[Users] check if transaction exists

[Andreas M.]

Hi Klaus,
you´re right, maybe i described something wrong.

it is ok, when in the first transaction (INVITE-100-180-200) until
code 200, all other invites should be rejected, it is not necessary to 
hold the full state of the call and i know, that ser isn´t doing this.

but, is it possible, until code 200 is sent/received, that all invites 
to this uri are rejected ?

how to identify that there is an transaction ongoing to the called uri ?

regards,
A.Matzel
