Hello,

If you are already using http_async_reply and therefore processing the request 
stateful, I personally would just stay stateful.
What is your motivation about trying to avoid it?

Cheers,

Henning

Subject: [SR-Users] Performing async_http calls on stateless Loadbalancers

Hi List,

we are running several stateless SIP Loadbalancers using Kamaillio 5.1 and 5.6.
Now we would like to perform an async_http request if an INVITE matches certain 
criteria. The request itself is performed very similar to how it's described 
here [1]
This uses the transaction module in order to assure that the response can be 
mapped to the original request. However, this also means that the processing of 
the entire request becomes stateful which we would like to avoid.

We tried to use t_release() in the callback route (in [1] this route is called 
"RELAY_API_RESPONSE"). However, documentation says that this is only allowed in 
the REQUEST_ROUTE.
Is there an easy way to circumnavigate this issue?

Cheers
