Thanks Daniel,
I tried your solution, and it works great!
Not sure it completely fill our needs though, so we'll probably write our
own module (and push it to the community of course :)

Guillaume

Hello,
you may get similar results using t_cancel_callid(():

http://kamailio.org/docs/modules/stable/modules/tmx.html#idm8272
For each call you have to store the call-id, cseq and the target
user somehow (e.g., using htable).
Then, when you have a registration, see if the user has an ongoing
call towards him/her. If yes, cancel that transaction and you end up
in failure route. Based the flags, you can see it was canceled on
purpose and can do another lookup location to get now two branches.
You would need to store the initial caller address before looking up
location, revert to it in failure route before looking up location
again.
The behavior is not exactly the same as you requested, as first
branch is canceled. But given that the branch will be called again
in short time, the user might not notice anything in terms of
ringing interruption.
Alternative is of course writing a function for it, at the end it is
on of the big benefits of open source.
Cheers,
Daniel

Hi,
I would like to do some kind of "late parallel forking" (see the example
below).
Is there a way to do such thing with Kamailio ?
Here is an example:
. A call B
. B device 1 is connected so INVITE is forwarded to it
. B device 2 registers succesfully
. as device 1 as not yet answered and INVITE transaction is not expired, I want
INVITE message
to be forwarded to device 2 (so both are ringing)

Guillaume Bour
