Hi,
Question: Is there a way to forward a reply from the reply route and do other stuff afterward? We are currently doing operations on a 183 reply and it would be useful if we could forward the reply before continuing to process other stuff.
High-Level example:
*route { t_on_reply("REPLY"); t_relay();}onreply_route[REPLY] { // Forward the reply to the Caller t_relay(); // Does not work, as t_relay is only allowed in request and failure-routes // Do other fancy stuff, e.g. a DB Update or anything else}*
Any ideas?
Thanks, Carsten

I don’t know how to do it that way, but I would add stuff to mqueue and process it asynchronously in the background.

I think that what Olle suggested is a good solution.
Otherwise, for tm onreply_route, using t_reply() can make tm generate its own reply and you can use it to overwrite the incoming reply, but I am not sure it works for 200ok -- for 300 or greater should be ok-ish all the time, unless you want to propagate all headers coming in the received reply.
For core (stateless processing) reply_route, there is:
- https://www.kamailio.org/docs/modules/stable/modules/sl.html#sl.f.sl_forward...
But then be sure you also use drop not to send the incoming reply as well.
Maybe for tm onreply_route, a variant of t_reply() without parameters can be added, and in such case the incoming reply is forward without any change in code and reason text. But could be a little bit tricky/risky, because the state of transaction is updated when the reply is sent out, setting it in terminated state, and the timer ticks till it is going to be destroyed in about 5 secs (with default params).
Cheers, Daniel

+1 — I think this is the way to go. Just push the workload off to some other async routine.
Since 5.6.0 there is forward_reply() in corex module https://kamailio.org/docs/modules/5.6.x/modules/corex.html#corex.f.forward_r... it doesn't have enough description but looking at the source it calls core->do_forward_reply function which ( at least as I see ) doesn't block the execution of the further script commands.

I would use *http_async_query()* in the onreply route, delegate some of the DB update an other stuff to an HTTP server. And if there is a need to further interact with K, there is a way to specify an HTTP reply route that will be called asynchronously.
See : HTTP_ASYNC_CLIENT Module (kamailio.org) https://www.kamailio.org/docs/modules/stable/modules/http_async_client.html
