Hi,
Thanks for all responses, I think we can do completely without the
t_newtran too now. We got it originally from one of the older CNXCC
routing examples. But it seems we can skip it entirely indeed.
TMX might also be good for us to use earlier transaction detection. I'll
look into that as well.
Cheers,
Dirk

Hello,
there is a rather new lightweight mechanism to detect retransmissions
without creating the transaction before relaying. It is already part of
4.2 and in the default configuration file -- see t_precheck_trans() from
tmx module.
Cheers,
Daniel

Hi,
I think one would like to create transaction ASAP to absorb retransmissions.
In some scenarios, processing a message can take time and retransmissions
are likely to happen, and you don't want the retransmissions to be processed
again (which can lead to errors in some scenarios). t_relay is generally
called at the end for relaying the message.

and t_release
Dirk,
Why do you need to create new transactions yourself with t_newtran()?
Nonexotic applications of Kamailio usually don't require this. A transaction
is automatically created after t_relay() is called, and its lifecycle is
automatically managed - including destruction - based on the replies
received to the transaction-forming request, and based on RFC 3261 rules in
cases of timeouts.
