Hi again

I think I have found what goes wrong.
A => B => CFW => C
C has MIN-SE: 900
A is initially sending Sestion-Timer: 600
Without 181 reply:
C replies with 422 Timer too Small Min-SE: 900
This 422 Reply has a ToTag.
A re-initiates the call with a larger session timer, that INVITE has NO
ToTag - new transaction. The Calls succeeds.
Now I repeat the same, but I send a 181 message back to A BEFORE A
receives the 422 from C. That 181 has a ToTag.
Now when A re-initiates the INVITE, it includes the ToTag received in
the 181 and loose_route fails as there is no such transaction.
Is A misbehaving by including a ToTag when it should not? Should the 181
reply not contain a ToTag?
I again tried all variants
* sl_send_reply() generates ToTag
* send_reply() generates ToTag
* t_reply() does not send the reply.
Mit freundlichen Grüssen
