t_relay will create a transaction which will be "alive" in the reply
and failure block.So, effectively, when calling t_relay in the main
route blocks you are handling the message.

2006/8/22, Mark Kent <[EMAIL PROTECTED]>:
As an educational tool, I'm trying to write a pure proxy using
openser. This proxy doesn't have users or domains or gateways,
it just shuffles messages that happen to land on it.
I'm starting with REGISTER where I have simply this:
t_on_reply("10");
t_on_failure("10");
t_relay();
The onreply and onfailure callbacks just log stuff.
The openser cookbook says:
The implicit action after execution of the main route block is to drop
the SIP request. To send a reply or forward the request, explicit
actions must be called inside the route block.
To find what happens in other route blocks (onreply, etc.), I searched
the cookbook for "implicit" and learned:
implicit action for branch_route is to forward the request.
implicit action for onreply_route is to send the reply upstream
according to Via header
And that's all there is. Is there more written somewhere else?
What I noticed is that informational responses (1xx) are not relayed
by openser, but Final (200) or Client Error (401) are relayed.
Is this conclusion correct?
This implicit behaviour seems a little odd to me; I would
think that if I've got a t_on_reply out there then I'm saying
"Hey, I'll handle it" but in fact I cannot handle it (t_relay is
not allowed in an onreply block).
So, I must be missing something in my understanding...
I'ld appreciate it if someone could clarify for me.
Thanks,
-mark
