Hi Anton,
if you are looking for dialog- persistent variables, use the dialog
module and the dialog variables:
http://www.opensips.org/html/docs/modules/1.6.x/dialog.html
http://www.opensips.org/html/docs/modules/1.6.x/dialog.html#id295169
Note that you need to create the dialog (at INVITE time) via
"create_dialog()" function before start using the dialog variables.
Regards,
Bogdan

Why BYE isn't a part of the transaction?
From RFC3261:
Specifically, a SIP transaction consists of a single request and any responses
to
that request, which include zero or more provisional responses and
one or more final responses.
But when opensips docs say transaction, it is also implying that you
are using module tm (if you don't use tm functions, then you are doing
stateless processing and no AVP will be saved).
For completeness,
the BYE is part of the dialog established by the INVITE transaction
that ended when "200 OK" was received. But the BYE itself starts
another transaction.
So, the AVPs you set in the processing of the INVITE will be available
(as long as you use module tm) when your process responses for that
INVITE (180, 183, 200 etc), but not when you are handling other
requests in the dialog.

Hello.
During INVITE processing I'm setting up some avp variables.
When I'm
receiving a BYE request all avps are null. Why does this happen?
A part of the script:
if (has_totag())
{
if (loose_route())
{
if (is_method("BYE"))
{
xlog("*** BYE $avp(i:2)");
From the docs
(http://www.opensips.org/Resources/DocsCoreVar#toc2):
"AVPs are part of the transaction context, so they will be visible
everywhere where the transaction is present. "
