Dialog module event_route problem - sr-users

12 Aug 2014

Hello;
I am trying to build a prepaid accounting system. I use dialog module's 
start/end event-route. When even_route[dialog:started] triggered, a 
http_query works for the started call. When event_route[dialog:end] triggered , a 
http_query works for call is ended. When http_query works  in 
event_route[dialog:started], i get some CRITICAL ERROR like
'Aug 12 12:16:09   /usr/local/sbin/kamailio[10151]: CRITICAL: dialog 
[dlg_timer.c:205]: update_dlg_timer(): Trying to update a bogus dlg 
tl=0x7f7634d925d8 tl->next=(nil) tl->prev=(nil)'
'Aug 12 12:16:09   /usr/local/sbin/kamailio[10151]: ERROR: dialog 
[dlg_handlers.c:1263]: dlg_onroute(): failed to update dialog lifetime'
Http_query works very well. I can get all call information on Web 
Servers but default_time out or other timeout isn't working.
After i commented out http_query in event_route[dialog:started] , it stopped giving
ERROR but i realized that dialog cannot uptade dialog hash map .I can see all finished
call with "kamctl dialog show". After i closed 
http_query in even_route[dialog:end] , all problems are solved.
I think a problem occured between http_query and dialog event_routes.It 
cannot control dialog lifetime.Any idea about this problem or suggest an alternative way
will be appreciated.My configuration is as follows.
Best Regards
Betül.
