Hello,
is any particular reason to do the processing after t_relay() ? You can
do the save before, since it is the same register message.
Also, are you getting this in a testing environment while using tools
like sipp to simulate traffic?
Starting with 3.0, the AVPs (which are associated with the message and
transaction in this case) become available in onreply_route[3] (in 1.x
that was a config option for tm module), so if it is fast reply, it my
happen that the avps are no longer available in the script after t_relay().
As a recommended rule, it is better to avoid using avps after t_relay()
- this function creates the transaction and forwards the message. From
there on, the avps are in the hands of tm module, which moves them to
onreply_route or failure_route, depending on your config file.
Cheers,
Daniel
