Anyway, response routing must always be correct as it is based on Via
headers.
If you want stateful load balancing, you usually hash over a constant
field, e.g. From URI (if you want all messages from a certain user to be
sent to the same Asterisk server) or Call-id (then all messages within a
call will be routed to the same Asterisk)

So I think this is not supposed to work like I want it to. The
dispatcher module is for
stateless processing only, so even though I have RR and TM functions
in my routing script
it does not act properly. I don't think I can use dispatcher for what
I want, which is a
stateful load balancer.
I am looking at 3.0 and carrierroute or lcr module.
Thanks.

You are operating sipp in uac mode - thus it is not capable of receiving
requests.
Maybe Asterisk is send reINVITEs which are not handled correctly by sipp.
set canreinvite=no in sip.conf (Asterisk)

"Discarding message which can't be mapped to a known SIPp call" and
"SIP/2.0 481 Call leg/transaction does not exist"
This happens with kamailio setup stateful or stateless. I'm wondering
if sipp is the problem or just doesn't play well with kamailio?
I've kept the config as simple as possible for testing, it is listed
here http://pastebin.com/BZ8hJvJv
Here is my sipp usage:
sipp -sn uac 10.10.12.53 -i 10.10.14.97 -s 55 -d 7000 -l 10 -r 1
-trace_err
Any insight would be appriciated.
the problem is in your sipp scenario. The uac calls do not map to uas.
kamailio does not reply 481, check the uas scenario, that is the one
that sends back the 481.
Cheers,
Daniel
