Not sure I got what you mean by "across", English is not my native
language. If you have in mind that A and B are both local subscribers of
CUCM and the call between them has to pass through CUCM, then to do
this, you need much more complex scenarios than the embedded ones. In
particular you need that both register in one thread (a "call" in SIPp
terminology), and then A them initiates a session in another thread,
while B is ready to accept it.
If this is the case: to implement this, you need conditional execution
at UAC side (to take a different branch of the scenario depending on
call number) and an auxiliary timer instance of SIPp at the UAS side, as
the UAS needs to receive an impulse from outside to start a thread. So
while the INVITE-awaiting branch of the scenario is a regular one, the
REGISTER-sending one is triggered by receiving a SIPp inter-instance
command.
I have described this here in deeper detail several times in the past.
Maybe you could start from this message
<https://sourceforge.net/p/sipp/mailman/message/34707334/>.
If it is not the case, e.g. if A or B or both are trunk peers, please
provide a rough flow diagram of what your scenario should look like,
similar to the following one, and indicate which elements should be
replaced by SIPp scenarios and whether they are trunk peers or
registering subscribers. And consider whether we should continue on the
mailing list or whether to move away from there.

Have you ever tried across a Cisco CUCM ?

Yes, provided that you bind each instance to a different port on
the loopback interface (127.0.0.1). This is relevant for UDP, for
TCP the client will choose an ephemeral port for establishing
connection so it won't conflict, but there are other caveats.

Understood.
Is it possible to perform it running uac.xml and uas.xml from
same laptop ?

<mailto:sinde...@ttc.cz>>:
In your scenario, sipp running uas.xml replaces the B
party and sipp running uac.xml replaces the A party.
Depending on which of the parties you want to simulate or
whether you want to simulate both, you need to run one or
two instances of sipp and to choose the uas /uac behaviour
for it/them.
The embedded uac.xml will not send the BYE to an IP
address extracted from any uri received in a response
unless you explicitly tell it to do so and point it to a
particular uri from which it should extract the address.
Similarly, the embedded uas scenario will send the
response to BYE to the same IP from which it has got the
initial INVITE, even if the BYE comes from another one,
unless you explicitly ask it to do do.

Hi
thanks for your feedback.
the purpose is to reproduce a situation where
A calls B
B answer to A without Contact Header and with Record
Route set.
My questions is: would it be enough to use uas.xml
script to reproduce the above or I need to also
trigger a uac.xml too ?

Can you be more specific regarding for which of
the following steps you need assistance?
1) run the sipp binary with a single command line
parameter |-sd uas| , thus asking it to dump the
embedded uas.xml to stdout while redirecting
stdout to file my_uas.xml:
|sipp -sd uas > my_uas.xml|
2) edit |my_uas.xml| the required way (remove
|Contact:..|, add |Record-Route:...|)
3) run sipp with all the command line parameters
you use normally plus |-sf my_uas.xml| , thus
telling it to run your modified UAS scenario
rather than the embedded one
?

Hi
sorry but I'm pretty new with scripting with
this tool.
I would need to reproduce a scenario where
sipp is used to answer a phone call, removing
Contact Header and adding a Record Route field
with option "lr" (loose routing).
A calls B (sipp) . B answers with 180 ringing
without Contact Header and adding Record Route .
I thought to manipulate uas.xml script to
perform that but I don't know how to perform
the action above.
thanks
cheers
