE ROUTE \n\n");
}}}##### END SNIPBest regards!
