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 ?

<sinde...@ttc.cz<mailto:sinde...@ttc.cz>>:

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
Marco
