Hi Federico,
Hope you are well?
Thanks for the reply, t_newtran()  before http_async_query works perfectly!
Many thanks
Jon

continue

Hi,did you create the transaction before calling http_async_query?If not, the 
function switch to non-transactional context, the script execution is not 
stopped (you should notice it in your logs if the log line after the function 
call is printed) and the callback function creates a fake message to be 
processed in the callback route. 
You should call t_newtran() before calling http_async_query.
Cheers,
Federico

Hi Guys,
I am just testing with jansson and http_async_query.
Essentially I sent an INVITE into kamailio ,it hits CALL_START_REQUEST (see 
below) and the query allows the http site I send to, to provide routing details 
for kamailio.
Logging the $rm that hits CALL_START_ REQUEST, it shows as INVITE, however when 
CALL_START_REQUEST_REPLY is hit, the message type is OPTIONS, is this expected 
behaviour?
Essentially I want it to continue in the script with the same $ci,$rm so I can 
onwards route it for termination, but all I get are options messages being 
sent, any hints please?
As Ideally I want the transaction to continue to a route where I can forward on 
modified request for termination.
Thanks
Jon
