[SR-Users] Transaction good practices with t_relay t_newtran and t_release

[Mickael Marrache]

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.

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.
