As far as I know, SIPp would not be able to handle Registration,
Subscription and OPTIONS messages in a single scenario unless you can ensure
all of the messages involved come and go with the same Call-ID for each
"session" doing REGISTER/SUBSCRIBE/OPTIONS.
If I had to do it I would write 3 different scenarios and run them
concurrently (start one instance of SIPp for each of them).
To keep registering and subscribing, you just have to use a loop:
<label id="start_of_loop" />
... REGISTER or SUBSCRiBE processing goes here ...
<pause/>
<nop next="start_of_loop" />
Then, if the OPTIONS is sent by Asterisk due to Registration (I don't know,
I never used Asterisk), you must set the IP/Port of a third instance of SIPp
running a UAS scenario and pass this info in the header Contact of REGISTER
(or SUBSCRIBE).
And maybe ims_bench could handle this better (I don't know, I never used
that either)
http://sipp.sourceforge.net/ims_bench/
as it says it improves on SIPp by adding (among other things)
"multi-scenario support".
(Obs: the REGISTER and SUBSCRIBE scenarios, could be merged in a single
one).
